Abstract

This design research studies an abandoned coal mining site located in the Hunter Valley, a famous coal production area in New South Wales, Australia, where is now requiring restoration. It aims to revitalise the post-mining landscapes, reconstruct the biological balance, explore the ecological restoration of coal wasteland, and improve local economy. The research investigated the history, spatial characteristics, physical conditions of Liddle mine. Drawing on related precedents and existing design techniques, the iterative design solutions experiment with restoring the ecological system and creating new ones, preserving and promoting industrial heritage, and revitalising local economy. The final design reveals the feasibility of revitalising coal mining site, the combination of natural and coal industry landscape. A multifunctional landscape is introduced. A ‘black gold square’ and a ‘coal museum’ preserve the mining heritage, reflect the history and contribution of the mining industry as well as explain its impacts. A new natural landscape is introduced, including the forests, indoor garden, green buffers, wetlands, and a creek. The proposal seeks to reduce impacts of pollutions on surrounding communities whilst generate new economic opportunities by promoting tourism, entertainment and education linking to Australian mining legacies.

1.2 The current status of global coal resources The development of the global urban industry has put tremendous pressure on the environment. Human production and life have led to global warming, especially the use of fossil fuels in power generation. It not only destroys the atmosphere during use but also destroys the original ecosystem. Coal is the second-largest energy source supporting human activities.

1.3 The current status of Australia coal resources and power stations Coal is distributed in all states in Australia, but more than 95% of coal is concentrated in New South Wales and Queensland. 70% of Australia’s coal production is used for exports (Energy Information Administration 2011). Coal exports are Australia's secondlargest source of export income, exported to countries including Japan, South Korea, China, Thailand, India and other countries (Cunningham, Uffelen & Chambers 2019). The remaining 30% is used for power generation. Coal accounts for 80% of Australia’s total power generation. This electricity is used for people's production and life.

1.4 The current status of NewSouthWales coal resources Coal production in New South Wales accounts for 23% of Australia's coal production (Geoscience Australia 2013). The surrounding coal mines are transported to the power station for power generation. At the same time, the Liddle power station provides electricity for the production and living of residents in the Sydney basin, including Sydney and Newcastle. The Liddle power station and Liddle coal mine in the core area will be abandoned in 2022 (Cockburn 2017).

1.5 The current status of Hunter Valley coal resources

Hunter Valley is the largest coal producer in New South Wales. Newcastle is located in the Hunter coal mine in the Sydney basin and is the world's largest coal export port (The New South Wales Government n.d.). Coal mines play an important role in the economy.

ps National Park

Ocean Hunter Valley is a famous coal production area in New South Wales, Australia, about 15Km of Muswellbrook, 170 km north of Sydney and 90 km northwest of Newcastle. Geologically, Hunter Valley is situated in the northern parts of the Sydney basin, bordering the New England region. There are rich resources, including coal mines, wine production, horse feeding, agriculture.

1.7 Research Question Research question How landscape design solves issues left by the coal mining industry in the post-industrial era? How to use ecological restoration methods to solve the pollution problem of coal mines? 3.How landscape improve and create new oppotunity to coal mine and local communities , including Muswellbrook, Singleton and Sydney Basin residents?

The theme of this project explores the ecological restoration of coal wasteland, landscape reconstruction and economic revitalization. How landscape design solves issues left by the coal mining industry in the post-industrial era? The landscape design research with the theme of coal mine revitalization is shown in the following research phases. This research starts with the establishment of the project presents the content of the project. The process also includes explores the history of the site and the analysis of surrounding community resources, explores the theories of related scholars, studies cases related to coal restoration, and defines project the research position and appreciation. The design process of this project uses landscape iteration and cartography research methods. First, the design study investigated the current location and operating conditions of the Liddle mine to test the practicality of the design. Secondly, conduct research on related precedents and explore solutions to related topics. It is concluded that the design strategy and design technology are divided into four parts: ecological restoration, establishing ecosystem, industrial cultural heritage and economic revitalization. Solve the research problems and feasibility of the design through the test design of the site. Further, strengthen and supplement the design strategy. Finally, a design plan was produced to explore the feasibility of revitalizing coal mining areas.

1.8 Addressed UN Sustainable Goals Landscape design research recognizes the importance of the United Nations Sustainable Development Goals and incorporates SDG6, SDG7, and SDG15 into its research fields, including clean water and sanitation, Ensure access to affordable, reliable, sustainable and modern energy for all, Life on land. These inclusions are very specific to form the research focus, and specifically connect people's lives.

6.3 By 2030, improve water quality by reducing pollution, eliminating dumping and minimizing release of hazardous chemicals and materials, halving the proportion of untreated wastewater and substantially increasing recycling and safe reuse globally

7.A By 2030, enhance international cooperation to facilitate access to clean energy research and technology, including renewable energy, energy efficiency and advanced and cleaner fossil-fuel technology, and promote investment in energy infrastructure and clean energy technology

15.3 By 2030, combat desertification, restore degraded land and soil, including land affected by desertification, drought and floods, and strive to achieve a land degradation-neutral world

The Sydney Basin includes residents of Hunter Valley, Muswellbrook, and Singleton, and workers engaged in coal work. The coal company is the target customer of the design project. I represent them as landscape architecture activists to formulate landscape design plans to reduce the impact of coal mining and coal abandonment. The coal restoration plan will be the legal basis for design and research, and coal companies are obliged to formulate a restoration plan after coal mining. It is expected that government and non-government offices will participate in different sectors of the development plan. This Design Research Compendium (DRC) is for the above-mentioned stakeholders to use appropriate landscape architecture strategic master plans to meet their needs.

Coal Mines

2.2 Terrain Analysis in Hunter Valley Terrain Analysis: The overall terrain of Hunter Valley is relatively flat. The southwest and northeast directions are higher and are forest parks. The northwest and southeast directions are plains, especially the southeast direction is the Sydney Basin, which is a place for human activities and habitation. This terrain causes Hunter Valley winds to be mostly northwest and southeast winds.

2.3 Agriculture In Hunter Valley

Hunter Valley's existing agriculture is mostly located on both sides of the Hunter River. Mainly for planting and animal husbandry. Muswellbrook was originally an agricultural center. However, due to the development of coal, the agricultural planting area in Hunter valley has decreased.

2.4 Coal Mines In Hunter Valley

The coal in Hunter Valley is mainly open-pit mining. The black areas are the main coal mining areas, including abandoned mining areas. The shaded areas are coal storage areas. Over time, these areas will gradually become open-pit coal mines. In the next 50 years, coal mining areas in these areas will be abandoned due to the exhaustion of coal resources and the application of new energy. Here, Yuyao has a guiding policy to restore coal mining areas and help local economic transformation.

2.5 Water Resources In Hunter Valley The coal in Hunter Valley is mainly open-pit mining. The existing water resources are mostly distributed around the mining area every day. Coal mining destroys the surface and groundwater while leaving a large amount of coal gangue. Water resources in coal mining areas are seriously polluted. And these polluted water will affect the entire Sydney Basin. Primitive rivers and creeks in the central area of coal are cut off, groundwater circulation is destroyed, and lakes disappear.

2.6 National Park In Hunter Valley The coal in Hunter Valley is mainly open-pit mining. Coal mining cuts down a large amount of vegetation, which has severely damaged the local ecological system. Existing vegetation is mostly distributed in national forest parks, and the vegetation in coal mining areas is mostly destroyed.

Chapter 3. Legacy Issues of the Post-coal Industry in Hunter Valley, NSW, Australia

The first coal mining began in Muswellbrook in the 1890s. Muswellbrook began to transform from an agricultural center to a coal industry. Sourse: Numerous abandoned mines are to be seen in the Newcastle coal field. In some instances small amounts of pillar coal are produced for years following the cessation of major perations. Bordering lands are devoted to permanent pasture by Clifford, 1941.

The Hunter Valley open pit coal was mined in 1944. It began to become a major coal mining area and coal producing area in New South Wales. Sourse: An open-cut coalmine in the Hunter Valley. The NSW Minerals Council says 21 as-yet-unapproved projects would boost the economy by Alamy, 2020.

Open-pit coal mining in the Hunter Valley has led to increased water pollution in the Sydney Basin, increased chemical content of surface water, and reduced water quality. Sourse: A Lake Macquarie community group has slammed a recommendation to approve the expansion of Eraring Power Station's 35 million tonne coal-ash dam by 5 Million cubic metres by Kelly, 2019.

The special terrain of the Hunter Valley causes the wind direction to be mostly northwest and southeast. The coal gangue left over from coal mining and the abandonment of power stations have severely affected the Sydney Basin, resulting in a continuous decline in air quality. Sourse: Air quality in the Upper Hunter has breached national standards more than 700 times by Bernasconi, 2019.

3.1 Soil Changed and Coal Gangue The coal in Hunter Valley is mainly open pit mining. The mining of coal destroys the original flat terrain. The process of coal mining is to remove the topsoil to the surrounding area and then mine the coal. As time goes by, the depth of the mining area increases, usually reaching a depth of 200 meters. After mining, in order to save costs, most mining sites leave coal gangue.

3.2 Water Pollution Problems

Coal mining destroys the surface and groundwater while leaving a large amount of coal gangue. Water resources in coal mining areas have been seriously polluted, including chemical substances PH, TED, TSS and EC that have exceeded the standards. And these polluted water will affect the entire Sydney Basin, and the decline in water quality will affect people's production and life. The original rivers and creeks in the coal center area were cut off, the groundwater cycle was destroyed, and the lake disappeared. These surface waters also affect agricultural production and life.

3.4 The destruction of biodiversity - Disappeared Vegetation

Coal mining has led to the disappearance of the original vegetation on the site, such as Central hunter box ironbark woodlands, Aquatic or riparipn vegetation, Central hunter swamp oak forest, Derived grassland and Central hunter bulloalk forest. The disappearance of these vegetations also destroys the local animal habitat and reduces the local biodiversity.

Th e S y d n ey B a s i n Re s e d e n t s H e a l t h Problem

In 2012-13, the National Pollutant Inventory reported that coal sources in the Singleton area produced 1,300 tonnes of PM2.5 (from 11 coal mines) and 5 tonnes of PM2.5 from the Redbank Power Station. In the Muswellbrook area in 2012-13, 730 tonnes of PM2.5 was produced from six coal mines and 680 tonnes of PM2.5 from two coal-fired power stations (Bayswater and Liddell).This indicates the health costs associated with PM2.5 emissions in the Singleton and Muswellbrook areas in 2012-13 amounted to $47 million and $18.3 million respectively - a total cost of $65.3 million.

6.1.1 Outdoor Open Forest Park

The outdoor forest park has introduced six main types of forests. Introduce Pioneer phytoremediation sites for soil pollution and improve soil quality. At the same time, some pioneer vegetation will be retained after 50 years, new plants will be introduced, and the ecosystem of coal mining areas will be restored. The introduction of new economic plants and native plants can quickly establish a new forest system. The introduction of native plant eucalyptus can provide habitat for local animals and increase biodiversity. Economic plants such as apple trees and grape vines can bring new opportunities to the site. People can learn the history of coal mining and geological education at the nodes, and they can pick apple and grape groves at the same time. People can walk through the forest through the air corridor, or enter the open forest at close range to experience cycling. Different watching towers have different heights, giving people different visual experiences. Visitors can overlook the entire coal mine park, feel the forest at their feet, or walk through the forest and walk in the forest.

6.1.1 Outdoor Open Forest Park

The design reveals the feasibility of revitalising the coal mining site, the combination of natural and coal industry landscape. Watching tower as a node is also a "coal museum", which preserves the mining heritage and reflects the history and contribution of the mining industry. The newly introduced forest has repaired the problems left over from coal mining, restored the ecosystem and created a new ecosystem, and also brought more activities and experiences to tourists.

6.3.1 Open Forest Experience

This part shows the Watching tower as a mixed and crossed area of the forest. People can experience two different forests, eucalyptus forest and narrow leaved ironbark bullark, and they can also learn the history of the coal industry and industrial sculptures. Visitors can see the soil remediation device, calling on people to establish a balance between the environment and the economy. The unique industrial landscape and natural landscape can provide photography enthusiasts with a lot of materials. The surrounding residents can go for a run and bike ride in the forest, or take a picnic with their children to experience family time. On the other hand, the establishment of forest systems brings opportunities to the ecological environment. Native plants provide habitats for local birds and animals, creating a new ecosystem.

6.2.2 Wetland - Black Gold Square

The Black Gold Plaza showcased the restoration of the coal industry ruins and the water system and the establishment of a new system. The Heijin Square is located at the bottom of the coal mining area, and the pollution is the most serious. Groundwater and surface water destroyed during coal mining gather in this place, causing excessive chemical composition and serious pollution. The coal site in Heijin Plaza includes ecological elements that have been affected by coal mining, including soil, water, vegetation and animals. Heijin Plaza showcased the restoration process of the site ecology, created a new ecological system, established a link between economy and environment, and called on people to pay attention to environmental protection while developing the economy. As an industrial site, Heijin Square uses sculptures to show the history of local coal development and the production and life of coal workers.

50 year

The first solution to the Black Gold Plaza section is the pollution problem. Use ecological methods to repair water pollution and soil pollution. Use pioneer vegetation to remediate soil and reduce industrial wastewater within 20 years. Complete soil remediation within 30 years, re-introduce river water, and promote the establishment of groundwater circulation. Within 50 years, connect the introduced river water with the groundwater in the site to form a wetland and create a new water system. 20 year

6.4 Design Research Outcome

The expected result of the landscape design plan provides an appropriate physical environment for everyone and can also create new employment opportunities for residents. The development of new energy, the exhaustion of coal resources and other factors have led to the closure of coal mining in the Hunter Valley within 50 years. 30% of residents are engaged in coal-related jobs, and they will also face the problem of unemployment. Therefore, the landscape project researched and tested the economic transformation of coal mining areas and brought new opportunities to residents. The program has the potential to enhance the local people's economy by using characteristic landscape terrain, industrial culture and natural environment. In the process, the plan has achieved the sustainable goals of the United Nations and met local laws and policies, which will help companies start the project with the help of the government and the international community. In coal mining, the government requires companies to retain topsoil. In the process of landscape restoration, the landscape research project can backfill the soil rich in plant seeds and potential, which will greatly reduce costs and quickly restore the local ecology. This backfilling work and land restoration process can provide employment opportunities for laid-off workers. At the same time, after the establishment of tourism projects, the arrival of tourists can stimulate the original local economy, such as red wine, wine cultivation, animal husbandry, horse breeding and service industries. Similarly, the restoration of the ecological environment can reduce the health risks of surrounding people and reduce the risk of lung disease and cancer.

Chapter 7. Conclusion

7.1 Conclusion

The revised landscape design study “aims to study appropriate landscape methods that solve the adverse effects of the ecological problems left by the coal industry, such as land destruction, soil infertility and chemical pollution, coal gangue pollution, excessive chemical substances in the water, and the disappearance of vegetation. Other landscape events have restored local biodiversity and ecosystems, and ultimately helped the local coal industry complete the economic transition from industry to tourism”.The design provides three different scale strategic master plans, large (coal mine), medium (Indoor greenhouse garden, outdoor forest park and wetland) and small (the layered forest, watching tower and black gold square). In the small-scale design for the restoration of plants-different forest forms, soil restoration and geological education-watching tower and water pollution control-black gold square, the specific application of three different restoration methods form different characteristic landscape projects, combining natural landscapes and humanities the landscape is combined. The landscape design research process combines the research strategies and sites learned in theoretical research and case studies to formulate an overall strategic plan suitable for coal restoration. These strategies guided the site planning, formed a characteristic coal landscape project, and completed the themes of ecological restoration, landscape reshaping and economic revitalization.

The design research includes the restoration of site plants, water pollution restoration, soil restoration at different stages and landscape forms, the establishment of wetlands, outdoor forest park, indoor greenhouse garden, geological education museum and barrier zone and other characteristic landscapes. Human activities include different angles and different visual experience of stages and different times. These details prove the effectiveness of the generated landscape design plan, which can meet all industrial landscape events and has strong adaptability, thereby guiding the restoration and economic transformation of the mineral industry, strengthening the connection with the surrounding communities, and calling on people to establish the sustainable economic system.

7.1 Conclusion - workflow

In the first stage, people are not allowed to enter the venue for activities. In the coal restoration stage, it can provide land-off workers and residents with new opportunities, including site construction, coal gangue installation and soil transportation. Through the enrichment and improvement of pollutants and physical effects of pioneer vegetation such as Setaria, shepherd's purse, kangaroo grass etc. Reclamation of the soil, along with the continuous improvement of soil quality. In the second stage, people can enter the venue for activities, but only for voluntary activities. During this period, after the restoration of pioneer plants, the soil of the site can satisfy the growth of trees to a certain extent. Select pioneer trees for further soil restoration and improve soil quality. At the same time, during this period, the waste water area was reduced and the quality improved. The water in Liddle lake has undergone ecological restoration to a level that can be visited up close. But people are not allowed to participate in water sports. In the third stage, people can enter the venue for activities and experience the forest and wetland up close. During this period, through early ecological restoration, the quality of soil and water improved, and an ecosystem was initially formed. In terms of plants, economic plants can be introduced to provide visitors with different feelings and experiences. At the same time, after restoration, water can be introduced into the northern wetlands for further purification and upgrade the water system of coal mining areas. The fourth stage is economic revitalization. The ecological system of coal mining area is completely restored. Tourists can participate in various activities. Feel the experience of forests and wetlands. The completely purified river water is introduced into the wetland. Groundwater and surface water meet drinking standards, and wetlands, rivers and lakes complete the water system. This strategy has been tested to be feasible. Hunter Valley also has a large amount of coal mining land. This strategy can be applied to every coal mining wasteland. Eventually, ecological restoration of coal mining areas, landscape reshaping and economic revitalization will be realized.
