Relocating Matla Mine 1

Following 42 years of operating at Matla Mine, Exxaro Resources’ executive decided to relocate the Mine 1 operation, which has been on care and maintenance since 2016, due to safety concerns. By Dineo Phoshoko

The Matla Mine 1 relocation project is a capital project of Eskom at Exxaro’s Matla Mine, which involves the construction of a new decline shaft to gain access to the remaining economical two-seam coal reserves. The relocation project also includes plans to supply Mine 1 with five complete suites of underground continuous mining equipment and equipment used to construct supporting infrastructure, interseams between Mine 2 and Mine 3, and a ventilation shaft to supply fresh air to Mine 3’s future production areas. The project commenced in August 2020 and is expected to be completed during the second half of 2023.

Resources and reserves

Speaking to Inside Mining magazine, Johan Meyer, executive head: Projects and Technology, Exxaro, explains that below the Matla Power Station lies a lot of coal that is accessed by three main shafts. From these shafts, Matla Mine is able to produce 10 million tonnes at a consistent quality of 19.5 CV (calorific value), which is required to feed the power station in order for it to produce the required energy output.

Due to the history of the mine, it has become far to travel to the mining front. “The mining front at that point in time was around 25 km from the entrance of the current Mine 1. So, it’s best to move the shaft closer in proximity owing to this distance and obviously from a safety point of view,” Meyer says. In addition to addressing health and safety concerns, the relocation project will bring the shaft closer to mining activities, which is more efficient than travelling 25 km underground before arriving at the coal face. Meyer adds that the move of Mine 1 is closer to where the coal is, but still within the vicinity of the Matla Power Station. As such, the mine can continue to feed the power station from the conveyor systems below the ground.

Impact of relocation on employees In terms of Covid-19, Meyer mentions that nobody There are approximately 2 000 permanent employees anticipated that contractors would be required to working for Matla, as well as 2 500 contractors. “Without wear masks, have PPE and socially distance when Mine 1 being established, it would have been difficult Exxaro initially tendered for the project. He adds that to keep the resources with only two shafts running,” Exxaro employees were among the essential services says Meyer. The Mine 1 relocation project means that workers throughout the various lockdown levels, as approximately 4 500 employees and contractors will the company supplies coal to Eskom. It was during continue to have jobs for an extended period – until this time that everybody familiarised themselves 2040, when the resources become depleted. with Covid-19 regulations. Meyer also notes the project will create employment “We are working with the Minerals Council South for an additional 1 200 contractors required to work Africa and Exxaro Projects, as well as the mine, to on it during its duration. This will further have a implement all the regulations of social distancing positive impact on the local Kriel and PPE. We have compliance officers to make sure We have an exciting economy. Meyer highlights that that we wear masks, etc.” Undoubtedly, Covid-19 story of growth and the project will also create hope in tough circumstances, especially has had a significant impact on the project and has created additional costs. While the impact is sustainability for the with the Covid-19 pandemic that being carefully managed, Meyer maintains that the Kriel community.” has impacted many people. “We pandemic will not affect the implementation of have an exciting story of growth the project. “With this pandemic, we have to move and sustainability for the Kriel forward as an economy and [together] as a nation. community. I’m very excited about this project, not only We will implement projects and continue mining as for Exxaro and Eskom, but also for the country.” best we can to support Eskom to keep the lights on in South Africa,” he says. Financing and Covid-19 “There are a lot of stakeholders working together As a joint capital project between Eskom and Exxaro’s to make this a success.” They include the unions, Matla Mine, the supply agreement sees Eskom Kriel community, Department of Mineral Resources providing the capital that has already been released to and Energy, the construction industry and internal build the mine. The collective move for the mine, box Exxaro stakeholders. Meyer concludes that this cut, surface infrastructure, conveyors, ventilation shaft project is a success story about building hope – and additional five sections of mining equipment for especially during the Covid-19 pandemic and amid Mine 1 will cost around R3.5 billion. many economic challenges.
