PLAVECKÁ ABYSS PP-2 Jaroslav Butaš In 1996 members of Plavecké Podhradie speleological group and Speleo Bratislava realized new examination of Plavecká abyss PP-2 (before called as a Cable cave, Malé Karpaty Mts.). The result of this examination was a suggestion for new exploratory works. Spade-works on introductory parts of Plavecká abyss took whole following year. During this year we prepared a cableway for exploratory works and we also eliminated dangerous hanging rock-blocks. The exploratory probe has been situated in the south part of an abyss. The material from an upper part of our probe formed a mixture of rock-blocks with sinter crusts and the soil. The thickness of sinter crusts was from 50 to 70 cm. The work in following buried parts of a probe was very complicated, because free rock-blocks were unstable. For any advancement has been necessary to construct reinforcement. Steel pipes with Ø 60 mm

have been used as a reinforcing material. The reinforcing cage has a square shape with proportions 1 × 1 m and it has been gradually constructed from up to down parts. The material from the probe has been mined out to top parts and our advancement was cca 1 m for one exploratory action. The free space has been found in a depth of 5 m and our observations confirmed a potential for further 30 m of a free space. For new advancement has been necessary to enlarge a bottom part of the exploratory probe. The enlargement of the bottom part took two exploratory actions and then we are able to descend on the bottom of new parts. The D-day happens 13.7.2002 and the pri vilege of the first descend was attributed to Tomáš Ďurka from Speleo Bratislava. Plavecká abyss PP-2 is situated on the western side of the castle hill near to Plavecké Podhradie village. Surrounding rocks according to geological
