Předkládaná odborná studie analyzuje současné a potencionální zdroje karbonského plynu v české části hornoslezské pánve, především však v oblasti, kde již těžba plynu probíhá. Jedná se o těžbu plynu z již uzavřených dolů v ostravské, petřvaldsk a také karvinské dílčí pávni a také o těžbu plynu pocházející z oblasti činných černouhelných dolů v karvinské dílčí pánvi (Doly Darkov, ČSM a Karviná) a v příborské oblasti (Důl Paskov).

Project monitoring the stress-strain state of the rock mass during extraction of coal seam 30 (634) within the test run mining methods corridor - a pillar in the OPJ Mine CSM - Sever. Proposal verify the possibility to use anti-shake prognosis and prevention using mining methods corridor - pillar within pilot operation in seam 30 (634) in OPJ Mine CSM - Sever

On the basis of a contract for No. 850/33/10 and Appendix 1 of this contract , between OKD , as, ČSM and the Institute of Geonics AS CR, v.v.i. we present the following project monitoring stress tension-deformation condition of the rock mass during extraction of coal seam No.30 (634 ) within the test run mining methods corridor - pillar in a protective pillars jam CSM Mine, north location. Monitoring of the stress tension-deformation state of rock mass is a prerequisite for successful verification of a new mining method unapproved hall - pillar and its further use in the Czech part of the Upper Silesian Coal Basin. This mining method is designed on the basis of experiences and practices, which are verified in different natural conditions and depths, and therefore it is necessary for the verification of the conditions of the Czech part of the Upper Silesian Basin on the basis of the proposed geotechnical monitoring. Test operation of the new hall - pillar method will be implemented in the seam No.30 (634 ) in the rock mass included in the category without the risk of shocks.
