Researches On Around-Rock Control Techniques Of The Fully-Mechanized Faces And Roadways Under Large Mining Height

Through systemically testing and academically analyzing the mining pressure data of mine Kangjiatan of Shendong Coal Co. and mine shaqu of Huajin Coal Co.,the law of mine pressure in thick coal mining working face and adjustability of Mobile Roof Support for thick coal mining working face roof and supporting methods of laneway surrounding rocks. Particularity of roof management in thick coal mining working face and laneway surrounding rocks deformation were analysed in theory .The law of laneway surrounding rocks deformation in thick coal mining working face was mastered.Laneway in goaf for venting gas was imitated by the large general programme of ANSYS 8.0 in the paper . Through the practical engineering circumoustance the paper anlyse the pressure and deformation of surrounding rocks in laneway reserved for venting gas after mining.The stability of the laneway reserved for venting gas is demonstrated in theory.The research about roof management in working face and control techniques of surrounding rocks of laneway will intruct to solve the problems happened during mining...
