东保卫煤矿大倾角煤层回采巷道围岩控制技术研究

Steep Rock Control Technology in East Defense Coal Mine

根据东保卫煤矿41层-280m综采工作面煤岩赋存条件和开采技术条件,通过对大倾角煤层回采巷道围岩的变形规律和矿压显现规律研究,进而为回采巷道围岩控制提供理论依据,并对回采巷道锚杆支护关键技术进行分析,保证了该矿大倾角煤层工作面安全高效回采。

According to East Defese Coal Mine under 41 layer of-280 m mechanized coal mining face and the occurrence of coal mining conditions,through study about inclined coal seam deformation rule and pressure behavior,thus provide theoretical basis for control tunnel surrounding rock and analized the key technologies of mining bolt support,which ensured the safety mining of the high inclined seam mining.
