摘要
大倾角软煤层采用放顶煤开采会面临一定的困难,以该工作面放顶煤开采为研究对象,采用离散元法研究其工作面矿压规律,为此种采煤方法的支护设计提供理论依据。
Large angle soft coal seam with caving mining faces some difficulties,on the works surface of top coal caving mining as the research object by using discrete element method to study the working face of mine pressure law,provide the basis for the supporting design theory for this mining methond.
