| Abstract: | Different natures and compositions of overlying rocks have a critical impact on the overburden movement and destruction and the law of the working face's overburden movement and destruction is the basis of the strata control.Using RFPA2D to simulate the short wall mining with different overlying rocks in Shendong,and then analyzing and comparing the impact of different natures and compositions of overlying rocks to the movement and destruction of the overburden.Representing the law of the destruction and mo... |
