In this paper, Yushenfu mining area is taken as an example. On the basis of analysis and research of formation mechanism of mining subsidence, using principal component analysis and grey correlation analysis method, factors which affect the damage degree of mining subsidence have been selected. It is determined that disturbance coefficient, the ratio of width to depth, comprehensive hardness of overlying...
Considering YuShenfu coal mining area, this paper uses the Gray correlation analysis method to analyze and select the 7 major factors which come from two aspects that are geological occurrence condition and coal mining design condition, on the basis of analyzing the formation mechanism of mining subsidence in the study area. And the five of seven which are disturbance coefficient, width-depth ratio,...
