Abstract

Taking Yushenfu mining coal area in northern Shaanxi as the research area, the geological structure of the whole coal-bearing strata was selected as the research object. In this paper, 80 structural models of overburden strata were constructed according to the main geological structure of the mining area. The ratio of rock to soil, coal mining depth and sandstone layer number were taken as the three factors influencing the stability of overburden strata. Based on the key strata theory, three influencing factors were analyzed by mechanical method and multiple regression analysis in order to find the most influential factors of overburden stability.
