Abstract

Taking the coal-bearing strata with fine sandstone-siltstone interbedded structure as the example, 12 different types of stratified structure models were constructed with the quantity of rock strata, rock-soil ratio and mining depth as the variables. Based on the theory of key stratum, the stability of overburden structure with different variables is analyzed by geological method, mechanics method and regression analysis method. The influence of these three factors on mining subsidence is revealed.
