Abstract

According to the in situ mining and geological conditions of steep coal seam mining, numerical studies are carried out for clarifying the ground subsidence due to coal extraction. Based on the comparative analysis of the results, the basic features of strata movement and ground surface subsidence due to steep coal seam mining are obtained. The maximum displacement of overburden strata develops along the normal direction of steep coal seam and mainly controlled by one or several key strata. These results are of tutorial impart for practical mining and governing mitigation of subsidence hazards.
