Abstract

In this paper,the SFPA^2D(Stratum Failure Process Analysis) software is used to simulate the movement rule of overlying strata when the shallow coal seam was extracted in the Huojitu Mine of Shenfu-Dongsheng mine area.According to simulation results,along with working face being advanced,the failure processes and features,and weighting of overlying strata,were analyzed.
