Abstract: In view of the dynamic disasters such as coal wall slabs and roof caving during the working face passing through the fault, combined with the coal seam geological conditions of the W1319 working face of Gaohe coal mine, using the theoretical analysis, UDEC numerical simulation combined with field measurement method, such as comprehensive research in the process of working face roof caving method management through the fault movement of overburden rock damage and the stress distribution characteristics.The results show that the stress in the steady state is affected by the fault, and the stress increases abnormally.After the working face pushes through the fault, the stope stress is greatly weakened and the vertical displacement of the overburden on both sides of the fault is obviously different.The propagation of the fault corresponding stress and the development of the plastic zone are obviously blocked.The fully mechanized mining face undergoes the stress stationary stage, the stress anomaly increases stage and the stress decreasing stage, and the fault has disappeared into the stress stationary stage again after the stress reduction stage.The results of numerical simulation are consistent with the result of field measurement.The research results provide theoretical basis and technical guidance for the safe and efficient production of fully mechanized mining face during fault crossing.
