摘要
Abstract
This paper mainly discussed the vertical stress, the rock plastic zone laws and the working face hydraulic support force using FALC3D numerical simulation method when a working face advanced the different distance. The peak value of the vertical stress appears in 6m of the front of the coal wall, and the peak value of the vertical stress is 23 to 28.1MPa. Mining influence is in the range of 4 ~ 8m, the maximum resistance of the support is about 14000kN. This paper provides a reliable reference for the safe and efficient mining of thick coal seam, which is of guiding significance to the production.关键词
