| 摘 要： | 采用FLAC-3D软件模拟了在煤层开采过程中采场支承压力的动态变化、依据数值模拟结果，拟合了支承压力集中系数与工作面推进距离的关系曲线。通过对比分析模拟结果，得出了工作面推进距离和长度及煤层的厚度和埋藏深度对支承压力集中系数和支承压力峰值点距工作面距离的影响程度，进而总结出采场支承压力分布规律，这些规律可为采场巷道维护、防治煤与瓦斯突出和顶煤可放性评价提供依据。

| Abstract: | The dynamic movement of the working face abutment pressure during the coal mining is simulated with the FLAC-3D simulating software.And the curve about the relation between the abutment pressure concentrated coefficient and working face advanced distance is fitted according the simulating results.Contrasting simulation results,the relationships between abutment pressure concentrated coefficient and the distance which distant S meter from the rip with factors such as working face advanced distance,face length,coal seam thickness and buried depth are obtained.Then gained the attribution laws of abutment pressure.Those laws can offer gist for roadway maintenance,coal and gas outburst and caving evaluation of top coal. |

| Keywords: | abutment pressure numerical simulation face length face advanced distance thickness of coal |
