摘要
为确保孤岛工作面安全回采,采取FLAC数值模拟分析不同影响参数(埋深、水平应力、煤层厚度及工作面宽度)条件下孤岛工作面围岩应力分布规律,模拟结果对孤岛工作面冲击地压防治具有指导意义。
In order to ensure the safe mining of the island face, the FLAC numerical simulation was used to analyze the stress distribution law of the surrounding rock of the island face under different influence parameters （depth,horizontal stress,coal seam thickness and face width）. The simulation results are instructive for the prevention and control of the rockburst of the isolated working face.
