摘　　要：为了研究采场支承压力,运用FLAC3D软件建立工作面开采数值模拟模型,研究了工作面前支承压力分布形态及应力峰值的位置,通过与理论计算、现场实测的结果相比较,得出数值模拟、理论分析、现场实测的结果是基本一致的,提出了采场前支承压力的计算方法,对井下工作面超前支护距离设计具有借鉴意义。In order to study abutment stress in mining field,numerical simulation model of coal mining by using FLAC3D was established.Distribution of abutment stress in front of longwall and the position of stress peak appearance were studied.The results showed that the results of numerical simulation,theoretical analysis and in-situ measurement are basically the same.The method of calculation of abutment stress in front of longwall was proposed,which provides reference to advanced support distance design of longwall in deep mines.
