摘要为获取高强度开采条件下煤体采动裂隙，以天地王坡矿3207工作面为背景，采用钻孔窥视法、测线法和测窗法等综合手段进行煤体采动裂隙现场实测研究。在此基础上，结合COMSOL Multiphysics软件研究煤体采动裂隙场对采动应力分布、煤层瓦斯压力的影响；探讨瓦斯压力与采动裂隙分布之间关系，并分析采动裂隙条件下抽放孔的合理布置方式。

Abstract：The borehole camera method，single scan line method and sampling window method are used to study the mining-induced fracture field under high-strength mining conditions，based on the 3207 workface in Tiandi Wangpo coalmine. On this basis，the influences of mining-induced coal fracture field on mining-induced stress and gas pressure distribution are investigated by using COMSOL Multiphysics software. The relationship of gas pressure with mining-induced fracture distribution is discussed；and the reasonable layout of drilling holes under mining-induced fracture conditions is also analyzed.

Key words： mining engineering mining-induced coal fracture field measurement gas drainage numerical simulation
