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
