Abstract

As a widely used finite difference software in coal mine research, FLAC3D is applied with to simulate the deforming course of coal body around spraying hole induced by waterpower. The results are appealing and instructive for optimization of gas drainage holes in outburst mine. Two core simulating distribution rules on stress field and displacement field issued in this paper are both verified on site in Qinan Coal Mine of Huaibei Group. The methane drainage monitoring data indicate that spraying hole through beds induced by waterpower is beneficial to improve the drainage effect. Therefore, the paper provides technicians on gas comprehensive control with new bases and practical reference.
