Abstract

Taking the project field as background, the paper studied the supporting technology of mining gateway with weak surrounding rock in 3-1 shallow seam mining of a coal mine, and solved problems of mining gateway slide and roof deformation and failure. The shortage of original supporting system was simulated and analyzed, and by theoretical analysis and field investigation, a support optimizing program was put forward, which was adding the strength and length of rock bolts, and using the combined support system with rock bolts, cables, nets, and rebar trays, and by using FLAC3D numerical simulation software, the rationality of support optimizing program was analyzed. Field test showed that the support optimizing program can guaran-tee compound mining face with shallow buried depth producing safely and efficiently, and the paper pro-vided a basis for the supporting technology of mining gateway in mine working faces of the coal mine and mines with similar condition.
