摘　　要：以榆家梁矿地质条件为基础,针对43304工作面辅助运输平巷为工程背景,运用理论分析,同时结合FLAC3D数值模拟,系统地计算分析回采巷道的支护参数,提出合理的支护方案,经现场工业验证并监测研究表明:采用所提出支护方案支护后,巷道围岩能够承受开采的扰动,巷道表面变形较小,保障了工作面安全高效开采.Based on the geological conditions of Yujialiang Coal Mine, aiming at the engineering background of 43304 working face auxiliary transportation roadway, using the theoretical analysis, and combining with the numerical simulation of FLAC30, the support parameters of mining roadway are systematically calculated and reasonable support scheme is put forward. Results show that the roadway surrounding rock can bear the disturbance of mining, and the deformation of roadway surface is small, which ensures safe and efficient mining of working face.
