摘　　要：本文以8101顶抽巷锚杆支护为工程背景,结合工作面所处地质环境,通过FLAC3D数值模拟确定了巷道合理永久支护参数,并运用于工程实践,现场矿压观测整条巷道掘进期间围岩位移量处于可控范围内,支护效果良好,实现巷道的安全快速掘进。Based on 8101 alley pumping bolt support as the engineering background, the geological environment of combined working face,through permanent Flac3D numerical simulation to determine the reasonable of roadway support parameter, and applied to engineeringpractice, the article observed the scene, the whole displacement of surrounding rock during drivage in manageable, supporting effect is good,the realization of roadway drivage safely and quickly.
