摘　　要：高应力条件下的松软破碎岩层巷道掘进与支护，是丰山铜矿难采矿体首先需要解决的关键技术。试验研究采用的小断面超前光面爆破掘进新工艺；喷、浇、锚、网与壁后注浆联合支护新技术，有效地解决了这一技术难题，为丰山铜矿南缘面临报损的难采矿体开采创造了条件。A new technology of both smallsection advance drifting based on smoothsurface blasting and combined supporting with shotcreting,pouring,bolting,wire mesh and back grouting was developed.This difficult technical problem on drifting and supporting in a soft and crumbly strata in a high stress was settled effectively to provide a mining possibility for Fengshan Copper Mines difficult orebody which is faced with abandonment.
