摘　　要：针对2201运输平巷所面临的支护难题,在分析其围岩破坏机理的基础上,结合本矿巷道支护经验及矿压显现具体情况,制定了3条巷道支护基本原则及注浆架棚喷浆协同支护方案,成功进行了工业性试验,并经后期矿压观测分析,证实了支护方案的有效性及合理性。In view of the supporting problems faced by 2201 transport roadway, based on the analysis of the failure mechanism of surrounding rock, combined with the roadway support experience and the specific situation of mine pressure, three basic principles of roadway support and grouting frame shed shotcrete collaborative support scheme are formulated, and the industrial test is successfully carried out. After the later mine pressure observation and analysis, the effectiveness and rationality of the support scheme are verified, and the expected safety benefits and technical and economic benefits are realized.
