摘　　要：杨河煤业-300水平井底巷道受采深影响,围岩呈现工程软岩特性,同时受构造影响,围岩层理、节理极为发育,尤其是主石门附近的大断面多交岔点巷道,应力集中,采用常规锚网支护或棚式支护已难以有效地控制巷道的强烈变形,保证巷道的正常使用。本文在分析-300主石门巷道支护失稳的基础上,提出高强稳定型锚注-围岩-支架耦合支护方案,并在该段巷道成功应用,取得较好的效果。The roadway of Yanghe coalmine located at-300 level is influenced by the depth,and the surround⁃ing rock with the engineering soft rock characteristics,and as well as affected by the structure,surround rock strata and the joint development,especially the roadway with the large section and multiple-point crossover near the main cross-cut that the coefficient of stress concentration is much more larger.The conventional anchor net supporting or shed support is difficult to control the strong deformation of roadway effectively,and ensure the nor⁃mal use of roadway.Based on the analysis of the instability of the main cross-cut,this paper puts forward the high strength and stable coupling support scheme of anchor injection-surrounding rock-support,which has been successfully applied in the mine and achieved good results.
