摘　　要：禾草沟二号煤矿主采煤层为3#煤层,巷道围岩破碎,围岩层状节理裂隙发育,顶、底板皆为粉砂质泥岩。禾二矿在大变形软岩巷道支护中仍采用传统巷道支护方法,对禾二矿的安全生产及接续构成了威胁。以实验室实验、理论分析及现场工业试验为基础,采用大变形软岩巷道耦合支护技术,取得良好效果。The main coal seam of in Hecaogou No.2 coal mine is No. 3 coal seam,roadway rock breaking,surrounding rock stratified joint fissure development. Hecaogou No.2 mine is still using traditional roadway support method in large soft rock roadway support, the safety of Hecaogou No.2 mine and the formation of a threat. Based on laboratory experiments, theoretical analysis and field industrial tests,used coupling support technology with large deformation soft rock roadway,get good results.
