摘　　要：分析了深部煤层巷道的围岩变形特点及采用刚柔二次耦合支护的理论依据 ,据此进行了锚杆与锚索支护参数确定 ,通过现场实测 ,巷道围岩变形得到了有效控制 。Deformation characteristics of surrounding rock in deep coal gate was studied, as well as theoretical gist of rigid yielding secondary coupling supporting. Parameters of bolt supporting and cable anchor was determined. Deformation of surrounding rock was controlled effectively and good control effect was also gained.
