摘要
以莒山煤矿ZF305综放工作面回风巷道为工程背景,分析了巷道的地质条件及破坏情况,并通过理论分析巷道围岩破坏深度及锚杆支护参数给出了巷道支护方案。经工程实践验证了该支护方案的可行性,巷道围岩得到了有效控制,具有良好的应用效果。
Taking the return air roadway of ZF305 fully mechanized caving face in Jushan Coal Mine as the engineering background,the geological conditions and destruction of the roadway are analyzed firstly,then the destruction depth of the surrounding rock and the parameters of bolt support are analyzed theoretically,and the roadway support scheme is given.Finally,the validation research is carried out through engineering practice.The practice proved its feasibility,and surrounding rock of the roadway has been effectively controlled and has good application effect.
