摘 要:针对孤岛工作面巷道围岩受两侧采空区影响,存在围岩应力大、巷道变形量大、巷道顶板支护管理难度大、影响工作面安全生产等诸多问题,拟定采用“工字钢架棚+锚网补强”支护技术,并制定工作面回采过程中上下端头及巷道超前支护技术措施。该支护技术应用后表明,其对巷道围岩起到有效控制作用,工作面实现了安全高效回采。In view of many problems such as large surrounding rock stress,large deformation of the roadway,difficult management of roadway roof support,and affecting the safe production of the working face influenced by the goaf on both sides of the roadway surrounding rock in the isolated island working face,it is proposed to adopt the support technology of"I-beam shed+anchor net reinforcement",and formulate technical measures for the advanced support of the upper and lower ends and the roadway during the mining process of the working face,whose application shows that it can effectively control the surrounding rock of the roadway,and the working face can be recovered safely and efficiently.
