通过对岱庄煤矿2351工作面回采巷道支护问题的研究,提出了2351工作面回采巷道的高强度高性能预拉力锚带网支护方案和支护设计参数,并进行了现场试验。实践证明,该支护方法能够有效地控制回采巷道的围岩变形,使得工作面回采得以正常进行,满足安全生产要求,具有推广应用价值。
Through the research on roadway supporting in 2351 working face in Daizhuang Coal Mine, the supporting scheme and supporting design parameters of high strength and high performance prestressed anchorage belt for mining roadway in 2351 working face are put forward and the field tests are carried out. Practice has proved that this support method can effectively control the deformation of the surrounding rock in the mining roadway so that the working face can be recovered normally to meet the requirements of safety production and has the promotion and application value.
