摘要
最近几年,在我国的回采巷道中组合锚杆支护技术得到了应用和发展,其目的旨在改善回采巷道维护状况,降低支护成本,简化回采工作面端头区维护工序,提高工作面开机率。本文总结了淮南煤矿回采巷道中采用组合锚杆支护技术取得的成功经验,在此基础上,讨论了组合锚杆支护机理,并就组合锚杆支护主要参数的确定提出了相应的看法和建议。
in the recent years truss bolting technique has been applied and developed in mining roadways, aiming at improvement of gateway support, maintenance, reduction of support costs, simplifying maintenance of support at the face ends and increased machine availability. Based on successful experience with truss bolting technique in Huainan coal mines this paper discusses the mechanism of truss and suggests the method for determining main parameters of rock trusses.
