许疃矿南翼运输大巷地质条件复杂且受高应力作用,巷道变形严重并难以趋于稳定,以往采用的U形钢强支等支护方法均不能从根本上解决问题。通过数值模拟及工程实践,提出了“锚杆与金属支架相互增强”原理,采用此方法支护后,取得了预期的效果,能够有效地抑制巷道的变形并且经济效益显著。 Due to the complex geological conditions and the high stress, the roadway deformation is serious and difficult to stabilize. The conventional support methods such as U-shaped steel strong support can not fundamentally solve the problem. Through the numerical simulation and engineering practice, the principle of mutual reinforcement of anchor rod and metal support is put forward. After this method is adopted, the expected effect is achieved, the deformation of the roadway can be effectively suppressed and the economic benefit is remarkable.
