锚杆——钢带——网组合锚杆支护是一种重要的回采巷道支护方式,也是矿井实现高产高效的重要措施之一。它在国内煤矿中已广泛推广应用,收到显著的技术经济效果。在组合锚杆支护中,W型钢带是关键的技术构件。它将单根锚杆联合起来组成一个整体支承结构,显著地提高锚杆支护的整体效果。新汶矿务局在良庄煤矿5211高档普采工作面回风巷进行树脂锚-W型钢带-金属网组合锚杆支护的井下试验和应用。这种组合锚杆支护形式经受信了从巷道开掘到回采工作面结束整个生产过程矿压显现的考验,取得了巨大的技术经济效益。
Bolting - strip - net combination of bolt support is an important support roadway mining, but also mine to achieve high yield and efficiency of one of the important measures. It has been widely used in domestic coal mines, received significant technical and economic results. In the combination of bolt support, W-strip is the key technical components. It combines a single anchor to form a one-piece support structure that significantly increases the overall effectiveness of bolt support. Xinwen Mining Bureau in Liangzhuang Coal Mine 5211 high-grade universal mining face return airway resin anchor-W-steel mesh combined with bolt support underground tests and applications. This combination of bolt support form has been convinced from the roadway dig to the mining face the end of the entire production process of underground pressure test, and achieved tremendous technical and economic benefits.
