关于倾斜破碎矿体进路采场使用锚喷网护顶的试验研究成果和经验,包括支护参数选择、锚杆选型、锚网护帮法等方面的内容。在这一研究过程中,提出了“锚杆的锚固力与悬吊力等同”的观点、因而指出在危险地段需采取增设楔管式锚杆以防冒落的补救措施。由于锚喷网支护的灵活应用,获得了明显的经济效果和可靠的安全保障。

The experimental research results and experience on the use of the anchor sprayed screen retaining roof in the stope of tilted broken ore body, including the selection of support parameters, the selection of anchor bolts, In the course of this research, the author put forward the view that “the anchoring force and the suspending force of the anchor rod are the same”, and pointed out that the remedial measures of adding the wedge pipe anchor bolt to prevent falling in the dangerous area should be taken. Due to the flexible application of anchor net support, obvious economic effects and reliable safety guarantee have been obtained.
