    摘要:

    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。

    Abstract:

    Achievemenets and experiences in boiting-shotcreting-mat support for the entrance stope in the dip fractured orebody are presented in the paper, including selection of support perameters and bolt types, and rib protection with bolts/mat. During the research process, the view that anchoring force differs from its hanging force is put forward. Based on this, we-dged-tube bolts have been used as a remedy in dangerous areas to prevent rock fall. This uniqe support system has yielded remarkable economic profits and offered reliable safety because of its flexibility.
