摘要
阳方口矿业集团公司下设程家沟矿、石湖矿,石湖矿主采2#煤层为复合顶板,程家沟矿主采煤层5#层为典型的“三软”煤层,均为困难条件下的煤巷锚杆支护。通过总结近年来煤巷锚杆支护的工程实践经验和研究结果,提出了困难条件下煤巷锚杆支护的顶板控制技术。
The Yangfangkou Coal Mining Company has Shihu Mine and Chengjiagou Mine, in which the former used composite plates in its main No.2 layer and the latter has typical ＂three - soft＂ layer in its main No.5 layer, and both used anchor- bar supporting technique in hard situations. After summarizing the working experiences and study results, this article has proposed a plate supporting technique with anchor bars in coal tunnels.
