七十年代以来,锚喷支护在我国发展速度极快。1978年全国有关行业曾在淮北朱仙庄矿井召开了光爆锚喷现场会议,会上介绍了锚喷支护的优越性,施工单位也提出了实现全矿井锚喷化的奋斗目标。笔者拟从该矿井井巷验收工作实践,来分析一下关于锚喷支护的适应性和经济性问题,使它在今后能发挥更好的经济效益。 一、锚喷支护的适应性 Since the seventies, anchor spray support rapid development in our country. In 1978, relevant industries in the country held a spot explosion anchor spraying meeting at the Zhu Xianzhuang mine in Huaibei, introducing the superiority of anchor and shotcrete support. The construction unit also proposed the goal of realizing anchor spray in the whole mine. I intend to mine from the mine acceptance work practices to analyze the anchor spray support adaptability and economic problems, so that it can play in the future better economic efficiency. First, anchor spray support adaptability
