大钻窝硐室施工技术在玻利维亚矿山的研究与应用

Research and application of large chamber operation technology in Bolivia mines

针对玻利维亚矿山大钻窝硐室(指底部宽度超过5m,高超过7m)的施工技术难题,结合玻利维亚经济条件、矿山施工工艺、工人技能水平及国内大钻窝硐室的施工经验,进行了大钻窝硐室施工技术的研究,并将该施工方法成功应用于某矿山大钻窝硐室的施工,安全高效地完成了该矿山所有大钻窝硐室的施工,为以后该矿山其他工程施工及相似矿山的施工提供了经验。

In order to solve the operating technical difficulties of large chamber,bottom width exceeds 5 m,height exceeds 7 m in the Bolivian mines,combining Bolivia＇s economic conditions,mine operation techniques,workers＇skill levels and the operation experience of domestic large chambers,a study was conducted on the operation technology of large chambers.The operation method was successfully applied to the operation of a large chamber in a mine,and the operation of all large chambers in the mine was completed safely and efficiently.It also provides an example for other operation projects and similar mines.
