东保卫煤矿西翼风井快速施工技术应用
|
摘要
在东保卫煤矿西翼风井井筒施工中,为充分发挥机械化配套设备能力,推广应用伞钻凿眼深孔爆破、中心回转抓岩机装岩等凿井技术,采用了地面预注浆法对井筒裂隙岩层中的水进行封堵,保证了正常井筒掘砌施工,实现了连续5个月进尺破百米,当年开工当年掘砌到底。
During the west wing ventilation shaft construction in Dongbaowei coal mine, building combined work can fully make the ability of mechanization collecation equipment,extend new technology of umbellar borer holing and deep hole blasting and sinking by center rotating grab. Using ground pre-grouting technique,to be plugging formation fracture, provide a guarantee for the normal construction. For five consecutive months continuously breach 100 m,the completion of the project started and completed within a year.
