摘要
随着浅部可采资源越来越少,对老矿山进行深部和外围资源勘探的需求越来越迫切,坑道勘探是在老矿区进行深部资源勘探的一个捷径。结合太白县某金矿坑道勘探的钻孔需求,采用了绳索取心水平钻进工艺,合理选择钻机、钻具及辅助装备,完成了勘探工作,为国内采用水平孔绳索取心钻进工艺施工坑道勘探钻孔提供参考。
The deep and peripheral resource exploration in old mine has been much more urgent as the shallow available resource is less and less, now the tunnel exploration is a shortcut for deep resource exploration in old mine. According to the tunnel exploration drilling conditions of a gold mine in Taibai County, horizontal wire-line coring technology is adopted with rational selection of drilling rig, drilling tools and auxiliary equipments to finish the exploration work, which can be a reference for using horizontal wire-line coring technology in tunnel exploration drilling in China.
