Application of Wire-line Coring Technology in Horizontal Borehole for Exploration in Gold Mine Tunnel

Abstract:

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.
