Abstract:The paper introduced 3 deep holes construction in Zhuxi mining area about the drilling formation,drilling equipment,borehole structure,bit application,drill string lifting,washing fluid application,wall protection lost circulation control and casing situation.Analysis and summery emphasized the drilling technologies of borehole structure,bit application and wall protection lost circulation control.Some suggestions were made for deep hole construction on drilling equipment matching;outside bit diameter increasing;drilling efficiency improvement;hole deviation,especially azimuth out of tolerance and karst cave.
Keywords:deep hole drilling  wire-line coring  diamond bit  technology  Zhuxi mining area
