Study on Tunnel Drilling Technology for Wulonggou Mining Area of Dulan County in Qinghai
Abstract:According to the pump blocking, hole collapse, diameter shrinkage, short footage per round trip and low core recovery appeared in the tunnel drilling of SZZK8905 which was in Wulonggou mine area in Dulan County of Qinghai with 700.20m in depth, the study on tunnel drilling was carried about rig selection, borehole structure design, coring technology in fracture zone and drilling fluid, and this hole drilling was successfully completed.
