     In Haoyaoerhudong gold deposit of Inner Mongolia, the intensive silicified formation is complicated with hard, brittle, broken and weathered broken stratum of sandy shale. By conventional rotary drilling, ＂slipping＂, borehole upward inclining, core plugging, less footage round, frequent fishing, short net drilling time and low efficiency often occur. These difficult problems are overcome by wire-line coring hydro-hammer with good effects.
