绳索取心液动锤在浩尧尔忽洞金矿复杂地层中的应用

Application of Wire-line Coring Hydro-hammer in Complex Formation of Haoyaoerhudong Gold Deposit

摘要:

内蒙古太平矿业浩尧尔忽洞金矿地层复杂,多强硅化的硬、脆、碎地层及部分砂质页岩等风化破碎地层，常规回转钻进地层打滑，钻孔上漂，岩心堵塞，回次进尺少，打捞频繁，纯钻进时间少，台月效率低。采用绳索取心液动锤钻进工艺,克服了上述问题，取得了良好的效果。

Abstract:

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.
