谈甘肃—东洞沟金矿区斜孔施工技术

Introduction to Gansu—East oblique hole groove gold mining area construction technology

以肃北县盐池弯乡东洞沟和西洞沟金矿破碎带地层为研究对象,结合ZK1202钻孔斜孔钻探施工技术的应用情况,着重分析了较厚破碎带地层中泥浆的应用和泥浆严重漏失时的钻进方法及护壁堵漏措施,总结了绳索取心钻探在金属矿破碎带地层中采取的技术措施和保证钻孔施工技术指标应注意的事项。

Taking Subei county bending of salt pond township hole groove East and West hole fracture zone formation of gold mine as research object, combining ZK1202 drilling inclined hole drilling technology application, this paper analyzes the thicker in the fracture zone formation of serious leakage in the application of the mud and mud drilling method and plugging and protecting measures, summed up the rope coting drilling technical measures applied in the metal fracture zone formation and ensure drilling construction specifications that should be paid attention to matters.
