潜孔锤技术在三道庄钼矿采空区探测中的应用

Application of Down-hole Hammer Technology for Survey in Worked-out Area of Molybdenum Mine

摘要:

结合高风压潜孔锤钻进技术在洛阳栾川钼业集团三道庄钼矿区采空区探测中的应用，介绍了高风压潜孔锤技术钻进塌陷区、穿越采空区施工技术。应用高风压潜孔锤钻进技术在洛钼集团三道庄钼矿进行采空区探测，摸索出了相应的钻进工艺方法，大幅度提高了成孔率，对同类型矿山采空区勘探具有参考意义。

Abstract:

According to the application of high-air pressure down-hole hammer drilling technology in worked-out area of molybdenum mine, the paper introduced the subsidence area drilling with high-air pressure down-hole hammer and crossing subsidence area construction technology. By the survey in worked-out area of molybdenum mine with high-air pressure down-hole hammer drilling technology, relative drilling technological methods were found out and success rate of borehole was largely increased.
