定向钻进技术在双龙煤矿采空区探测中的应用

Application of Directional Drilling Technology in Detecting Goaf in Shuanglong Coal Mine

双龙煤矿采掘过程中存在小煤窑破坏,为了精准探测出小煤窑破坏区域范围,为双龙煤矿布置采面提供准确地质资料,通过采用定向钻进技术,在回风大巷施工6个定向探测钻孔,快速高效探测出小煤窑破坏区域范围。结果表明:定向钻进技术用于采空区探测技术可行,且具有快速高效、探测精度高的优点。

There are small coal mines in the process of mining of Shuanglong Coal Mine. In order to accurately detect the damage area of small coal mines in Shuanglong Coal Mine and provide accurate geological data for Shuanglong Coal Mine, six directional drilling holes are constructed in the return airway by using directional drilling technology to rapidly and efficiently detect damage area of small coal mine. The results show that the directional drilling technology for goaf detection is feasible, and it has the advantages of fast and high efficiency and high precision.
