为了超远距离准确探测出煤层走势、采空区、陷落柱、断层等异常地质构造,消除异常地质构造给煤矿生产带来的安全隐患。通过对煤矿井下定向钻进技术特点的分析,得出定向钻进技术在煤矿井下地质勘探应用中具有精度高、距离长和施工灵活性等优点,根据矿井地质勘探施工要求,研究其在矿井地质勘探中施工方法,并通过现场应用案例证实了定向钻进技术在煤矿井下长距离、高精度地质勘探中的技术优越性。
In order to accurately detect the coal seam trend, goaf, collapse column, faults and other anomalous geological structures in ultra-long distance, the potential safety hazard caused by abnormal geological structure to coal mine production is eliminated. Through the analysis of the characteristics of directional drilling technology in coal mine, it is concluded that the directional drilling technology has the advantages of high precision, long distance and construction flexibility in the geological prospecting and application of coal mine. According to the requirements of mine geological exploration and construction, Exploration and construction methods, and through field application cases confirmed the directional superiority of directional drilling technology in coal mine long-distance, high-precision geological exploration.
