佳县上高寨普查勘探区上部为第四系黄土堆积而成，基岩主要是由黄褐色洛河砂岩以及灰白色泥质砂岩、灰褐色泥岩等构成，岩石硬度比较小，裂隙、破碎情况比较突出，导致钻探施工难度较大。在总结用普通取心钻进时出现的问题基础上，介绍了绳索取心钻进的钻进工艺技术的特点和应用细节。结果表明，采用绳索取心钻进工艺技术，增大了纯钻进时间，降低劳动强度，提高钻进质量和岩、煤心采取率，降低了钻探成本。最后经过测算普通钻进工艺的单位成本为520.53元/m，绳索取心钻进工艺的单位成本为310.16元/m，单位成本降低了40％。对普及绳索取心钻探工艺在煤田中深孔钻进勘探具有重要的指导意义。

Upper part strata in the Shanggaozhai prospecting area have Quaternary accumulated loess, bedrock mainly yellowish brown Luohe sandstone and grayish white argillaceous sandstone, grayish brown mudstone. Rock hardness is relatively small, fractures and fragmentation status rather serious, thus caused drilling operation difficult. Based on summarization of problems appeared in common core drilling, introduced wire-line core drilling technological peculiarity and application details. The result has shown that the wire-line core drilling technology can increase penetrating time, lower down labor intensity, improve drilling quality, rock and coal core re?covery, and reduce the cost. Finally, after estimation, the common drilling technology unit cost is 520.23 RMB Yuan/m, while wire-line core drilling is 310.16 RMB Yuan/m, have reduced 40%. Thus the technology has guiding significance in popularization of wire-line core drilling in coalfield deep borehole drilling.
