为了解断层破碎带的含水性，一九六四年在闸河煤田先后打了三个抽水孔，一个观测孔，要求用清水钻进，终孔口径不小于91毫米。施工中，由于断层影响，极为破碎，孔壁坍塌严重，无法钻进。这个钻进技术问题，不解决，不仅大大影响钻进效率，更重要的是不能取得水文地质资料，影响地质勘探报告。为解决这一关键问题，在缺乏资料和经验的情况下，采用了以快速钻进和跟管钻进相 In 1964, three pumping holes and one observation hole were drilled in Zhahe coalfield in order to understand the water content of the fractured zone. Drilling was required with clear water and the diameter of the final hole was not less than 91 mm. Construction, due to the fault, extremely broken, hole wall collapse serious, unable to drill. This drilling technology problem, not solved, not only greatly affects the drilling efficiency, but more importantly, it can not obtain hydrological data and affect the geological exploration report. In order to solve this crucial issue, in the absence of information and experience, a rapid drilling and follow-up phase
