煤矿井筒检查孔位置的确定和施工工艺,直接影响所获得的地质水文资料的可靠性,因此井筒检查孔位置的选择,一定要考虑其代表性和主副井筒所处场地的地质和水文地质条件,做到合理布孔,正确施工。本文从水文地质的角度出发,着重探讨了井筒检查孔的孔位布置、施工要求以及涌水量计算中应考虑的问题。井筒检查孔的布置与施工,不仅仅是一个在井筒附近施工一个地质钻孔的问题,而是事关而后施工及安全生产的大问题。因而,应对井筒邻近水文地质资料进行认真的分析,根据井筒所在位置的具体的水文地质条件科学合理地布置孔位,编制钻孔设计,重视水文地质资料提取,以确保井筒开凿有较可靠的水文地质资料。
The determination of coal well bore inspection hole location and construction technology have a direct impact on the reliability of the obtained hydrological data. Therefore, the location of borehole inspection holes must be selected according to their representativeness and the geological and hydrogeological conditions , Do a reasonable hole, the correct construction. In this paper, from the perspective of hydrogeology, this paper focuses on the hole location of borehole inspection holes, construction requirements and calculation of water inflow should be considered. The layout and construction of the wellbore inspection hole is not only a matter of constructing a geological borehole near the wellbore, but a major issue related to construction and safety production. Therefore, the wellbore adjacent hydrogeological data should be carefully analyzed, the hole positions should be scientifically and reasonably arranged according to the specific hydrogeological conditions of the wellbore location, the drilling design should be drawn up, and the hydrogeological data extraction should be emphasized to ensure that the wellbore is drilled with more reliable hydrology Geological information.
