宣下煤田煤系基底蓟县系白云岩水文地质研究
|
摘要
为了进一步查清张家口宣东矿基底含水层水文地质条件,评价煤层基底含水层水威胁程度,为Ⅴ2煤层的安全带压开采提供指导性防治水途径,在宣下井田布置施工了5个水文钻井,通过抽水试验、水质分析、水文分析等研究方法,清晰地探明了基底蓟县系白云岩含水层情况。
In order to further find out Zhangjiakou XuanDong ore basal aquifer hydrogeological conditions, the evaluation of coal seam water threat level, basal aquifer for V2 seat belt pressure of coal seam mining provides guidance to prevent and control water way, decorate in the mission of the field construction of the five hydrological well drilling, by pumping test, water quality, hydrological analysis and other research methods, clearly proved the basal Ji County system of dolomite aquifer.
