封闭不良钻孔导水性分析及处理方案

Poorly Closed Borehole Water Conductivity Analysis and Treatment Plan

在系统收集七五生建煤矿各时期钻探及水文地质补充勘探资料的基础上,对63-57号孔组封闭质量及导水可能性进行了分析。通过研究发现,63-57号孔组可能均未进行最终封堵,并针对性地提出了四种处理方案。研究结果对矿井安全生产及矿井水害防治具有一定的指导意义。

Based on the systematic collection of drilling and hydrogeological supplementary exploration data in each period of 75 Construction Coal Mine,the quality of the closed hole group 63-57 and the possibility of water conductance were analyzed.Through the study,it was found that the 63-57 hole group may not have the final plugging,and put forward five treatment options.The research results have certain guiding significance for mine safety production and prevention of mine water hazards.
