摘要
双龙煤矿 200 工作面区域水害危险性不详,为确定区域内水害危险性,采用物探结合钻探的方法进行综合研究.物探采用高密度电法勘探,确定低阻异常区 9 处,共计 4.75×104 m2;采用钻探进行水量验证,确定区域水文地质类型为以裂隙充水为主的简单型.通过综合勘探可知,200 工作面区域水害危险性小、水量小.
Abstract
The water hazard in 200 working face of Shuanglong Coal Mine was unknown.In order to determine the water hazard in the area,the method of geophysical exploration combined with drilling was applied for comprehensive study.High-density electrical exploration was used to determine 9 low-resistivity anomaly areas,with a total of 4.75×104 m2.The water quantity was verified by drilling,and the regional hydrogeological type was determined to be simple type dominated by fissure water filling.Through comprehensive exploration,it can be seen that the water damage risk and water quantity in the 200 working face area were small.
