摘要
煤矿井田内岩溶陷落柱是制约煤矿安全开采的瓶颈,采掘工作面常因陷落柱作为含水层的天然导水通道而引发突水事故。为了避免岩溶陷落柱影响采掘工作面安全生产,查清陷落柱的导水性是非常有必要的。大阳煤矿经三维地震勘探发现,3307备采工作面发育2个陷落柱XT9(长轴54 m,短轴45 m),XT2(长轴270 m,短轴94 m),为了尽早布置采掘任务,采用地面瞬变电磁法对岩溶陷落柱导水性进行了探测,取得了良好的效果,有效保障了工作面的安全回采。
The karst collapse column in the coal mine field is the bottleneck restricting the safe mining of coal mines.The mining face often causes water inrush accidents due to the collapse column as the water-conducting channel of the aquifer.In order to avoid the karst collapse column affecting the safe production of the mining face,it is very necessary to find out the water conductivity of the collapsed column.Three-dimensional seismic exploration in Dayang Coal Mine found that there are two collapsed columns XT9(long axis 54 m,short axis 45 m)and XT2(long axis 270 m,short axis 94 m).In order to arrange the mining task as soon as possible,the ground transient electromagnetic method was used to detect the water conductivity of karst collapse column,which had achieved good results and effectively guaranteed the safe mining of the working face.
