摘要
8500残采皮带巷发生突水,最大水量706 m3/h,稳定水量683 m3/h,堵水期间最大水量983 m3/h。8500皮带巷的突水对矿井的安全构成严重的威胁,由于该地点水文地质条件极为复杂,为此本次应用了地面瞬变电磁法对该地点进行了勘探,根据对勘探结果的分析,进行了布孔堵水,取得了较好的效果。
November 27,2003, water inrush occurred at 8500 residual belt, the largest water flux,706 m^3/h, the stable water flux, 683 m^3/h, during water shutoff the largest water flux 983 m^3/ h. Water inrush at 8500 residual belt makes a serious threat, because of extremely complex hydrogeological conditions. After 4 years of water shutoff, nearly one billion expended on shutoff and drainage,the effect is still not ideal, based on which Xi＇an academy of sciences conduct a transient electromagnetic exploration on ground according at this site, by this data chazhuang mine disposes water shutoff pores and achieves good results.
