陆良石槽河煤矿充水因素及漏水量估算

摘要

石槽河煤矿位于断陷盆地中，可采煤层M3位于最低排泄基准面之下，无法自流排水，矿坑水主要来自煤层顶板、河水渗流及降水渗入。计算获得矿井漏水量为4472m3／d（正常）和6411m3／d雨季。%The Shicaohe coal mine is in a fault basin. Because the exploitable coal bed M3 is below the lowest drainage base level, the water can＇t be drained off itself. The water in the shaft originates mainly from the top of coal bed, seepage of river water and precipitation. According to the calculation of large well method, seepage of river water and precipitation, the water yield of shaft is 4472 m3/d （usual） or 6411 m3/d （raining season）.
