| 摘 要： | 川南古叙矿区某矿在基建过程中多次揭露大型导水陷落柱或溶洞,导致突水事故。该矿煤系地层底板为茅口组灰岩,岩溶发育,富水性强,为煤层的直接充水含水层。依据地表水和地下水的水质特征,结合连通试验,分析了矿区地表水和地下水的补给关系,并讨论了地下水水质的成因及其对茅口组灰岩岩溶发育的影响。结果表明,地表水水质为含可溶性固体少的HCO3-Ca型水,呈中性—弱碱性;地下水水质以含可溶性固体少的SO4·HCO3-Ca型水为主,呈酸性—中性,次为含可溶性固体少的SO4-Ca型水。地表水与地下水相互补给,呈酸性的地下水水质源于硫铁矿层的溶解和氧化,对茅口组灰岩岩溶发育有强烈的促进作用。此结果对防治矿井水害具有一定的指导意义。
