| 摘 要： | 综合利用马坑矿区积累的水位、水温资料,结合前期对矿区水文地质条件的认识,查明了矿区岩溶水在疏干条件下的补给的变化特征。矿区岩溶含水层以石炭系船山组至二叠系栖霞组灰岩为主,大气降水为其主要补给来源。矿区开采过程中由于矿山采石场开采灰岩造成的溶洞出露地表、采空塌陷裂隙、第四系扰动及沟谷堵塞等使大气降水入渗补给量增大;断层破碎带使分布于灰岩含水层上部的二叠系文笔山组泥质砂岩地层具有了良好的含水性及导水性,致使其上部加福组砂岩裂隙水通过小娘坑断层及F3断层等破碎带补给岩溶水;溪马河河水沿河床与F1断层交汇段渗漏补给岩溶水;深部花岗岩低温热水也沿F1及F10断层破碎带进入矿坑。

| Abstract: | On the basis of ascertained hydrogeology conditions, the regime of karst groundwater recharge under dewatering conditions in mining area is found out by means of groundwater table and water temperature data.The aquifer, recharged mainly by precipitation infiltrating water, is composed of the Chuanshan group limestone in the Carboniferous system and the Qixia group limestone in the Permian system. The infiltrating water increased because of the mining activity that exposing some caves, leading fissures by collapse in goaf, disturbing of the Quaternary system sediments and blocking of gullies. Fault fracture zone turns the Wenbishan group argillaceous sandstone of the Permian system into aquifer with good aquosity and transmissibility, which leading to the fissure water in the overlying Jiafu group sandstone recharging the karst groundwater via the Xiaoniangkeng fault and F3 fault. The river water in the Ximahe recharges karst groundwater by seepage along the cross part of the riverbed and the F1 fault. The hypothermia water in the deep granite also entering the pit along the F1 and F10 faults. |
