我国碳酸盐岩出露面积广泛,并发育沉积、热水沉积和热液交代型等矿床,这些矿床的地下水赋存在碳酸盐岩的溶隙、溶管、溶管系和溶管网中,使得地下水运动复杂化。研究区矿床赋存在碳酸盐岩中,地下水为松散堆积层孔隙水、基岩裂隙水和碳酸盐岩溶水;不同类型水渗透系数不一,矿坑涌水量实测值为743.00 m3/h,采用数值化模拟矿坑地下水变化,获得深部开采时的地下水变化趋势,并提出突水防控对策。

Outcrop area of carbonate rocks in China is widely distributed and there are deposits like sedimenta-ry deposits,hydrothermal sedimentary deposits,and hydrothermal metasomatic deposits.Groundwater within these deposits occurs in solution crack,pipe,pipe system and pipe network,hence the movement of groundwater is complicated.Deposits in research area occur in carbonate rocks,and the groundwater is pore water in loose accumulative formation,fissure water in bedrock and karst water in carbonate rock.The per-meability coefficient of different types of water is different from each other,and the observed value of mine water yield is 743.00m3/h.Numerical modeling is used to simulate the change of mine groundwater and to acquire the change trend of groundwater during deep mining.At last,countermeasures of water bursting control are proposed.
