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743.00m3/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。
Carbonate rocks in our country have a wide area of exposure and are characterized by sediments, hydrothermal sediments and hydrothermal replacement sediments. The groundwater of these deposits is found in carbonate reservoirs, Groundwater movement complicates. Deposits in the study area are found in carbonate rocks. The groundwater is loosely accumulated pore water, bedrock fissure water and carbonate rock water. The permeability coefficients of different types of water are different. The measured value of mine gushing water is 743.00m3 / h. Numerical simulation of groundwater changes in mines to obtain the trend of groundwater changes in deep mining, and put forward water inrush prevention and control measures.
