通过对凉水井煤矿水文地质条件分析,确定煤层开采后的突水水源主要包括第四系松散孔隙潜水和风化基岩裂隙水.采用同位素方法厘定凉水井煤矿矿井水中松散层潜水和风化基岩裂隙水所占的比例大概为4∶1,松散层潜水是凉水井煤矿突水最主要的水源.通过RFPA软件模拟预测凉水井煤矿4－2煤层开采后导水裂隙带高度为84 m.根据煤层赋存特征和开采条件,筛选出凉水井煤矿突水危险性评价因子；通过 GIS 空间分析功能对凉水井煤矿开采突水危险性进行分区评价.结果认为,麻家塔河和西沟河源头是本区突水危险性大的地区,当工作面经过这些地段时需防范突水灾害.

By the analysis of hydrogeological conditions in Liangshuij ing Coal Mine,the wa-ter inrush sources after coal mining in Liangshuijing mine were confirmed as Quaternary loose soils pore water and weathering fissure water in bedrock,and the proportion of them determined by isotope was 4∶1 ,loose soils pore water was the main water inrush source. After No. 4-2 coal seam mining in Liangshuij ing Coal Mine,the height of diversion fissure zone was simulated and predicted as 84 m by using RFPA software. According to occurrence features and mining condi-tions of coal seam,the evaluation factors of water inrush risk were selected. The GIS spatial a-nalysis function was applied for zoning and evaluation of water inrush risk,the results showed that the sources of Maj iata river and Xigou river were the high risk zones of water inrush,when mining through the zones,the controlling measures of water inrush should be adopted.
