摘　　要：平顶山八矿开采二水平二1煤受底板高温高压寒灰岩溶水的突水威胁,水温50~52℃,水质属于富含偏硅酸和锶,属于适合饮用的天然矿泉水。因突水系数超过临界值,所以需要疏水降压。八矿将疏放寒灰水与地面工业广场的生活用水结合起来,建成了地热水综合利用工程,既消除了岩溶水对井下采煤的水害影响,每年也为矿井节省数百万元的燃煤、排水等费用。The second level 21 coal mining in Pingdingshan No.8 Mine is threatened by the water inrush of the cold ash karst water under high temperature and high pressure,water temperature 50~52℃,water quality is rich in metasilicic acid and strontium and suitable for drinking natural mineral water,because the water inrush coefficient exceeds the critical value,hydrophobic depressurization is required.Pingdingshan No.8 Mine combines the drainage of cold ash water with the domestic water of the ground industrial square,the comprehensive utilization project of geothermal water has been completed,the effect of karst water on underground coal mining has been eliminated,it also saves millions of dollars in coal burning and drainage costs for the mine every year.
