摘要: 防止松散层水溃入矿井是祁东煤矿的重点防治水对象,正确判断出水点和出水水源是解决问题的关键。文章通过对松散层水和煤系地层砂岩水混合效应的水文地球化学研究,利用对比分析方法找出变化明显的特征离子(Ca2+、Mg2+、SO42-和HCO3-),将其作为水质监测的重点对象,从而判断突水水源,为建立防止松散层水溃入矿井的预警系统提供可靠依据。Abstract: Prevention of groundwater in unconsolidated sediments from bursting into the coal mine is the main objective of water control in the Qidong coal mine.The key to the problem is to locate correctly the exit points of water and the sources of water.Hydrogeochemical research on the mixture effect of groundwater from the unconsolidated sediments and groundwater from the coal-bearing sandstones is carried out.The characteristic ions of an obvious change are found out by comparison and analysis methods...
