摘　　要：堆场存在两个渗漏系统：一是堆场东侧的890m标高以上的采空区渗漏，为堆场废液通过采空区顶板的白云岩含水层渗透至采空区，分别向800平硐及745风巷排泄溢出；二是堆场的F10-F6断层带渗漏，堆场废液经断层带白云岩含水层的渗透，向北径流排泄于S6泉。根据水质监测资料，采用一维解析方法及统计方法求取的水动力弥散参数表明，裂隙孔隙介质污染质运移具有浓度叠加的特征，渗漏污染溢出点的浓度随着时间增加，达到最大值后，浓度保持稳定。The survey results show that there are is above 890 m elevation, located to the east of dolomite aquifer of the goaf roof, separately disc two leakage systems of the the dump. The waste liquid harging and overflowing to dump. One is the goaf leakage which permeates into the goaf through the ＂800 adit＂ and ＂745 airway＂. The other system is the F10 - F6 fault leakage zone of the dump, and waste liquid permeates along dolomite aquifer of the faults area, running off and draining northward to the ＂S6 springs＂. Based on water quality monitoring da- ta, a one-dimensional analytical method and statistical method were utilized to calculate the hydrodynamic dis- persion parameters that show the fracture pore medium pollution mass migration has the characteristics of super- position concentration, the concentration of the leakage point pollution to increase over time, after reaching the maximum, concentration remained stable.
