摘　　要：地下水流速从传统计算方法是从二阶不稳定渗流方程出发,求出地下水头分布,然后按照达西定律用差分法或有限元法求出渗流速度,相对误差为20%～30%。在介绍自然电位法和孔间示踪法现场测定地下水流速和流向测量原理的基础上,用实例说明了埋深800m以下煤系含水层地下水流速和流向的测定和计算方法。结果表明,运用自然电位法和孔间示踪法所测的流速的误差为6.97%,与传统方法有很大提高,其结果可为煤矿建井提供比较准确的水文地质参数。The traditional computing procedure of groundwater flow rate is starting from second order unsteady seepage equation, then using difference method or finite element method find out seepage velocity in accordance with Darcy＇s law, the relative error is within 20-30%. Based on introduction to the principles of groundwater flow rate and current direction site determination using spontaneous potential method and interborehole tracer method, have demonstrated coal measures aquifer groundwater flow rate and current direction determination and computing methods through living examples. The results have demonstrated that the error of flow rate through spontaneous potential method and interborehole tracer method is 6.97%, compared to the traditional method has improved obviously, thus the results can provide rather correct hydrogeological parameters for coalmine construction.
