摘 要: 从系统工程学理论角度出发,通过对采掘-排水-地下水系统致灾机制进行分析,确定了大水矿山地下水水害致灾主要是由系统中关键参量特性决定的,即由相邻水文地质单元径流补给、大气降水补给及排水系统排水量的不确定性导致;通过对3个主要影响因素的随机特征分布进行研究,得出系统灾害发生概率计算方法,为预测系统的灾害概率提供依据;将失效模型与矿山地下水模型结合,得到了地下水灾害强度及分布特征。该研究量化了矿山灾害,为制定水害防治方案提供一定的科学依据。

Abstract:From the perspective of systematic engineering, the disaster mechanism of excavation-drainage-groundwater system was analyzed, which is determined by the critical parameters of the system, including the runoff supply of adjacent hydrogeological units, atmospheric precipitation recharge and the water discharge uncertainty of the drainage system. The method of calculating the probability was derived when the systematic disaster occurs by analyzing the random distribution characteristics of three main influencing factors, which can afford reference to predict the hazard probability. Then the distribution characteristics of disaster intensity of groundwater were obtained by combining the failure mode with the mining groundwater model. In this study, the mine hazard was quantified, and it would provide scientific basis for prevention and control of water disaster.
