摘　　要：根据已知水源、出水点典型化学离子组分含量等数据,采用运筹学方法,建立矿井出水点多水源判别数学模型,并利用简约梯度法对模型进行求解。在模型求解过程中引入的松弛变量具有重要的物理意义,如果解中松弛变量取值较大,则意味着存在未知水源。采用文献及矿山实际数据进行验证,结果表明,该方法不仅适用于多水源出水的情况,判别已知水源是否与出水点导通,计算各水源在出水中所占的比例,而且还能揭示是否存在未知水源。According to the data of known water sources and water exit＇s typical chemical ions＇constituent content,etc,used the operations research method,the mathematical model was built to discriminate the mine effluent points＇ multi-water sources,in which utilized the general reduced gradient （GRG ） method to solve the model. In the process of solving it,the slack variable was introduced,which had an important physical meaning. If the slack variable of the solution has a larger value,it means there＇s an unknown water source. The model was verified by taking advantage of the documents and actual mining information,and the result shows this method can not only be used suitably in the multi-water sources＇effluent cases to discriminate whether the known water-sources is conducted with the water-exit and to calculate each water source＇s proportion in the effluent waters,but also can be used to reveal the existence of an unknown water source.
