摘要
从系统论的角度出发，剖析了矿井涌水量预测方法中水文地质比拟法的理论意义，并根据系统分析方法讨论了矿井涌水量预计的比拟法模型的建立和优化原则．以裸露岩溶充水型煤矿为例，将矿区的月降水量、开采深度、巷道长度等因素作为系统的输入信息，矿井涌水量作为输出信息，使矿井充水条件分析转为系统辨识。用无约束最优化方法求解各输入信息对涌水量的影响。１２个月的实测值与计算值比较的结果表明，用系统分析法建立的涌水量预报比拟法模型具有令人满意的精度。
Theoretical significance of analogic hydrogeology is described from the viewpoint of system theory, which is one of the methods for prediction of mine water-make. The principles for establishing and optimizing a model was discussed on the basis of system analysis. Taking an exposed karst mine as an example, analysis of mine inundation conditions is converted into system identification, where factors as monthly precipitation, mining depth, length of roadway are regarded as input information and water-make is regarded as output information. Unconstrained optimization method is used to find out the effect of input information on water-make. A comparison between the measured data obtained in 12months and the calculated data showed that the model can achieve satisfactory accuracy.
