摘　　要：针对已有可拓识别方法用于矿井突水水源判别时易造成误判的问题,提出了一种改进的可拓识别方法。首先对已有方法中经典域、节域量值范围以及待判物元的量值进行了归一化处理,并优化了最优值的选取,然后提出了新的位值计算方法。实验结果表明,将改进后的可拓识别方法应用到煤矿突水水源判别,提高了待判物元正确归属于某个含水层的程度,从而提高了水源判别的准确率。For high misjudgment rates of existing extension identification method which was applied in coal mine water bursting source discrimination,an improved extensicon identification method was put forward.The ranges of classical domain,joint domain and the value of evaluated matter-element of the existing method were normalized,and then the selection of optimal value was optimized.Finally,a new location value calculation method was proposed.Experiment results indicate that application of the improved method to coal mine water bursting source discrimination improves the level of matter-element belongs accurately to a certain aquifer,thus improves accuracy rate of water source discrimination.
