逐差加权法在水源判别中的应用

The Application of the Differential Weighting Method in the Discrimination of the Water Bursting Sources

根据各含水层的水样化学资料,针对应用模糊综合评判方法解决水源判别常用的"超标加权法"和"偏标加权法"确定评判因素权重系数方面存在的不足,提出了更加适合于水源判别的权重系数确定方法——"逐差加权法",建立矿井突水水源判别模型,并通过与这两种方法对比,效果较好。

Based on hydro-chemical data of water sampes from each water-bearing stratum, and in the light of the shortages of the ＂super weighting method＂ and ＂biasing v eighting method＂ that are commonly used to determine the weighting coefficient of the judging factors for solving the ,liscrimination of the water bursting sources with the fuzzy comprehensive evaluation, this paper puts forward a method for determining the weighting coefficient, the differential weighting method, that is more suitable to make the discrimination of the water bursting sources, establishes the model for judging the water bursting sources in the mine, and obtains beter results comparing with the ＂super weighting method＂ and ＂biasing weighting method＂.
