煤与瓦斯突出预报的模糊聚类相似分析法

影响煤与瓦斯突出的因素多数是定性的或是模糊相似，采用模糊聚类分析方法对煤炭与瓦斯突出程度进行分析，建立模糊模式；应用模糊相似选择原理进行评价，以模糊模式为评价对象，以待预报样本为参考对象，根据模糊模式与以待预报样本的相似程度进行预测预报。哪一模式与预报样本最相近，等待预报样本即属于那一突出类型。采用模糊聚类及模糊相似原理2种方法结合分析预测，不仅克服了模糊聚类单一分析方法的不确定性，使定性预报转为定量预报，而且提高了预报效果的准确程度。实例分析表明，这是预报煤与瓦斯突出危险程度的一种较好的方法。

Fuzzy gathering classification similar analysis for the coal and gas outburst

According to the feature that the factors influencing the coal and the gas outburst are qualitative or fuzzy similar,the author analysed the coal and gas outburst degree with the fuzzy gathering classification analytical method and set up fuzzy mode.Then using the fuzzy similar principle,taking the fuzzy mode as appraised object,the waiting to predict samples as reference objects,the author forecasted the coal and gas outburst.Which mode is most similar to predict sample,the predict sample is that outburst mode.The fuzzy gathering classification analytical method,combining fuzzy similar method can overcome the indeterminateness and change qualitative forecast to quantitative.The accuracy of forecast is improved.
