基于改进灰色关联分析方法的煤与瓦斯突出预测研究

Research on Coal and Gas Outburst Prediction Based on Improved Gray Associated Analysis

基于灰色系统理论,对灰色关联分析方法进行改进,包括分辨系数的改进以及采用距离分析法对比较序列进行赋权处理。利用改进的灰色关联分析模型,参考华北地区某矿历年来的突出资料,定量分析该矿4项煤与瓦斯突出的预测指标,确定最优预测指标。

Based on gray system theory, the gray associated analysis method is improved, including improved identification coefficient and endowing weight to comparative sequence by using distance analysis method. Referring the outburst information ＂of a mine in north, China over the years, quantitative analysis of four coal and gas outburst prediction index, determine the optimal predictors.
