摘要
应用灰色关联分析,对煤与瓦斯突出影响因素进行灰关联分析,得出了各影响因素对煤与瓦斯突出影响程度的大小排序;选择灰关联分析的5个优势因子作为输入参数,建立了煤与瓦斯突出预测的神经网络模型;用我国典型突出矿井的煤与瓦斯突出实例作为学习样本,对网络进行训练学习,并以云南恩洪煤矿的煤与瓦斯突出实例作为预测样本进行验证。结果证明该系统能较准确地预测煤矿的瓦斯突出情况。
This paper applied grey correlation analysis to analyze grey correlation about influence factors of coal and gas outburst, and got the order arrange of each influence factor according to the influence degree of coal and gas outburst. Choosing five advantage factors of grey correlation analysis as the input parameters, neural network forecasting model of coal and gas outburst was built. The network was trained by using the study samples from instances of typical coal and gas outburst mines in China, and coal and gas outburst instances of Yunnan Enhong mine were used as forecasting samples. Comparing the results from network forecasting with the results of the traditional methods, it proved that this method can meet the forecasting requirement of coal and gas outburst.
