基于 AHP-GRA 模型的煤与瓦斯突出危险性预测

摘要

According to the basic principle of AHP-GRA ( analytic hierarchy process-grey relational analy-sis) model, analyze the influence of index of system ’s outburst danger, and using correlation analysis to streamline tertiary indicators in order to reduce the sample size .By adding weight and optimize the Gray model, to improving the convergence speed , While increasing the accuracy of prediction model .Through regional analysis , combined with the instance , validate that the model can effectively predict the outburst dangerous level of coal mine system .%根据AHP-GRA模型的基本原理，分析系统突出危险性的影响指标，为降低样本量采用相关分析精简三级指标。通过加入权重，优化灰色关联模型，在提高收敛速度的同时，增加模型预测的准确性。通过区域性分析，并结合实例验证了该模型能有效预测煤矿系统的突出危险性等级。
