煤与瓦斯突出影响因素综合评价研究——基于改进熵权法+灰色系统关联法的研究

Comprehensive Evaluation of Influence Factors of Coal and Gas Outburst——Based on the Improved Entropy Weight Method+Grey System Correlation Method

提高煤与瓦斯突出危险性评价的准确性,加强煤与瓦斯突出防治和安全监管监察工作,对煤矿企业安全管理具有重要意义。文章通过构建瓦斯突出评价指标体系,利用改进熵权灰色关联法分析计算影响煤与瓦斯突出各指标关联度,结果表明:改进熵权灰色关联分析法能够有效评价各影响因素对煤与瓦斯突出危险性的影响,对应影响煤与瓦斯突出危险性因素排序依次为煤层倾角、煤层开采深度、煤层瓦斯含量、煤层瓦斯压力、瓦斯放散初速度和煤的坚固性系数,为煤矿企业有效预防煤与瓦斯突出、提高瓦斯突出应急管理提供了借鉴。

It is of great significance to improve the accuracy of coal and gas outburst risk evaluation,strengthen the prevention and control of coal and gas outburst and safety supervision and supervision.In this paper,by constructing evaluation index system of gas outburst,improved grey relation entropy method is used to calculate impact each index correlation of coal and gas outburst,the results show that the improved grey relation entropy analysis,can effectively evaluate the influencing factors of influence on coal and gas outburst risk,corresponding to the impact of coal and gas outburst dangerous sort of dip Angle of coal seam,the mining depth of coal seam,coal seam gas content,coal seam gas pressure,gas radiation initial velocity and the consistence coefficient of coal,for coal and gas outburst in coal mining enterprises to effectively prevent and improve the gas outburst emergency management provides the reference.
