灰色关联度分析法在煤与瓦斯突出模拟试验中的应用

Application of Grey Correction Analysis in Simulating Test of Coal and Gas Outburst

改进煤与瓦斯突出模拟试验装置,通过分别改变瓦斯压力、瓦斯含量、地应力、煤的含水率等条件,进行14次煤与瓦斯突出模拟试验。运用灰色系统理论的灰色关联度分析法,对模拟试验结果进行分析研究,得出煤与瓦斯突出强度的4个主要影响因素中,对突出强度影响最大的是瓦斯含量,其次是瓦斯压力,地应力,影响最小的为煤的含水率。

A set of device for simulating coal and gas outburst is Improved,14 times simulating tests are conducted under conditions of varied gas pressures,gas contents,ground stresses and coal′ s moisture contents.Afterwards,the simulating results are analyzed by grey correction analysis method in greysystem theory.Thus,it is obtained that among the four main factors that affect intensity of coal and gas outburst,gas content is the most influential and the next is gas pressure,then ground stress.While,coal′s moisture contents has the minimum influence.
