摘要
在煤与瓦斯突出的综合作用假说的机理上,通过对煤的瓦斯放散初速度的影响因素进行全面的理论分析,运用量纲理论和方法分析各影响因素的量纲,建立煤的瓦斯放散初速度的数学模型,并对所得数学模型进行了比较分析和研究;最后在赵各庄煤矿采集和收集相关影响因素的资料,利用此模型计算出煤的瓦斯放散初速度并和实验室测定的煤的瓦斯放散初速度相比较,得到数值相差不大的结论。
On the mechanism of comprehensive effect hypothesis of coal and gas outburst, through comprehensive theoretical analysis of influencing factors of the coal gas diffusion initial speed, the dimensions of the various influencing factors are analyzed by using dimen- sional theories and methods. The mathematical model of coal gas diffusion initial speed is established, and the comparative analysis and research are done by using the mathematical model. Finally, acquring and collecting materials of related influencing factors in Zhao- gezhuang coal mine, comparing the coal gas diffusion initial speed obtained from mathematical model and laboratory testing, it is got the conclusion that there is little numerical difference.
