摘要
通过分析煤层瓦斯产生的原因、赋存及运移规律,以及瓦斯应力对煤体物理力学特性的影响作用,研究煤层的透气系数、煤层厚度、抽放负压等因素对煤层瓦斯抽放效率的影响,对煤层瓦斯防突及抽放有重要的参考价值。
Through analyzing the gas form mechanism,existing state,travel rule,as well as the influence function of gas stress on the coal body physics mechanics,sevral important factors which have effects on gas drainage were studied,such as the gas permeability coefficient,coal layer thickness,drainage negative pressure.The study has important value to gas drainage and outburst prevention.
