摘要
依据煤对瓦斯吸附的原理,通过对国内部分矿区进行现场采样,在实验室进行煤的残存瓦斯含量测定,并分析了其与煤样粒度及挥发分的关系,为矿井瓦斯涌出量预测及煤层残余瓦斯含量的确定提供技术支持。
Based on the principle of coal gas adsorption,through site sampling in the domestic part mining area,the determination of the residual gas content of coal is carried out in the laboratory,the relationship between coal granularity,volatile and coal residual gas content is analyzed,which provides technique support for the prediction of mine gas emission and the determination of coal seam residual gas quantity.
