等容变压下不同煤的瓦斯放散规律研究
Study on Laws of Gas Diffusion Under Constant Volume and Pressure Swing
摘要
Abstract
By testing the gas diffusion velocity and volume of several coal samples using WT-1 constant volume and pressure swing device,eombined with the mathematical model of coal gas emission,the characteristics of gas emission were obtained.The experimental results showed that the △p index would fail to declare.By using the least squares method to fit the different mathematical formula for gas emission,the results show that Venter type is more suitable for formula of diffusion velocity within 1 min,and the greater the diffusion volume,the higher the relativity with Venter type.关键词
