负压环境下煤的瓦斯解吸规律试验研究
Study on the law of gas desorption under negative pressure
摘要
Abstract
In order to study the gas desorption law under negative pressure,the laboratory simulation test of gas desorption process regarding the coal sample from Yangquan Sijiazhuang coal mine under negative pressure was implemented,accordingly,the measured data of the gas desorption varied with time was achieved with the coal sample was at different adsorption pressures and desorption negative pressures.The effect of different desorption negative pressures on the gas desorption of the coal sample at certain adsorption equilibrium pressure is analyzed.Applying the common empirical equations to process the regression and error analysis for the measured data,using Wang you-an equation as model,a new empirical equation for the coal gas desorption was established with the negative pressure,and the result shows the new established empirical equation can describe the gas desorption law of the coal under negative pressure.关键词
