摘要
为分析水分对瓦斯解吸规律的定量影响,采用模拟测试和理论分析相结合的方法,在不同吸附平衡压力、不同水分含量条件下对新景矿3号煤层瓦斯解吸规律进行了模拟测定,通过对试验数据的拟合分析,得出水分对瓦斯解吸规律的影响系数,并对取得的水分影响系数进行了验证和对比。试验结果表明:影响系数经过校正后的解吸曲线和试验得出的解吸曲线几乎重合,这说明该影响系数能很好地描述不同水分含量下的瓦斯解吸规律,最后对水分对瓦斯解吸规律的影响进行了理论分析。
In order to analyze the quantitative influence of the moisture to the gas desorption law,the method combined with the simulation measurement and test and the theoretical analysis was applied to the simulation measurement of the gas desorption law for No.3 seam in Xinjing Mine under the conditions of the different adsorption balanced pressure and the different moisture content.With the fitting analysis on the experiment data,the influence coefficient of the moisture to the gas desorption law was obtained and the verification and comparison of the moisture influence coefficient obtained was conducted.The experiment results showed that with the correction of the influence coefficient,the desorption curve and the desorption curve obtained from the experiment could be almost fit.Thus the influence coefficient could well describe the gas desorption law under the different moisture content.Finally the paper had a theoretical analysis on the moisture affected to the gas desorption law.
