水-热耦合作用下的煤中瓦斯解吸规律试验研究
Experimental Study on Gas Desorption Laws in Coal by Hydro－thermal Coupling
摘要
Abstract
This paper takes the low permeability and difficult coal seam in Guizhou Province as the research object. Methane des-orption experiments were carried out at different temperature and moisture content with the HCA high-pressure capacity gas ad-sorption device. Research showed that the relationship between temperature and gas desorption amount in coal is positive, and the water content is negatively correlated with gas desorption amount in it, the temperature and water content have the most significant influence on gas desorption in coal during the first 30 minutes. Then the quantitative relationship between gas desorption amount in coal under water-heat coupling was deduced with the modified Barrell. Finally, the influence of four different coupling zones on gas desorption capacity in coal is theoretically analyzed.关键词
