论文摘要：
       Abstract: In order to solve the problem of lower permeability of coal seam and improve the effective of under ground coal gasification, it has been studied on how low-carbon alcohol solution acts in coal, and on coal permeability in different low-carbon alcohol solutions like methanol, ethanol and isopropanol. The result shows that some organic substance has been extracted from coal under the effects of coal wetting, swelling, physical and chemical action when low-carbon alcohol solution acts on it, which leads to the changing of coal inner porosity, and an obvious change of coal permeability. It’s clear that the permeability after low-carbon alcohol solution acts in coal is higher than that of the original coal. The permeability increases obviously accompanied by the increasing of low-carbon alcohol solution’s volume and concentration. The changing rate of sample coal’s permeability is highest when isopropanol solution acts in coal while a lowest rate of methanol solution.
