摘　　要：瓦斯含量是确定煤层煤与瓦斯突出危险性的重要指标之一,研究煤样的瓦斯解吸规律对于煤层瓦斯含量测试的准确性以及反映煤体的突出危险性至关重要。以寺河矿东井区四盘区3#煤层煤样为研究对象,建立了煤样瓦斯解吸的实验系统,分析了煤样在不同温度和瓦斯压力下的解吸规律,以便为指导类似矿区采用瓦斯含量预测煤与瓦斯突出提供理论支撑。Gas content is an important indicators to determine the risk of coal and gas outburst,the gas desorption laws of the coal is crucial for the accuracy of gas content measurement and the reflecting of the coal and gas outburst danger. The gas desorption experiment system was developed for 3# coal samples from the No. 4 Panel of the eastern shaft area in Sihe Coal Mine. Under the conditions of different temperature and gas pressure,the desorption rules of the two types of coal samples were analyzed. The experimental results are gained for providing the prominent theoretical support to guide the gas content prediction method of coal and gas outburst for the similar mining area.
