论文以淮南矿业集团丁集煤矿突出煤层为试验点,采用压汞试验法对煤层孔隙进行研究,得出孔隙半径不同时,瓦斯赋存状态不同,游离和吸附的瓦斯含量也不同。在此基础上,利用高压容量法对煤样进行吸附试验,并结合工业分析结果,分析煤层瓦斯吸附量,根据丁集煤矿实际情况,考虑温度因素对瓦斯吸附试验的影响,为煤与瓦斯防突预测提供依据。
In this paper, taking the outburst coal seam of Dingji coal mine of Huainan Mining Group as the test point, the pore of coal seam is studied by mercury intrusion test. It is found that when the pore radius is different, the occurrence of gas is different and the content of free and adsorbed gas is also different. On this basis, the high pressure capacity method was used to conduct the adsorption test of coal samples. Combined with the industrial analysis results, the gas adsorption capacity of coal seam was analyzed. According to the actual conditions of Dingji coal mine, the influence of temperature on gas adsorption test was considered. Projection to provide the basis.
