摘要
为研究掌握祁南煤矿72煤层的瓦斯赋存规律及煤层瓦斯灾害程度,文章首先分析论述了煤层瓦斯基本参数的物理意义及测试方法,通过现场打钻测定及实验室取样测试分析等工作,得出了煤层瓦斯压力、含量随深度的变化规律,结合其他煤层指标,获得了72煤层的煤层瓦斯赋存规律,并对煤层进行了区域划分,为下一步的煤层瓦斯治理提供了理论基础。
In order to reveal gas occurrence law and gas disaster of 72 seam in Qinan coal mine, we firstly analyzed physical meaning and test method of basic parameters of gas in coal seam. By carrying out research, such as drilling the boreholes on site and testing coal sample in the laboratory, the variation of gas pressure and gas content with the depth had been achieved. And then, combining with oth- er coal index, we had obtained gas occurrence law of 72 coal seam. In addition, the region was divided in coal seam, providing theoret- ical basis to control gas in the future.
