煤层突出倾向与其孔隙结构的相关性研究

Coal Outburst Tendency and Correlation Study on Pore Structure

以沁水煤田余吾煤矿为例,通过实验室实验的方法分析煤样的微观孔隙结构、孔容和孔比表面积在一定孔径范围内的分布规律,并结合矿井瓦斯的赋存、吸附和解吸释放机理来分析预测矿井的瓦斯突出危险性。

Taking Yuwu Colliery, Qinshui Coalfield for example, the author analyzes the microscopic pore struc- ture, pore volume of coal sample and the distribution law of pore specific surface area within certain pore size by laboratory experiments, and makes a prediction of gas outburst risk according to gas occurrence, adsorption and desorption release mechanism in mines.
