【摘要】 煤碳是我国的主要能源,在能源消费结构中占居主导地位,煤岩体是一种典型的孔隙裂隙结构体,在煤炭资源开发的过程中涉及到一系列渗流力学问题。探讨了煤层中瓦斯渗流特征及其规律,分析了煤与瓦斯的流固耦合作用,介绍了煤与瓦斯突出的失稳判据;分析了煤矿生产过程中对地下水的污染,对酸性矿井水的水岩作用问题作了初步探讨,同时对煤矸石的环境效应也作了分析;随着煤层开采深度的增加,矿井热害越来越受到学者的重视,分析了矿井热害的形成机理及其影响因素。最后提出了煤层开采中渗流问题的研究方向。更多还原

【Abstract】 Coal rock mass is a kind of typical pore and fracture structure,and a lot of seepage problems are involved in the development of coal.The seepage characteristics and law of the gas in coal seam are discussed,the fluid—solid coupling interaction of gas and coal are analyzed,and the criterion of coal and gas outbursts is presented.The seepage characteristics of the water-bearing bed above the coal seam and the water—rock coupling interaction in coal mining are analyzed.The pollution of groundwater in coal production and the water—rock interaction in acidic water mine are discussed.At the same time the environmental effect of coal gangue is analyzed.With the increase of mining depth,the mine heat harm is increasing,which is paid attention to by researchers more and more,and the forming mechanism and influencing factors of the coal mine heat harm are analyzed too.The trend in the study on the seepage problems in coal mining is predicted.更多还原
