国内影响瓦斯渗流因素的研究现状及发展趋势

Research Status and Development Trend of Factors Influencing Gas Seepage of China

针对目前国内对影响瓦斯渗流因素研究较为不成熟、无体系、研究少的问题,对影响煤体中瓦斯渗流的因素进行综述及分析。重点评述了煤体结构、温度、电场、水分、煤的吸附作用、瓦斯压力、煤体应力等7个因素对瓦斯渗流过程的影响。结合煤炭行业发展趋势及相关理论分析,提出未来影响瓦斯渗流因素的研究热点。

In view of the current domestic research on the influence of gas seepage factors,summarized and analyzed the research on the factors affecting gas seepage in coal. Reviewed effects of seven factors,such as coal structure,temperature,electric field, moisture,coal adsorption,gas pressure and coal stress,on gas seepage process. Combined with the development trend of the coal industry and related theoretical analysis,proposedresearch hotspots affecting the gas seepage factors in the future.
