【摘要】 煤层瓦斯渗流是煤与瓦斯突出研究中的一个重要方面,由于煤层处于复杂的地质环境中,煤层瓦斯渗流必然受到地球物理场的影响.本文基于国内外煤层瓦斯渗流研究现状,综合论述了地应力场、地温场、地电场对煤层瓦斯渗流的影响,以及多场耦合作用下的煤层瓦斯渗流,并从实验研究、理论分析、工程实践论证相结合的角度,展望了该研究领域中需要深入研究的方向和有关的发展趋势.更多还原

【Abstract】 Gas seepage in coal-bed is an important aspect of studies on coal and gas outburst.Due to the complex geological environment,inevitably coal seam gas seepage is affected by the geophysical field.Based on the current status of studies on coal seam gas seepage at home and abroad,this paper summarizes the seepage property of coal seam gas affected by the in-situ stress field,geothermal temperature field and geo-electric field as well as coupled flows.Finally it has put forward the further research direction and the development tendency of this field from the view that the experimental study,the theoretical analysis and the project practice proof should be unified.更多还原
