摘　　要：为了研究丁集煤业深部煤层瓦斯赋存的真实状态,揭示丁集煤业深部煤层瓦斯赋存规律,基于多物理场耦合模型,通过数值模拟软件研究了淮南煤田丁集煤业深部煤层瓦斯赋存特点,研究得出瓦斯压力、瓦斯含量及煤层的渗透率随深度增加呈非线性分布,煤体变形量、煤体温度对原煤瓦斯含量、渗透率分布具有不同程度的影响。To study the real state of gas occurrence in deep coal seams of Dingji Coal Mine and to reveal the gas occurrence regularity of deep coal seams,the numerical simulation software was used to study gas occurrence characteristics of deep coal seams in Dingji Coal Mine of Huainan coalfield based on the multi physical field coupling model. The result showed that the gas pressure,the gas content and the coal seam permeability exhibited nonlinear distribution with the depth increasing,the deformation quantity of coal body and the temperature of coal had different influence on the gas content and the permeability distribution.
