【摘要】：针对含瓦斯煤渗流模型的研究,是科学制订矿井瓦斯抽采作业规划或煤层气开发部署方案的理论依据。对含瓦斯煤渗流模型的研究成果进行了系统的梳理,并就相关理论的适用性进行了详细的分析。结合当前我国煤炭行业的发展趋势,指出了含瓦斯煤渗流模型研究的发展方向:(1)考虑"吸附解吸迟滞现象"的瓦斯扩散模型研究;(2)煤自身孔隙、裂隙结构与非线性渗流模型中各关键参数之间关联的微观作用机制研究;(3)基于非线性渗流—扩散与多物理场耦合作用影响的含瓦斯煤渗流模型研究。
[Abstract]:The research on seepage model of gas-bearing coal is the theoretical basis for drawing up the plan of mine gas drainage operation or the development and deployment of coalbed methane. The research results of gas-bearing coal percolation model are systematically combed, and the applicability of relevant theories is analyzed in detail. According to the development trend of China's coal industry, this paper points out the development direction of the research on gas-bearing coal percolation model: (1) gas diffusion model considering "adsorption and desorption hysteresis"; (2) coal porosity; The microscopic mechanism of the correlation between the fracture structure and the key parameters in the nonlinear seepage model is studied. (3) the study of the gas-bearing coal seepage model based on the coupling effect of nonlinear seepage and diffusion and multi-physical field.
