摘要
本文运用渗流力学和扩散动力学理论,对注氮在采空区内运动、扩散特征和影响因素进行分析,提出了氮气在采空区运移和分布的数值模拟方法,并进行了计算和分析.
Applying infiltration theory and diffusion dynamics, this paper analyzes movement and diffusion feature of nitrogen injected in goaf and puts forward a method of numerical stimulation. In the end, an example of calculation and analysis is given in this paper.
