摘　　要：对采空区氧气浓度场分布规律的数值模拟技术进行研究,介绍采空区氧气浓度场数值模拟的理论基础,阐述应用FLUENT开发采空区氧气浓度场CFD模型的方法与步骤,给出了模型中主要参数的确定方法。最终应用数值模型对东滩煤矿143下09工作面采空区的氧气浓度场分布规律进行模拟,模拟结果与实测数据基本吻合,结果表明,基于FLUENT的数值模拟技术是研究采空区氧气浓度场的分布规律的可靠手段之一。The paper had a study on the numerical simulation technology for the oxygen concentration field distribution law in the goaf. The paper introduced the theoretical basis of the numerical simulation for the oxygen concentration field in the goal. The paper stated the method and steps of the FLUENT to develop the CFD model of the oxygen concentration field in the goal. The paper provided the method to set the main parameters of the model. In the end, the numerical model was applied to the simulation on the oxygen concentration field distribution law of the goal in the No. 143Down09 coal mining face of Dongtan Mine. The simulation results ware basically fit with the site measured data. The results showed that the numerical simulation technology based on the FLUENT would be one of the reliable means to the study of the distribution law of the oxygen field in the goaf.
