摘　　要：针对采空区内埋管、瓦斯尾巷、高位瓦斯巷这三种采空区瓦斯治理方法,基于矿井通风理论、多孔介质渗流理论,建立了采空区流场计算模型,通过数值模拟,研究了三种瓦斯抽放方法的抽放效果以及对采空区流场的影响范围,并为瓦斯抽放过程中的采空区火灾防治提供有效的建议。In view of the gas control method of buried pipes in goaf, gas tail lane and high-order gas lane, and based on the theory of mine ventilation and porous media seepage theory, the goaf flow field calculation model is established. Through numerical simulation, the effect of the three methods of gas drainage and their influence on the goaf flow field are studied, and effective suggestions are put forward for the fire prevention and control in mined-out area in the process of gas drainage.
