| 摘 要： | 上隅角瓦斯积聚是采用综呆放顶煤技术开采高瓦斯易自燃煤层必须面对的难题。文章提出了利用工艺巷防止综放面上隅角瓦斯积聚的方法。并且，根据计算流体力学理论建立数学物理模型，模拟计算了综放工作面及采空区内空气、瓦斯流动的规律，有力地论证了该方法的可行性和有效性，为我国高瓦斯易自燃煤层综放工作面的瓦斯防治工作提供了新的思路。

| Abstract: | Gas accumulation in the upper corner is a difficult problem for a fully mechanized top-coal caving face in high gas-con- taining and easily spontaneous combustion seam.In this paper,a method is proposed to prevent gas accumulation in the upper comer by using process roadway.Based on the theory of computational fluid dynamics(CFD),a mathematical-physical model to simulate the flow of air and gas in fully mechanized top-coal caving face is built to prove the feasibility and effectiveness of the method.As a re... |
