摘要
针对采空区瓦斯涌出源位置为上邻近层和底板遗煤均匀涌出、下邻近层和底板遗煤均匀涌出2种情况下采空区流场及瓦斯运移进行数值模拟,得到采空区瓦斯涌出源位置不同时,采空区及上隅角瓦斯浓度和高位巷抽采瓦斯纯量。
Simulates the airflow field and gas transport in goal under the location of gas emission in goal is the top adjacent strata and the fallen coal near floor, the lower adjacent strata and the fallen coal near floor. The gas distribution in goaf and upper corner, the gas quantity drained out by high-position tunnel are analyzed under the different the location of gas emission.
