摘要
顶板瓦斯高抽巷的抽采效果与抽放负压直接相关。结合阳煤三矿K8206大采长综放面顶板瓦斯高抽巷实际抽采效果,通过数值模拟与现场实测数据分析,得出顶板瓦斯高抽巷抽采正常期最优抽放负压,以期对高瓦斯矿区顶板瓦斯高抽巷的合理抽放参数确定提供科学依据,实现矿井的煤与瓦斯安全高效共采。
The gas extraction effects is related to negative pressure of suction. Based on numerical simulation and field surveying datum analysis of K8206 in Yangquan Coalfield , it is found out the optimal negative pressure during normal time in high - level entry for gas extraction, providing scientific and reasonable technical parameters for high - level entry in gassy mines, so that the safe extraction of coal can be realized.
