高抽巷负压对采空区瓦斯涌出和自然发火的影响

为了使瓦斯高抽巷达到最佳的抽采效果,通过数值模拟,得出郑煤集团某矿顶板瓦斯高抽巷正常抽采期间的最优抽放负压,以期为具有自然发火的高瓦斯矿区顶板瓦斯高抽巷抽放参数的合理确定提供科学依据,从而实现矿井瓦斯防治和防灭火工作的协调统一。

Influence of Negative Pressure on Gas Emission and Spontaneous Combustion in High-level Gas Drainage Roadway in Goaf

To make the high-level gas drainage roadway achieve the best effect,based on numerical simulation,the best negative pressure was proposed on roof high-level gas drainage roadway in normal gas drainage period in a coal mine of Zhengzhou Coal Group Industry Co.,Ltd.,which is wished to provide scientific evidences for finding the reasonable gas drainage parameter,and to reach the coordination and unity of gas control work and fire prevention work.
