掘进工作面局部通风管理是煤矿通风安全管理的重要内容之一，尤其是对高瓦斯矿井而言，显得尤为重要和突出，如果系统不合理或管理不好，将会造成停电停风引起瓦斯积存，甚至发生瓦斯爆炸重大事故。本文以李子垭煤矿5102北机巷掘进工作面供风技术为例，从井下实际管理工作出发，对掘进工作面局部通风系统的安全可靠性进行了较为系统的研究分析，并提出了提高局部通风系统安全可靠性的方案措施和管理方法。从根本上防止瓦斯超限，为复杂地质构造、高瓦斯、软煤层中掘进工作面的可靠供风，提供了可以借鉴的经验，具有较高的推广价值。%The local ventilation management of the driving working face is one of the important parts of the safety management of mine ventilation, especially for highly gassy mine, it is particularly important and prominent. If the system is unreasonable or has bad management, it will cause the power and electric outage, the gas accumulation and even the gas explosion. This paper takes air supply technology of the driving working face of 5012 roadway in Liziya Coal Mine, from the actual management work in the mine to systematically study and analyze the safe reliability of the local ventilation system of the driving working face and put forward the solution measures and management methods to improve the safe reliability of local ventilation system of the driving working face. It fundamentally prevents the gas overrun and provides experience for the reliable air supply technology of the driving working face in the complex geological structure, high gas and soft coal seam. It has high promotion value.
