煤矿进行安全生产的关键因素就是建立和完善矿井通风系统。评价通风系统的安全状况可为煤矿的安全生产提供技术支持。安全评价技术的不断改进和创新对煤矿安全生产的发展至关重要。因此，准确地掌握矿井瓦斯分布和运移规律，预测矿井瓦斯涌出量，确定合理有效的瓦斯抽采井位是一个难点。基于此，本文简要讨论了矿井通风和瓦斯抽采技术的研究和应用。“,”The key factor for safe production in coal mines is to establish and improve the mine ventilation system. Evaluating the safety status of the ventilation system can provide technical support for the safe production of coal mines. The continuous improvement and innovation of safety evaluation technology is very important to the development of coal mine safety production. Therefore, it is difficult to accurately grasp the gas distribution and migration laws in the mine, predict the gas emission in the mine, and determine the reasonable and effective gas drainage well location. Based on this, this article briefly discusses the research and application of mine ventilation and gas drainage technology.
