防止瓦斯积聚的措施有哪些？

    所谓瓦斯积聚是指采掘工作面及其它地点，局部瓦斯浓度达到2%，体积超过0.5立方米。防止瓦斯积聚的措施有：
    （l）通风是防止瓦斯积聚的主要措施合理选择最佳的通风系统，加强通风管理，做到有效、稳定和连续不断，才能将涌出的瓦斯及时冲淡排出，使采掘工作面和生产井巷中的瓦斯浓度符合《规程》规定的要求。
    （2）及时处理局部积存的瓦斯生产中易于积存瓦斯的地点有：回采工作面上隅角，顶板冒落的空洞内，低风速的顶板附近，停风的盲巷，回采工作面采空区边界处及采煤机附近。及时处理局部积存的瓦斯，是矿井日常瓦斯管理的重要内容，也是预防瓦斯爆炸事故、保证安全生产的关键工作。通常采用的主要方法是：向瓦斯积存地点加大供风量或提高风速，将瓦斯冲淡排出；将盲巷和顶板空洞内积存的瓦斯封闭隔绝；必要时应采取抽放的措施。
