防止矿井空气污染的措施有哪些？ | 2011-8-5 10:28:00

防止矿井空气污染的措施有哪些？

    煤矿中各种有害气体，通常都在通风不良的旧巷、采空区和火区附近以及在炮烟、沼气和煤尘爆炸时的风流中。为保证井下空气的清洁程度，防止矿井空气污染，主要采取以下措施：
    （1）稀释、排除污染物，即用新鲜风流将有害气体和矿尘稀释到安全浓度以下，并把它排出矿井。
    （2）封闭火区、采空区、旧巷和不通风的巷道，减少有害气体的生成，并可防止有害气体扩散到矿井空气中，同时也可防止人员窒息和矿井火灾、沼气爆炸等。
    （3）加强对有害气体的检查，掌握涌出情况，定期对工作面、采空区进回风巷采取空气试样，送到化验室分析空气成分，了解空气的清洁程度。
    （4）减少有害气体生成和净化风流，禁止使用不合标准的炸药，放炮时使用水炮泥和喷雾洒水；净化风流；加强火区管理，防止火灾、瓦斯和煤尘爆炸。
