煤炭是我国工业可持续发展的重要保障。 矿井通风系统设计和网络优化的研究， 无论对 设计新矿井还是老井技术改造都会产生深远的影响，能为之带来重大的经济效益和社会效 益，而且能够对矿井通风学科的发展做出贡献。它是矿井安全生产的需要，是提高矿井抗灾 能力的需要，是确保矿井稳产、高产的需要杏彩平台通风设计_百度文库，是提高矿井经济效益的需要，是确保我国能源 安全的需要，是确保我国经济持续、快速、稳定发展的需要。
《煤矿安全规程》规定，每个矿井必须有完整的合理的通风系统。一个良好的矿井通风 系统是保证矿井安全高效生产的前提与基础。 矿井通风系统是向作业点供给新鲜空气， 排除 污浊空气的通风网络、杏彩官网登录 通风动力和通风控制设施等构成的工程体系， 它对安全生产状况有全 局性影响。 而通风系统是否合理， 与通风机装置的性能及与之匹配的井下网路系统有着密切 的关系。 要保证矿井通风系统处于良好的运行状态， 就必须使矿井主要通风机在最佳工况点 运行，就必须掌握全矿井井下通风网路中的各种通风基础技术参数。 本次设计的题目： 《某矿通风工程设计》 ，基于上述分析，此次设计将严格遵照规程所要 求的进行。
