摘 要本设计为双鸭山矿业东荣一矿矿井通风系统设计,东荣一矿共有 12 层可采煤层,本设计取其中条件较好的 12 和 16 煤层,煤层厚 m。设计井田的可采储量 t,效劳年限为年。矿井通风系统是组成矿井生产的一个重要环节。开发与生产相适应的合理的通风设计,可以更好的保证生产所需的充足、稳定的风量;且在较好的经济效果根底上,具备较强的抗灾能力,到达技术上的先进、合理、可靠本设计中采纳立井开拓方式。结合东荣一矿的地质条件、煤层赋存情况、以及整个矿井的瓦斯涌出情况,确定了东荣一矿的矿井通风系统,并计算出矿井的最大通风阻力,然后根据这些计算数据选出适宜的通风机。根据设计矿井的根本情况和通风系统,初步确定了瓦斯、火灾、顶板、热害等灾害的预防治理措施。关键词 :通风系统; 通风阻力; 通风机; 通风费用AbstractThis design is for the Dongrongyi Coal Mine of Shuangyashan Mining Limited Company about ventilation system, and Dongrongyi Coal Mine has 12 to be possible to mine coal the level, this design takes the condition good 12 and 16 coal bed, coal bed thickness ism, design well field's recoverable resources 120.75M ton , the service life is95.8 years.The mine ventilation system is an important part of the production. The ventilation design which is the reasonable combination of development and production could ensure adequate and stable air flow to produce better. Based on a better economic effect, it has the strong ability to resist disaster, and achieves advance, reasonableness and reliability on technique.This design mine pit selects the double vertical shaft development method. Unifies the Dongrong one ore the geological condition, the coal bed tax saves the situation, the mine pit production system as well as the entire mine pit gas discharge situation, had determined the Dongrong two ore's mine ventilation systems, calculate the mine pit initial period and the later period always need the amount of wind, ext...
