1、平煤一矿矿井通风设计平煤一矿矿井通风设计摘 要：本设计是根据中平能化集团平煤一矿的实际情况进行的局部矿井设计。井田内煤层赋存比较稳定，煤层倾角为 319，平均煤厚 1.93m，整体地质条件比较简单。根据井田资源条件，确定矿井年产量 60 万 t/a，服务年限约为 41 年。矿井确定采用立井单水平上下山开采，设计采用综合机械化采煤工艺，走向长壁采煤法，用全部跨落法处理采空区；矿井通风系统采用中央并列式，在工业广场内设中央风井，由副井进风，中央风井回风；矿井通风容易时期总阻力为2211.4 Pa，通风困难时期为 2697.2Pa，主要通风机选用 BDNO24 型通风机。设计以一个采区、一个综采面、
2、一个备采面、两个掘进头，保证矿井设计生产能力。本设计还包括矿井提升、运输、排水和矿井通风等系统的设备选型计算，以及矿井安全技术措施和环境保护方面的要求，使得整个矿井的初步设计更加完整。矿井全部实现机械化，采用先进技术和借鉴已实现高产高效现代化矿井的经验，实现一矿一面高产高效矿井从而达到良好的经济效益和社会效益。关键词：关键词：立井单水平 走向长壁采煤法 综采采煤工艺 中央并列式通风Zhongping of the Group Pingmei Coal Mine Ventilation DesignAbstract: The design is based on actual situation
