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、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 of Pingmei coal mine, Zhongping Coal Industry Group in Henan. Coal seam is relatively stable within the mine, seam dip angle is 3 -19 , the average coal thickness is 1.93m, the overall geological conditions is relatively simple.According to the actual situation of geological data , the annual capacity is 0.6 million tons and the length of service is about 41 years. Decided to adopt the shaft of the mine down one level of exploitation, design integrated mechanized mining all high-mining techniques, toward the longwall mining methods, treatment with the entire cross-fall gob. Mine ventilation system is the central paratactic type, l central wind Well is located in Industrial square .The auxiliary shaft use into the wind, the wind well return air. Easy period total resistance of Mine ventilation is 2211.4 Pa and difficult ventilation period is 2697.2Pa, The main fan ventilation machine is the BDNO24type.Design with a panel, a compound mining, a mining face, and two tunneling, ensure that the design of mine production capacity. This design also includes mine elevator, transportation, water drainage and mine ventilation system s equipment selection , mine safety technical measures and environmental protection requirements, it aim to make the whole mine the preliminary design more complete. All mine mechanization, use of advanced technology and draw on modern high production and efficiency have been achieved experience of mine, a mine face to achieve high production and efficiency so as to achieve good economic and social benefits.Keywords:the shaft of the mine down one level of exploitation, toward the longwall mining methods , fully mechanized coal mining process ,the central paratactic type ventilation.目目 录录河南理工大学本科毕业设计河南理工大学本科毕业设计III1 绪 论.12 矿区概况及井田地质特征.22.1 矿区概况.22.1.1 地理位置与交通.22.1.2 地形地势及河流.32.1.3 气象/地震.32.2 地质特征.42.2.1 矿区范围内的地层情况.42.2.2 井田范围内和附近的主要地质构造.42.2.3 煤层赋存状况及可采煤层特征.62.2.4 煤质特征.82.2.5 井田内水文地质情况.92.2.6 开采煤层顶底板岩石工程地质特征.92.2.7 瓦斯、煤尘、煤层自燃倾向性、地温及地压.103 矿井井田境界、储量和服务年限.113.1 井田境界.113.2 井田储量.123.2.1 矿井工业储量.123.2.2 矿井设计储量.143.3 矿井年产量及服务年限.163.3.1 矿井工作制度.163.3.2 矿井设计生产能力.164 井田开拓及采区设计.174.1 矿井开拓方案的确定.174.1.1 井筒形式和数目.174.1.2 井硐位置及坐标.174.1.3 水平数目及高度.214.1.4 主要巷道布置情况
