平煤一矿通风系统专项的设计
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3°—19°,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,副井进风,中央风井回风通风容易时期 Pa, 通风困难时期Pa,主要通风机选用BDNO24型通风机。设计以个采区、一个综采面、保证矿井设计生产能力。中央并列式 Zhongping of the Group Pingmei Coal Mine Ventilation Design Abstract: 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,
