葫芦素煤矿通风系统设计

我江斜牧大单14毕业设计说明书摘要本设计以葫芦素煤矿地质资料为基础进行了葫芦素煤矿通风系统设计，采用立井多水平开拓，综合机械化采煤方法。矿井有两个可采煤层，分别为21#和2-2#，由于两煤层间距过大，所以不进行联合开采，矿井的可采储量为147.4Mt,矿井年产量为1.8Mt,矿井的服务年限为59年。在困难时期和容易时期分别布置2个采煤工作面，2个备采工作面，4个掘进工作面。通过对比，掘进工作面选择了压入式通风方式，局部通风机型号为FBD6/2×18.5,整个矿井的通风方式是中央并列式。接着，按照矿井的通风系统平面图，绘制出困难时期和容易时期的通风网络图，根据通风网络图进行配风，并且进行风速校验，进而计算出矿井的最大通风阻力，然后选出主要通风机FBCDZ-8No28A,并计算所需的电费2.13元/吨，最后对可能出现的灾害进行预防和提出相应的措施。关键词：矿井通风：风量分配；风机选型；中央并列式我江钟牧大单毕业设计说明书ABSTRACTThis design is based on the geological data of Cucurusu coal mine ventilationsystem design,using shaft multi-level development,comprehensive mechanizedcoal mining method.The mine has two recoverable coal seams,namely 2-1#and 2-2#.Due to the large spacing between the two coal seams,joint mining is not carriedout.The recoverable reserves of the mine are 147.4Mt,the annual output of the mineis 1.8Mt,and the service life of the mine is 59 years.In the difficult period and theeasy period,two coal mining faces,two stoping faces and four driving faces arearranged respectively.By comparison,the driving face is selected as the pressingventilation mode,the local fan model is FBD6/2x18.5,and the ventilation mode ofthe whole mine is the central parallel type.Then,according to the ventilation systemplan of the mine,the ventilation network diagram of the difficult period and the easyperiod is drawn.According to the ventilation network diagram,the maximumventilation resistance of the mine is calculated,and the main fan FBCDZ-8-No28Ais selected,and the required electricity fee is 2.13 yuan/ton.Finally,the possibledisasters are prevented and the corresponding measures are put forward.Keywords:Mine ventilation;Air volume distribution;Fan selection;Centralparallel我江钟牧大单毕业设计说明书目录摘要ABSTRACT1矿区概况及地质条件1.1矿区概况1.1.1地理位置及交通1.1.2地质概况1.1.3煤质21.2矿井安全概况21.2.1井田水文地质情况21.2.2矿井瓦斯31.2.3煤层自燃倾向性和爆炸性32矿井储量与生产能力42.1井田境界及储量42.1.1井田境界2.1.2井田储量42.2矿井生产能力和服务年限53井田开拓73.1井田开拓方式73.2井筒及巷道布置3.2.1井筒形式及井口位置>3.2.2主要巷道布置83.3矿井带区接续153.3.1带区划分153.3.2带区开采顺序和接续计划16
