盛和一矿矿井通风设计

工我江钟技大单毕业设计说明书摘要矿井地下有一层可采煤层，储量达31.8Mt,设计年产能为0.6Mt,服务年限为40.8a。矿井开采采用斜井方式，针对一采区单水平展开开采。通风系统采用中央分列式，三条上山通道被设计以服务于轨道运输、回风和物资运输的不同需求。其中，一个采煤面和两个掘进面被纳入设计之中。采煤面通过U型上行抽出式通风来优化空气质量，而掘进面则利用FBDNO.6.0/30型号的局部通风机实施压入式局部通风。需风量的详细计算与分配已针对通风阻力的不同阶段一一容易和困难时期完成。在容易时期的最大通风阻力数值是952.2P。即便在困难时期，最大通风阻力为1266.3Pae关键词：矿井通风；通风设计；通风阻力。我江斜技大单毕业设计说明书ABSTRACTThere is a exploitable coal seam underground in the mine,with a reserve of31.8Mt,a designed annual production capacity of 0.6Mt,and a service life of 40.8years.The mining adopts a inclined shaft method and is carried out horizontally in thefirst mining area.The ventilation system adopts a central parallel type,and three uphillpassages are designed to serve the different needs of rail transportation,return air,andmaterial transportation.One coal mining face and two excavation faces were includedin the design.The coal mining face optimizes air quality through U-shaped upwardextraction ventilation,while the excavation face uses FBD NO.6.0/30 localventilation fan to implement pressure type local ventilation.The detailed calculationand allocation of required air volume have been completed for different stages ofventilation resistance -easy and difficult periods.During the easy period,corresponding to a maximum ventilation resistance value of 952.2Pa.during the hardperiod,the maximum ventilation resistance of 1266.3 PaKey.words:mine ventilation;Ventilation design;Ventilation resistance我江斜技大单毕业设计说明书目录摘04ABSTRACT.1矿区及安全概况井田地质特征1.1矿区概况1.1.1交通位置11.1.2地形地势21.1.3水量的分布及范围21.1.4气象21.2井田地质特征21.2.1地质21.2.2主要地质构造41.2.3煤层赋存状况及可采煤层特征1.2.4岩石性质、厚度特征41.2.5煤质、牌号及用途52矿井储量与生产能力2.1井田境界及储量62.1.1井田境界确定依据..…2.1.2井田未来发展情况62.1.3井田储量2.2矿井工作制度生产能力和服务年限72.2.1矿井工作制度.72.2.2矿井生产能力的确定82.2.3服务年限83井田开拓.103.1井田开拓方式103.2井田开拓10白11I
