双鸭山市三合顺煤矿矿井通风系统设计

我江钟技大单毕业设计说明书摘要矿井通风设计是矿山安全生产的一项关键性工作，合理的井下通风为作业提供安全保障的同时，在节约资源与成本方面也能带来可观的收益。本设计矿井以双鸭山市三合顺煤矿模型为基准的矿井通风设计。本设计井田开采煤层为一号煤层，矿井可采储量约为84Mt,年产量为0.9M,服务年限为67年，根据三合顺煤矿的实际情况选择上山的开拓方式，并进行水平划分和巷道布置，根据各采区服务年限进行采区接续。本设计确定了采区通风方法选定了局部通风机型号FBD5.6/2x11,并绘制了三合顺煤矿的平剖面图。本设计矿井依据绝对瓦斯涌出量、巷道断面面积、工作面长度与其相对应的参数等数据，计算三合顺煤矿通风难易时期各用风地点风量并进行风速校验。本设计矿井绘制出难易时期通风网络图，计算矿井总风阻与等积孔；计算主要通风机工作风量与风压，确定主要通风机型号；概算矿井通风电费，分析危险源并确定应对措施，以达到维持设计采区安全生产的最终目的。关键词：矿井通风：通风系统设计：风量分配：安全生产我江斜牧大单毕业设计说明书ABSTRACTMine ventilation design is a key task of mine safety production,reasonableunderground ventilation to provide safety for the operation,but also bringconsiderable benefits in terms of resource and cost saving.The design of mine ventilation is based on the model of Sanheshun coal minein Shuangyashan City.The mine mining coal seam in this design is No.I coal seam,the recoverable reserves of the mine are about 84Mt,the annual output is 0.9Mt,andthe service life is 67 years.In this design,the local ventilator model FBD5.6/2X 11was selected for the mining area ventilation method,and a flat profile of theSanheshun coal mine was drawn.According to the absolute gas outflow,roadway section area,working facelength and corresponding parameters of the design mine,the air volume of eachwind consumption site during the ventilation period of Sanheshun coal mine isdifficult and the wind speed is calibrated.In this design mine,the ventilationnetwork diagram in the difficult period is drawn,and the total wind resistance andequal product hole of the mine are calculated.Calculate the working air volume andwind pressure of the main fan,and determine the main fan model;Estimate mineventilation and electricity costs,analyze hazard sources and determinecountermeasures,so as to achieve the ultimate goal of maintaining safe productionin the design mining area.Key words:mine ventilation;ventilation system design;air volumedistribution;SafetyⅡ我江斜技大单毕业设计说明书目录摘要ABSTRACT目录ⅢCONTENTSVI1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1.1.2地形地貌21.1.3电源条件21.1.4地震21.2井田地质特征21.2.1地质构造21.2.2煤层赋存状况及可采煤层31.2.3煤岩性质31.3矿井安全概况41.3.1矿区水文地质情况41.3.2矿井瓦斯41.3.3煤层自燃倾向性42矿井储量与生产能力52.1井田境界及储量52.1.1井田境界.52.1.2井田储量.52.2矿井的生产能力和服务年限63井田开拓73.1井田开拓7Ⅲ
