1、I摘 要本设计为新久煤矿二井 0.9Mt/a 通风设计，共有可采煤层 2 层，分别为6、10 煤层，煤层厚度均为 2.65m。设计井田的可采储量 64.54Mt，设计服务年限为 52a，煤层平均倾角为 5，采用的采煤方法为倾斜长壁采煤法，采煤工艺为综合机械化采煤工艺，掘进工作面采用压入式通风，选用 FBD-NO.6.0/37 局部通风机和直径 1000mm 的帆布风筒，顶板处理方法为全部跨落法。矿井通风方式为中央并列式，通风方法采用抽出式，带区通风设计中，回采工作面通风方式为 U 型。本设计还对矿井通风阻力容易时期和困难时期的需风量进行了计算与分配。经计算：矿井容易时期为东一带区投产，总需风量
2、为 97.96m /s，矿井通3风总阻力为 555.181Pa，矿井等积孔为 4.95m2；矿井困难时期为西二带区投产，总需风量为 102.05m /s，矿井通风总阻力为 1837.429Pa，矿井等积孔为32.83m2。同时设置通风设施，并制定灾害防治措施。最后选择主要通风机，型号为轴流式 FBCDZ-8-No28A；电动机型号为 YBFe355M2-8。关键词：通风方式；通风系统；风量分配；灾害防治IIABSTRACTThis design for the xinjiu coal mine two well 0.9Mt/a new mine design, with a total of
3、minable seam layer 2, 6 and 10 coal seam, the total thickness of coal seam is 5.3m. Design field recoverable reserves of 64.54Mt, length of service for 52a, the average Angle of coal seam as 5, the coal mining method for inclined longwall mining method, mining technique for comprehensive mechanized
4、coal mining technology, adopt tunneling faces pressure ventilation, selects the FBD-NO.6.0/37 partial ventilator and the canvas with a diameter of 1000mm ram, treatment method for all across the fall of roof. Mine belongs to the gas of the mine, ventilation mode for the side-by-side, ventilation met
5、hods draw-out, zone ventilation design, the working face ventilation way for U, upward ventilation.The design of mine ventilation resistance also easy and difficult period of air volume was calculated and the distribution. By computing: easy for east region area during the period of mine production,
6、 air volume of 97.96m /s, total resistance of 3mine ventilation is 555.181Pa, mine product such as hole of 4.95m2; Mine hard times for west two belt region and put into production,Total air volume of 102.05m/s, total resistance of mine ventilation is 1837.429Pa, mine product such as hole is 32.83m2.
7、At the same time set the ventilation facilities and formulate disaster prevention and control measures. Finally choose main ventilator, models for axial FBCDZ-8- No28A; Motor model for YBFe355M2-8.Key words: ventilation mode; Ventilation system; Air distribution; Disaster prevention and controlIII目
