七台河矿业集团新强煤矿万吨年矿井的通风设计 毕业设计.docx

 PAGE \* MERGEFORMAT XI 摘 要 本设计矿井为七台河矿业集团新强煤矿90万吨/年矿井的通风设计，矿井2层可采煤层24#、25#。设计井田的可采储量87.785Mt，服务年限为70a。采用斜井开拓，划分两个水平，九个采区。达产时采区为一采区，布置两个工作面，24#、25#层联合开采。采煤方法为走向长壁垮落采煤法，采煤工艺为综合机械化采煤工艺，顶板处理方法为全部垮落法。 矿井通风方式为分列式，通风方法为抽出式，采区通风系统为轨道上山和运输上山进风，回风上山回风，采煤工作面采用“U”型上行式通风，掘进工作面采用压入式通风，矿井容易时期设计需风量为59.15 m3/s，困难时期设计需风量为62.6m3/s。进而选出矿井主要通风机型号为FBCDZ-8-No22C，电动机型号为YBFe315M－8和YBFe355M1－8，且对矿井所需通风构筑物进行布置。 关键词：通风设计；矿井通风系统；通风阻力  ABSTRACT The design of mine for Qitaihe Xinqiang Coal Mining Group 900,000tons / year of new mine design, a total of 2 coal seam layer 24 #, 25 #. the design of mine recoverable reserves of 87.785Mt, length of service for the 70a double shaft design combined to open up the way,The mine uses the inclined shaft development, nine mining area. Mining area at the middle of a mining area , the layout of two face, 24 #, 25 # layers separate mining. Mining methods to falling down together wall coal mining law, mining technology for integrated mechanized top coal caving technology approach for the entire roof falling Act. Mine ventilation for parade type, the method of taking the type of ventilation, ventilation systems for the mining area and transport up the mountain track up the mountain into the wind, to wind up the mountain back to the wind, coal face using U-type upstream ventilation, the use of heading face pressure-in ventilation, mine design to be easy to time the wind was 56 m3 / s, designed to be a difficult time for the air flow 61m3 / s. Elected to the main mine fan model FBCDZ-8-No22C, the motor model YBFe315M－8 and YBFe355M1－8, and the structure of the mine ventilation required to set up their equipment. Key words ：ventilation design；mine ventilation system；ventilation resistance 目 录  TOC \o 1-3 \h \z \u  HYPERLINK \l _Toc326576867 摘 要  PAGEREF _Toc326576867 \h I  HYPERLINK \l _Toc326576868 ABSTRACT  PAGEREF _Toc326576868 \h II  HYPERLINK \l _Toc326576869 1 矿区及安全概况  PAGEREF _Toc326576869 \h 1  HYPERLINK \l _Toc326576870 1.1 矿区
