1、摘 要本设计矿井为双鸭山矿业集团有限责任公司东荣一矿0.9Mt/a新井设计，共有14层可采煤层，本设计取其中条件较好的24#和26#煤层，煤层厚度为5.2m。设计井田的可采储量120.75M万t，服务年限为95.8年。本设计矿井采纳立井开拓方式。结合东荣一矿的地质条件，煤层赋存状况，矿井生产系统以及整个矿井的瓦斯涌出状况，确定了东荣一矿的矿井通风系统，通过计算求出矿井的最大通风阻力，再依据这些参数选出合适的主要通风机。依据设计矿井的基本状况和通风系统，初步提出了瓦斯、火灾、顶板、热害等灾难的防治措施。关键词 ：通风系统 通风阻力 通风机AbstractThis design mine pit
2、for the Shuangyashan mining industry group Limited liability company Dongrong one coal mine 0.9Mt/a new well design, altogether has 14 to be possible to mine coal the level, this design takes the condition good 24# and 26# coal bed, coal bed thickness is5.2m, design well fields recoverable resources
3、 120.75M ten , the service life is95.8 years. This design mine pit selects the double vertical shaft development method. Unifies the Dongrong one ore the geological condition, the coal bed tax saves the situation, the mine pit production system as well as the entire mine pit gas discharge situation,
4、 had determined the Dongrong two ores mine ventilation systems, calculate the mine pit initial period and the later period always need the amount of wind, extracts the mine pit through network resolving the most greatly flowing resistance, acts according to these parameters to select the appropriate
5、 main ventilator again.Based on the fundamental state and ventilation system of the designed coal mine, the preliminary prevention and control measures of some disasters, suchas gas, fire and roof disaster, are presented in this design.Key word：Development ventage；Entirely windage；Resistance ventila
