矿井通风系统优化及主扇改造技术研究

Study on Mine Ventilation System Optimization and Main Fan Transformation Technology

煤矿采区位于村庄下方,考虑村庄搬迁的难度,尚没有具体的工作面开采计划,但结合矿方实际生产任务,西风井担负区域(五采区和二采区)存在同时开采情况。通过研究应对原主扇与通风困难时期通风系统匹配性进行分析,论证原主扇能否满足困难时期的用风需求。为保证西风井担负区域生产任务要求,需对现况下通风系统进行优化改造,达到节能降耗的效果并为西风井主扇改造提供科学依据。

The coal mining area is located below the village.Considering the difficulty of village relocation,there is no specific mining plan for the working face.However,combined with the actual production task of the miner,there are simultaneous mining conditions in the west air shaft area(the fifth mining area and the second mining area).Through this study,the matching between the original main fan and the ventilation system in the difficult period should be analyzed to demonstrate whether the original main fan can meet the demand for air in the difficult period.In order to en-sure that the west air shaft can meet the requirements of regional production tasks,it is necessary to optimize and transform the ventilation system un-der the current situation,so as to achieve the effect of energy saving and consumption reduction and provide scientific basis for the transformation of the main fan of the west air shaft.
