摘要
为解决随着生产的推进综采工作面风量不足、风阻增大的问题,在对东翼采区通风现状分析的基础上,对采煤、掘进工作面,硐室以及其他巷道的实际需风量重新核算,重新完成通风机的选型设计,并根据所选型的通风机配套相匹配的变频器。通过工程应用验证了通风机技术改造的效果,达到预期目的。
In order to solve the problem of insufficient air volume and increased wind resistance at the comprehensive mining workings as production progresses,the actual air demand at the coal mining and excavation workings,chambers and other roadways was re-accounted for on the basis of an analysis of the current ventilation situation in the East Wing mining area,and the design of the ventilator selection was completed again.The design of the new ventilation fan is based on the design of the new frequency converter.
