部分矿井由于受到各方面因素影响,实际生产能力不能达到设计生产能力,有些采区安装的主要通风机的通风能力大于采区实际需要风量,即主要通风机匹配的电动机不合理,不但造成经济效益的损失,而且影响矿井的本质安全。本文以嘉禾煤矿浦溪井为例,通过简述矿井主要通风机与电动机匹配的合理改造,分析其运行效果和对矿井安全的影响;并浅述改造后的经济效益。
Due to various factors affecting some mines, the actual production capacity can not meet the design and production capacity. In some mining areas, the ventilation capacity of the main ventilator installed is greater than the actual air volume required by the mining area. That is, the motor matching the main ventilator is not reasonable, which not only brings economic benefits Of the loss, but also affect the intrinsic safety of the mine. Taking Puxi well in Jiahe Coal Mine as an example, this paper analyzes the operation effect and the impact on the mine safety by briefly describing the reasonable rebuilding of matching mine main ventilator and motor, and also discusses the economic benefits after transformation.
