矿井开掘巷道“三风机、三电源”自动倒台系统研究

Resea rch on "three fans, three power supplies" Automatic Fall System of Mine

本文主要介绍了通过对矿井掘进工作面局部通风机进行技术改造,改变原风机控制方法,克服原控制方法的缺陷,(主、副风机自动倒台运行,但当第三风机突然失电跳闸,其它风机不能自动开启),确保只要有一台风机电源恢复,将会自动开启,使采掘工作面局部通风机连续运行。

This paper mainly introduces the technological transformation of the heading face of mine fans with the help of changing their original control method. As a result, the defects of the original control method are overcome（Main and auxiliary automatic fan are in operation, but when the third fan loses power suddenly, other fans can not open automatically）. As long as there is a fan power restored, it will open automatically and ensure the mining work face running constantly.
