摘要
由于煤矿井下供电系统没实现双回路电源供电,供电系统不可靠,局部通风机常常发生停电停风事故,造成采、掘工作面瓦斯超限和积聚,经通过对供电系统改造和采取措施,大大减少了由于停电停风所造成的瓦斯积聚和超限事故。
Because the coal mine mine shaft power supply system has not realized the double return route power supply,the power supply system is unreliable,the partial ventilator frequently has the power cut and the wind cut accident,creates picks digs the working surface gas to ultra limit with the agglomerating passes through transforms and takes the measure to the power supply system greatly reduced because power cut and wind cut the gas agglomeration and ultra limits which creates the accident.
