煤矿供电采用双回路供电线路，以保证供电的连续性和可靠性。正常情况下双回供电线路采用分列运行方式，一回路运行时另一回路带电备用。当工作回路发生故障中断供电时，备用回路应能立即投入运行。但在煤矿生产过程中，由于极端的气候异常会导致双回路同时停电。本文通过强风引起煤矿双回路同时停电事故的原因分析，提出了预防同类大面积停电事故的措施。
煤礦供電採用雙迴路供電線路，以保證供電的連續性和可靠性。正常情況下雙迴供電線路採用分列運行方式，一迴路運行時另一迴路帶電備用。噹工作迴路髮生故障中斷供電時，備用迴路應能立即投入運行。但在煤礦生產過程中，由于極耑的氣候異常會導緻雙迴路同時停電。本文通過彊風引起煤礦雙迴路同時停電事故的原因分析，提齣瞭預防同類大麵積停電事故的措施。

The coal mine power supply using double circuit power supply circuit, In order to ensure continuity and reliability of power supply. Normally double power supply circuit using parse mode of operation, The primary operation the other primary charged spare. When work circuit malfunction interrupt power supply, Spare circuit should be able to immediately put into operation. But in coal mine production process, due to the extreme climatic anomaly can lead to double circuit and power outages.This paper analysed reason of large area blackout accident in coal mine because of strong breeze. The precautionary measure was presented.
