Abstract

Abstract:

According to the analysis of coal mine gas explosion accidents in recent years,the main reason is that the main ventilator was unplanned outage, power supply failed to recover in time, resulting in the accumulation of gas is over the limit, eventually lead to gas explosion, which have an important influence on the safety operation of coal mine.It has been proved that, the power supply rapid switching device developed for mine, can significantly improve the reliability of power supply system, ensure the continuous operation of the ventilators, reach to the purpose of intrinsic safety in coal mine in a certain extent.

Key words: mine, rapid switching device, gas explosion, ventilator, power supply system, grade trip
