Research on Intrinsically Safe of Coal Mine Electrical Equipment

In this paper,taking the mine lighting and power supply cable as an example,points out that in the mine pit production was used in which electric equipment can effectively avoid electric spark caused by gas,coal dust explosion.Combination of coal mine safety regulations analysis of various lighting specifications characteristics and safety requirements,finally obtains the conclusion,in order to mine production safety,avoid the accident,to use mine intrinsically safe electrical equipment.
