For the mine and other explosive areas (workshop) appliances. Various appliances used in the mine, in the normal operation or failure will generate a spark, arc or dangerous temperature rises, which are likely to be an ignition source and cause gas explosion. Explosion-proof electrical design and manufacture according to specified conditions, and to take all measures to put an explosive mixture around the ignition source and isolate to prevent explosion caused by an explosive mixture around.

There are three types of electrical explosion.

① Explosion: There flameproof enclosure, able to withstand the internal pressure generated by explosive gas mixtures, and prevent the spread of an internal explosion of an explosive mixture to the surrounding shell. Various electrical appliances are loaded flameproof enclosure. To improve the ability of proof, can be vacuum appliances.

② filled type: All or part of the electrical parts immersed in the oil, so that electrical ignition source can not point an explosive mixture of fuel surface above or outside the shell.

③ intrinsically safe: EDM and thermal effects in normal operation or under fault conditions are required to produce an explosive mixture does not ignite prescribed. Various types of explosion-proof electrical explosion undergo the strict testing and compliance with the relevant standards, to ensure the safety of use. There is usually necessary proof mark and technical data on the proof electrical equipment, in order to avoid misuse.
