Abstract:

Mine explosion-proof electrical equipment is a common explosion-proof electrical equipment, and is widely used in underground coal mine electrical equipment with the characteristics of realizing easily, the notable explosion-proof effect , and low cost. The quality of the product plays a critical role to the personal and property safety which underground explosive gas environment. This article described the common problem in the process of checking flameproof electrical drawings, elaborated the methods of checking the flameproof parameters in details. strict review of the drawing is not only conducive to improve the quality of products, but also has vast importance to ensure coal mine safety production.

Key words: Explosion- proof, electrical equipments, flameproof joints, explosion, explosion parameters, review
