Explosion proof certificates and coal safety certificates are applicable to different places,

Explosion proof certificate generally refers to places used to remove various explosive gases and dust underground in coal mines

Coal safety certificate refers to the safety symbol certificate used for equipment and products underground in coal mines

So, whether to apply for an explosion-proof certificate or a coal safety certificate depends on where the product is used. If used only in non coal mine explosive gas and dust areas, having an explosion-proof certificate is sufficient. If it is necessary to use coal mines underground, a coal safety certificate is required, and the two are not interchangeable.
