What are the requirements for applying for the Coal Safety Certification and Mine Safety Certification?
Coal Safety Certification and Mine Safety Certification are mandatory certifications for mining products and equipment.
Coal safety certification is for equipment used in coal mines, while mine safety certification is for non-coal mine equipment. Both are applied for, reviewed, and certified by the Safety Standard Center.
Certificates are valid for 5 years and must undergo supervision and review annually.
Applying for coal safety and mine safety certifications requires passing two stages: product testing and factory audit. Applicants must have the ability to design and develop, provide complete product design drawings, and own a production factory.
Some products can also apply for coal safety and mine safety certifications through OEM.
If dealers or end-users do not meet these requirements, they are not eligible to apply for the Coal Safety and Mine Safety certification.

Do I still need a Coal Safety Certificate if the product already has an explosion-proof certificate?
The explosion-proof certificate and coal safety certificate are applicable to different locations.
Explosion-proof certificates generally refer to facilities used in places where explosive gases and dusts are present, excluding coal mine shafts.
Coal Mine Safety Certificate refers to the safety certification mark for equipment and products used 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-mining explosive gas and dust environments, a防爆 certification is sufficient.
If coal mine operations are involved, a coal safety certificate is mandatory; the two certificates are not interchangeable.
