What are the requirements for obtaining 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.
Application for Coal Safety Certification and Mine Safety Certification requires both product testing and factory inspection. Applicants must possess design and development capabilities, provide complete product design drawings, and own a production factory.
Some products can also apply for Coal Safety and Mine Safety certifications through the OEM process.

Basic Process and Agencies for Coal Safety Certification
Coal Safety Certification is a mandatory safety certification for equipment and products used underground in coal mines. It follows a "Product Testing + Factory Audit" approach, which involves both testing the application products and conducting on-site audits and annual supervisory reviews of the production factories for those products, which is commonly referred to as factory inspection.
The product testing aspect requires compliance with coal safety standards, such as electrical products needing to meet explosion-proof requirements in coal mine gas environments, as well as product performance requirements.
Factory audits primarily focus on the evaluation of the factory based on the ISO9001 production quality system, further combined with the requirements of the Mine Products Safety Mark Implementation Rules. The Safety Mark Center is the certification and inquiry institution for coal safety marks.

With a team of explosion-proof technology engineers and factory audit specialists, we can facilitate enterprises in applying for coal safety certification conveniently and quickly.
