Coal Safety Certification is the abbreviation for Coal Mine Safety Certification.
In 2007, the Economic and Trade Commission and the Coal Mine Safety Supervision Bureau issued documents such as the "Temporary Measures for the Safety Mark of Coal Mine Products," implementing a safety production certification system for equipment, instruments, and meters used in underground coal mines, effectively preventing substandard products from entering the mines. The safety production marking system is an effective method. To enhance coal mine safety, there is an increasing emphasis on safety technology development. The funding approach for technology development has been reformed. Due to insufficient safety investments, a financial guarantee mechanism for safety production research and development should be established.
Therefore, all types of equipment and products used in coal mine underground must pass the safety certification system of the Safety Standardization Center and obtain the corresponding coal safety certification.

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 require annual supervision and review.
Applying for both Coal Safety Certification and Mine Safety Certification requires passing two stages: product testing and factory audit. Applicants must have design and R&D capabilities, provide complete product design drawings, and possess an independent production facility.
Some products can also apply for Coal Safety and Mine Safety certifications through the OEM process.
If distributors or users, among others, do not meet these qualifications, they are not eligible to apply for the Coal Mine Safety and Coal Safety Certification.

What explosion-proof certifications are required for explosion-proof products? What are the institutions for applying for explosion-proof certifications?
Currently, the certification models for explosion-proof products entering the Chinese market are primarily three in number.
1. Obtain explosion-proof certificates for equipment used in environments with explosive gases and combustible dust in non-coal mines, which only requires product testing; upon passing the test, the certificate is issued.
2. Obtain explosion-proof 3C certification; for products listed under the explosion-proof 3C category, product testing and factory inspections are required.
3. Coal Mine Safety Certification, for explosion-proof equipment used underground in coal mines, featuring a certification process that includes product testing and factory audit.
