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 Marking 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 approach. To enhance coal mine safety, there is an increasing emphasis on safety technology development. The funding methods for technological development have been reformed. Due to insufficient safety investment, 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.
