Shenzhen Zhongnuo Testing Technology Co., Ltd. specializes in consulting services for explosion-proof certification and coal safety certification.
The domestic coal safety certification system is still quite strict. It combines type testing with factory production system review.
To ensure that the applicant company is capable of ensuring the production and capability of the products. Even after obtaining the coal safety certification,
The company must undergo an annual supervision and evaluation by the ANSI Center.

Do I still need a Coal Mine Safety Certificate if the product already has an explosion-proof certificate?
The explosion-proof certificate and coal safety certificate are applicable to different locations.
The explosion-proof certificate generally refers to locations where various explosive gases and dusts are present, excluding underground coal mines.
Coal Mine Safety Certificate refers to the safety certification mark for equipment and products used in underground coal mines.
So, whether to apply for a 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 environments, a防爆 certificate is sufficient.
If coal mine operations are involved, a coal safety certificate is mandatory; the two certificates are not mutually recognized.

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 "Provisional Measures for Safety Marks 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 a practical and effective method.
To enhance coal mine safety, there is an increasing emphasis on the development of safety technologies. The funding methods for technological development have 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.
