Mine‑use cameras fall into the category of explosion‑proof surveillance products, representing an intersection of the explosion‑proof industry and the surveillance industry. Therefore, mine‑use cameras are a type of explosion‑proof camera. Nevertheless, explosion‑proof cameras serve a broader range of applications, while mine‑use cameras are exclusively designed for underground mine environments. Since no dedicated product implementation standards are available for other types of mining enterprises, coal‑mine standards are adopted for the procurement of underground video‑monitoring equipment. Below, our editor from Kaimorui introduces the mandatory certification documents required for mine‑use cameras.

The mandatory certifications for mine‑use cameras are listed as follows:

1. Explosion‑proof Certificate: Issued by the explosion‑proof testing center affiliated to the National Electrotechnical Commission, with the explosion‑proof marking Exd Ⅰ.
2. Production License (for Explosion‑proof Electrical Apparatus): Issued by the General Administration of Quality Supervision of the People’s Republic of China.
3. In accordance with documents including the Interim Measures for Safety Marks of Coal‑Mine Products, issued by the former State Economic and Trade Commission and the State Administration of Coal Mine Safety Supervision in 2007, equipment deployed in the coal‑mining sector, especially underground coal‑mine sites, must hold a Safety Mark Certificate for Mining Products before being permitted for underground operation. This certificate is granted by the National Office for Safety Licensing of Mining Products.

That concludes our sharing. The mine‑use camera is video‑surveillance equipment for image acquisition and transmission in critical underground coal‑mine locations. It applies to underground coal‑mine sites with explosive gas mixtures such as methane and hydrogen.
