Good News｜China Coal Group Renews MA Certificates for 7 Mine‑used Electromagnetic Starters

Recently, China Coal Group has made important progress in qualification certification. Seven models of mine‑used electromagnetic starters of the Group have successfully passed the review by the National Mining Products Safety Mark Center. The MA certificate renewal work has been fully completed, and brand‑new safety mark certificates for mining products have been issued. This further consolidates the market access qualifications for mine‑used electrical equipment and enhances the market competitiveness of products.

Mine‑used electromagnetic starters serve as core control equipment for underground coal mine power supply systems, undertaking key functions including motor start‑stop, overload protection and short‑circuit protection. The MA certificate is a mandatory access credential for mining equipment applied in underground coal mines. The renewal process imposes strict assessment standards on product technical consistency, production management systems and safety performance indicators. For this MA renewal of seven electromagnetic starters, multiple assessment procedures were carried out including document verification, technical difference evaluation and on‑site production audit. All technical parameters and explosion‑proof performance of the products meet the current coal mine safety industry standards. The validity period of certificates has been successfully extended, supporting legal and compliant market sales and project supply of this product series.

For a long time, China Coal Group has strictly observed the safety bottom line of mining products, and integrated compliance construction into the whole process of product R&D, manufacturing and quality inspection. The Group keeps improving the quality control system, promotes technical iteration of mine‑used electrical products, and manages products in strict accordance with safety mark specifications. It continuously optimizes the reliability and environmental adaptability of electromagnetic starters to satisfy complex operating conditions in various underground coal mines. Up to now, the Group has built a diversified MA qualification portfolio for mining equipment, covering multiple equipment segments such as support, transportation, safety protection and electrical control, and provides complete sets of compliant mining equipment solutions for coal mine customers at home and abroad.

The successful MA certificate renewal for seven models of electromagnetic starters consolidates the Group’s qualification advantages in mine‑used electrical equipment. Going forward, China Coal Group will further focus on the mining equipment sector, pursue technical innovation alongside safety and compliance, continuously improve product quality, and upgrade mine‑used electrical product series. It will deliver more reliable equipment for safe production in the coal industry and facilitate high‑quality development of the mining sector.
