Recently, Shandong China Coal Group has achieved another important breakthrough in qualifications. The ZGJFH35 and ZGJFH50 underground automatic explosion isolation devices submitted by the Group passed the review and were granted the Safety Mark (MA) Certificates for Mining Products. The acquisition of the two qualifications further improves the Group’s product line of underground explosion-proof safety equipment, creates synergy with existing coal safety certified products, and consolidates the Group’s market position in the field of mine safety equipment.
The two newly approved underground automatic explosion isolation devices are developed and manufactured in accordance with KA/T694-1997 and special corporate technical standards. Adopting an all-mechanical structure, they can rapidly block the propagation of gas and coal dust explosions in underground coal mines and curb disaster escalation, serving as essential core safety equipment for underground disaster prevention and mitigation. Shandong China Coal Group has always attached great importance to product compliance, and continuously promoted standardized R&D and lean production of mining equipment. Drawing on years of experience in mine equipment research and development, the Group now boasts a wide range of coal safety certified products covering hydraulic support, transportation and hoisting, ventilation and safety protection, intelligent measurement and control, forming a complete and coordinated qualification system for mining equipment.
The successful acquisition of coal safety certificates for the two automatic explosion isolation devices strengthens the Group’s qualifications for underground explosion isolation and protection equipment. Together with the Group’s existing certified safety products for ventilation, dust suppression and outburst prevention, they form integrated supporting solutions. This enables the Group to deliver all-in-one mine safety equipment solutions for coal mining enterprises, break away from the single-product sales model and enhance overall business competitiveness.
Going forward, Shandong China Coal Group will continue to focus on the safety production demands of mines, advance both technological innovation and quality control, expand the range of mining safety equipment, and steadily push forward applications for coal safety certification of more new products. With a sound qualification system and reliable product quality, the Group will keep supplying safe, efficient and intelligent mine equipment to coal enterprises at home and abroad, facilitating high-quality development of safe coal mine production.
