From March 22 to 23, Sun Jian (Chongqing Testing Center) and Xie Tian (Shanghai Testing Center), the expert group of National Safety Standard Mining Product Safety Mark Center Inspection Institute, went to China Coal Group to carry out on-site supervisory review on the core products independently developed and produced by the Group, such as the coal mine underground automatic explosion-proof device and the explosion-proof and intrinsically safe vacuum electromagnetic starter for mining use. After two days of strict review, the relevant products of China Coal Group passed the audit with high standards, which once again demonstrated the hard core strength of the enterprise in the field of mining safety equipment.
Authoritative Gatekeeping: All-Dimensional Strict Review To Build A Strong Safety Line Of Defense
During the evaluation, the expert group strictly followed the national safety standards for mining products and safety standard certification norms, through the four-step linkage of 'checking, looking, asking and checking', in-depth production workshops, laboratories and warehousing areas, with a focus on verifying the product design documents, process control processes, raw material quality traceability system and finished product factory inspection records. and finished product factory inspection records. For the key structural parameters of the explosion-proof device, the intrinsic safety performance of the electromagnetic starter and other core indicators, the expert group used on-site sampling, functional testing and other ways to verify, to ensure that the product from R & D to the landing of the whole life cycle in line with the requirements of safe production. Shao Hua, Executive Vice President of China Coal Group and General Manager of Manufacturing Corporation, Zang Congli, Assistant General Manager of the Group and Director of Procurement Center, Sun Qinglu, Production Director of China Coal Precision Plant, and Sun Fuxing, Production Director of China Coal Coal Mining Machinery Plant, accompanied the whole process of the verification, and carried out in-depth exchanges with the expert group on the upgrading of intelligent production line, quality risk prevention and control mechanism, and so on.
Technology Leadership: Innovative Achievements Highly Recognized By The Expert Group
During the seminar, the expert group fully affirmed China Coal Group's technological accumulation in the field of mining safety equipment, especially pointing out that its automatic explosion isolation device adopts intelligent sensing technology and rapid response mechanism at the forefront of the industry, and that the explosion isolation and intrinsically safe vacuum electromagnetic starter excels in explosion-proof reliability and other key indexes. Mr. Sun Jian, head of the evaluation team, said, 'China Coal Group has not only established a perfect quality management system, but also promotes product iteration through continuous innovation, which provides a strong guarantee for the safety of underground operations in coal mines.' The passing of this evaluation marks that the core technology of the enterprise has been endorsed by the national authority again.
Establishing Enterprise With Quality: Anchoring The New Benchmark Of Mining Safety Equipment
Mr. Shao emphasized in his concluding remarks that safety standard certification is the 'passport' of mining equipment market, and it is also the 'commitment letter' of corporate social responsibility. China Coal Group has always put 'zero-defect management' through the whole process of R&D and manufacturing, and has invested more than 100 million yuan in the past three years for the upgrading of intelligent testing equipment and process innovation. After this review, the company will accelerate the R&D of new generation of mining intelligent safety equipment, injecting strong kinetic energy for the intelligent and safe transformation of mines nationwide.
As a leading enterprise in the supply chain of mining materials in China, China Coal Group has passed the dynamic supervision and evaluation of the National Safety Standard Center for 15 consecutive years, and its products cover dozens of key coal-producing areas in China and serve more than a thousand mining units. This review not only consolidates the technical discourse of the enterprise in the industry, but also sets up a benchmark model for the high-quality development of mining equipment.
