Strict quality standardization management

After navigating through a challenging and turbulent period, the Yaoqiao Coal Mine in Jiangsu, China, is stepping into a new era of safety-driven development. As the largest coal mine in the province, it plays a crucial role in the company's overall production and operations, bearing half of the operational burden. Despite facing severe market conditions, aging infrastructure, complex geological challenges, and increasing pressures from deep mining, the mine remains committed to its mission of ensuring a safer future.

Embracing the path of quality standardization

In response to these challenges, the mine has taken proactive steps to enhance its quality standards. By integrating refinery management practices with on-site operations, the mine has extended its quality control efforts to every corner of the mining area, including work faces and individual job positions. The principles of "safety, firmness, beauty, economy, and practicality" guide this initiative, aiming to create a unique standardization model that reflects the "Yaoqiao characteristics." Through the implementation of a six-dimensional management approach—proceduralization, workflow standardization, normalized quality supervision, linearized pipelines, equipment responsibility, and material coding—the mine has significantly improved its operational efficiency. Additionally, the coal lane teams have adopted a "five-line management" system, while rock lane teams focus on precision in installation and spraying. These efforts have not only enhanced the visual quality of the site but also strengthened employees' awareness of compliance and quality.

Walking the road of standardized safety behavior

The mine has long emphasized human-centered safety management. It has established a clear safety responsibility system, creating a "level 1 package, level 1 to level 1" management mechanism. Initiatives such as party member safety patrols, setting up "safety red lines," finger spelling, mentorship, and confessions have helped workers understand their responsibilities and how to perform them safely. The helmet numbering system ensures that each employee’s identity is clearly marked, serving as a long-term ID for monitoring and accountability. The mine also produces and screens demonstration videos to correct unsafe behaviors and improve operational skills. Regular lectures by experienced personnel further enhance frontline workers’ safety awareness and technical proficiency.

Advancing the road of technological innovation

To ensure sustainable and safe operations, the mine has embraced a science and technology-driven strategy. It continuously adopts advanced technologies, processes, equipment, and materials that are both high-tech and reliable. This has led to significant upgrades in the mine’s technical capabilities and improved disaster prevention measures. Each year, over 20 innovative projects are implemented, providing critical support for safety and quality. For instance, the mine introduced an advanced anti-finger device for high-angle coal roadways, enhancing worker safety. In deep excavation, pressure relief holes and improved fire prevention systems have reduced risks. A self-propelled drilling rig now requires only two operators instead of four, doubling the speed. These innovations have not only improved efficiency but also made the mine safer and more reliable.

Improving the working environment

The mine prioritizes the health and well-being of its workers. It has installed high-pressure automatic sprayers and secondary negative pressure dust removal systems on coal mining machines, ensuring that dust levels are minimized during operations. Automatic sprays are triggered when moving or lowering supports, reducing dust concentration effectively. In the Yanxiang team, automatic spray guns and feng shui devices have been deployed, significantly improving air quality after blasting. Explosion-proof water suppression systems have also been installed in main intake and return airways, solving issues related to power outages and safety risks. Additionally, an automated minecart washing system has been developed, ensuring cleaner air flow and a healthier workplace. The introduction of mechanized transport systems has reduced physical strain on workers, contributing to a safer and more comfortable working environment.
