I. Specialized regular meetings at the Wangjiaying Qingli Coal Mine, covering “Mechanical and Electrical & Transportation,” “Roof Management,” “Ventilation, Gas Control, and Fire Prevention,” “Safety Office Work,” “Mechanical and Electrical & Transportation,” “Water Control,” and other topics.

(1) 2026 year 3 month 30 On [date], our mine convened a special routine meeting covering key areas such as geological surveying and water control, flood‑season prevention, roof management, ventilation and gas control, safety administration, and mechanical, electrical, and transportation systems. The meeting was chaired by the mine’s top leadership, with attendance from members of the mine’s leadership team, heads of all functional departments and work teams, and on‑site supervisors.

(II) During the meeting, the heads of each business unit systematically reported on their recent work, comprehensively reviewing the implementation status of key tasks including geological and surveying monitoring, water hazard identification, flood‑prevention preparations, roof‑control management, ventilation systems, gas and dust prevention, safety inspections, and mechanical, electrical, and transportation maintenance. They also conducted an in-depth analysis of the weak links and prominent hazards currently present in on‑site operations. Drawing on the mine’s actual production conditions, the meeting specified corrective measures, assigned responsible personnel, and set completion deadlines for each issue, while meticulously planning the next phase of activities, such as forecasting and early warning, flood‑season duty rosters, emergency drills, roof‑inspection patrols, ventilation optimization, fire and dust control, closed‑loop management, and equipment risk prevention.

(3) The meeting clearly mandated that all levels of the mine must firmly assume and rigorously enforce safety responsibilities, strengthen on-site supervision, strictly implement established systems and measures, closely monitor critical processes and vulnerable areas, conduct routine hazard inspections, and resolutely prevent any violations. This meeting further aligned the entire workforce on safety priorities, clarified operational guidelines, reinforced hierarchical accountability, and effectively enhanced the mine’s overall prevention and control capabilities as well as its safety management, thereby laying a solid foundation for the steady and orderly advancement of safe production going forward.

II. 15301 Production Status of the Fully Mechanized Mining Face

(1) The 15301 fully mechanized mining face has a designed recoverable strike length of 570 m, an average coal seam thickness of 2.2 m, and a bulk density of 1.52 t/m³. As of the mid-shift on April 16, 2026, the face has achieved an average advancing distance of 122 m, with remaining recoverable reserves of 215,000 tonnes.

(II) At present, the efficient and stable production at Working Face 15301 has propelled the mine’s overall operations into a virtuous cycle. Cash flow has improved fundamentally, and all supporting systems are operating with comprehensive stability. This not only addresses, at its root, the long-standing challenge of capital turnover but also enables the mine to fully restore operational stability across all areas—safety‑related investments, equipment maintenance, logistical support, and more—thereby placing the entire operation on a path of positive momentum. As a result, the mine’s operational safeguards—including production, equipment management, and logistics—have entered a steady, reliable, and self‑reinforcing cycle. This marks a solid step forward on our journey toward a safer, more efficient future.

III. Conditions at the Tunneling Face

(1) The 15105 return airway (EBZ-280) heading machine has been installed, and the 15105 cut‑eye site now meets all safety requirements for commencement of work. At present, the 15105 cut‑eye is undergoing normal widening and lining operations.

(2) The continuous miner for the 11B roof drainage return airway has been replaced and installed; it is expected to reach its design advance position by the end of the month.

(3) The proper installation and transportation of the EBZ-280 roadheader will significantly accelerate progress in the mine’s mining‑driving succession, the northern wing development project, and the gas control program, thereby alleviating the strain on mining‑driving continuity.

IV. Organizing On-site Meetings for Key Projects

According to 49 The provision stipulates that, 4 During the month, underground operations were organized to construct the new ventilation shaft. 15105 Adjustment of the ventilation system in the transport roadway, 15301 Site meeting on the passage of a mining face through a geological structure.

V. Employee Training Status

The Safety Department utilizes training sessions to provide employees with cautionary education and skills‑based training. This has significantly enhanced workers’ proficiency in operational skills and their awareness of safety, fostering a proactive commitment to safety and elevating the mine’s overall safety management standards.
