The majority of the coal products produced and sold by the Group were thermal coal. The Group has independently operated railway transportation channels for collection and distribution. These channels concentrated in the vicinity of self-owned core mining areas, and can satisfy the transportation needs in the core mines. In 2025, the Group resolutely shouldered the responsibility of securing energy supply, further promoted the “safe, green, efficient and intelligent” coal mining model, organized production in a scientific manner and strengthened coordination and collaboration, thereby continuously improving production efficiency and maintaining stable and high-quality output of selfproduced coal.

The green and intelligent coal mining capabilities have continued to improve. Adhering to green development, the Group has vigorously promoted the construction of green mines. Fifteen coal mines of the Group have been included in the national green mine list, and eight in the provincial green mine list, accounting for 82% of the Group’s total coal mines. Adhering to innovation-driven development, the Group has advanced the high-quality intelligent transformation and upgrading of coal mines. By the end of 2025, all underground mining faces of the Group have achieved intelligent operation; fixed posts such as underground substations, power distribution points, pump rooms, and main transportation systems have achieved unmanned operation; more than 350 sets of auxiliary operation robots have been developed and applied for inspection, monitoring and heavy physical labor replacement; more than 450 sets of unmanned trucks, unmanned electric shovels, and unmanned auxiliary equipment have been applied in open-pit mines; and all coal preparation plants have achieved intelligent operation.

The coal sold by the Group is primarily produced from its self-owned coal mines. In order to fulfil the needs of customers and adequately make use of railway transportation, the Group also purchases the coal from third parties in the surrounding area of the self-owned mines and along railway lines for blending into various types and grades of coal products, which are then centrally sold to external customers.
