Application Summary AI generated

This standard specifies the general matching requirements for equipment and systems used in fully-mechanized top coal caving mining faces operating in deeply inclined coal seams (typically with dip angles above 25°). It is applied in the Chinese coal mining industry to ensure the coordinated operation of shearers, hydraulic supports, and conveyors under high-inclination conditions, addressing stability, safety, and efficiency challenges. The standard serves as a technical reference for mine design, equipment selection, and operational validation in steeply dipping underground coal mines.
