As open-pit coal mines reach greater depths, the coal industry is turning to larger, more powerful equipment and digital technologies to improve mining operations. Modern machinery is helping companies extract and transport coal more efficiently, reduce operating costs and ease the physical demands on workers, while improving safety, boosting productivity and making mining operations more efficient overall.
Open-pit coal mines in Quang Ninh have reached greater depths, making mechanisation and the use of high-capacity equipment increasingly essential to improve productivity, efficiency and safety.At mining sites, large electric excavators work alongside high-capacity haul trucks to improve the efficiency of rock and soil removal and transportation, while reducing equipment waiting times.Cao Son Coal Joint Stock Company is expanding the coordinated use of large excavators and high-capacity haul trucks to optimise equipment performance, boost productivity and reduce mining costs.

Along the open-pit mine roads of Deo Nai-Coc Sau Coal Joint Stock Company, heavy-duty haul trucks continuously transport coal, rock and soil to meet production demands as mining operations reach greater depths.In order to ensure the safe operation of heavy-duty equipment, workers carry out thorough technical inspections before every shift to identify and address potential safety hazards.Like haul trucks, large excavators also undergo regular on-site inspections and maintenance to prevent breakdowns and keep mining operations running smoothly.Workers at the Electromechanical Equipment Repair Workshop of Deo Nai-Coc Sau Coal Joint Stock Company carry out repairs on mining equipment, helping ensure reliable machinery performance and safe, uninterrupted production.
Beyond boosting productivity, mines are also using specialised equipment to protect the environment. Pictured is a CAT 773E-GF13W water-spraying truck suppressing dust at the Ha Tu Coal Mine, helping reduce airborne dust during mining operations.Coal is loaded and transported from the mining site to storage yards using high-capacity wheel loaders.The large-scale stacker, reclaimer and conveyor systems at Cua Ong Coal Preparation Company help mechanise coal stockpiling and storage management, reduce material handling stages and improve production efficiency.From the storage yards, coal is continuously transported by conveyor belts to the loading area to meet customer demand.
The Cua Ong port system, equipped with modern coal-loading facilities, helps increase coal handling capacity and ensure a reliable energy supply for industrial production and socio-economic development.
