en.Wedoany.com Reported - China's coal producer Shendong Coal Group recently completed the intelligent upgrade of the train loading cleaning system at its Jinjie Coal Preparation Plant's washing center and put it into operation. The system consists of a main lifting mechanism, a multi-directional cleaning device, a LiDAR vehicle recognition device, and an intelligent control system centered on a Programmable Logic Controller (PLC). It aims to solve the problem of cleaning residual coal particles on the car sides, replace traditional manual operations, and adapt to multiple models of railway open-top wagons such as C64 and C70. The equipment can operate stably in environments ranging from -30°C to 40°C and features dust-proof and anti-static capabilities.
Shendong Coal Group is a key coal production subsidiary of CHN Energy. Construction began in 1984, and it is located in the energy-rich region spanning Shanxi, Shaanxi, and Inner Mongolia, undertaking the major task of shifting the national energy strategy westward. The company primarily engages in coal production, washing, and processing, with main products including coal for raw materials and high-quality steam coal, characterized by low sulfur, low phosphorus, low ash, and medium-to-high calorific value. As of the end of January 2026, the company had cumulatively produced 4.153 billion tons of coal. In 2025, Shendong Coal's annual output reached 190.48 million tons, including 161.66 million tons of self-produced coal. Its 13 mines have a certified production capacity of 174 million tons, total assets of 137.161 billion yuan, and currently employ 33,073 people.
Among China's general-purpose railway open-top wagons, the C64 is a traditional model with a load capacity of about 61 tons; the C70 has a load capacity of 70 tons and a volume of 77 cubic meters, making it the mainstream model for coal transportation. The new system is equipped with LiDAR, enabling precise vehicle model identification and adaptive adjustment of cleaning positions to suit multiple car types. The system features one-button start/stop and fully automated operation, integrating multiple protection mechanisms such as flexible collision avoidance and precise limit positioning, and is linked with the central control system to achieve automated car side cleaning. The modular design reduces maintenance time and allows seamless integration with existing loading systems into the plant's intelligent management and control framework. According to relevant technical personnel from Shendong Coal, the system reduces labor costs by replacing manual cleaning, recovers residual coal particles to lower material loss, improves cleaning efficiency and overall outbound loading efficiency, reduces equipment maintenance costs, and achieves long-term cost reduction and efficiency gains. The plant will continue to advance technological upgrades in production processes and further deepen intelligent loading transformation.
