China's first self-developed heavy-duty scraper conveyor system, featuring 3 × 700KW power, an hourly capacity of 3,500 tons, and a transport distance of 300 meters, along with high-power transfer machines and a complete set of crushing equipment, has recently been successfully developed by China Coal Group Corporation. The system has passed factory inspection and is set to be deployed soon. This breakthrough fills a critical gap in the transportation equipment for fully mechanized mining faces that are over 300 meters long and more than 5 meters high in coal mines across China. It marks a significant milestone in the localization of key coal mining equipment, enhancing mine efficiency and production capabilities, and holds great importance for the future development of the industry.
Designed to meet the demands of fully mechanized mining faces exceeding 5 meters in height and with an annual output of 6 million tons, this equipment is characterized by its high power, large capacity, and exceptional reliability. For the first time, it incorporates a high-power planetary gear reducer, a compact, high-strength circular chain (φ48×152), an integrated cast-welded middle trough measuring 1.75 meters in length, a telescopic transmission tail, and high-strength forged tooth-type components—technologies that place it at the forefront of domestic innovation. The system also features advanced control systems such as hydraulic tight chain mechanisms and friction-limiting clutches.
In addition, this equipment introduces real-time monitoring technology for the working conditions of the scraper conveyor, enabling accurate tracking of lubricating oil temperature, bearing temperature, and cooling water usage. This provides essential data and technical support for early fault detection and the automation of mining operations, significantly improving the reliability and safety of the conveyor system.
