Recently, China’s first 10-kilovolt (kV) high-voltage powered coal mining machine rolled off the production line in Shaanxi Province, marking a significant breakthrough in intelligent mining equipment technology. Independently developed by a leading domestic mining machinery manufacturer, this machine utilizes a 10 kV direct power supply system. Compared to conventional 6 kV systems, it significantly reduces transmission losses, improves energy efficiency, and decreases both cable usage and equipment size—enhancing safety and operational efficiency in underground mines. This innovation not only meets the demand for high-power, highly reliable equipment in large-scale modern mines but also provides crucial technical support for the coal industry’s green and low-carbon transformation. Experts note that the successful development of this 10 kV-powered mining machine will accelerate the construction of smart mines in China and contribute to optimizing the nation’s energy structure under its ‘dual carbon’ goals. The equipment has already passed multiple safety and performance tests and is set for trial operation in key mining areas in Shaanxi.
近日，中国首台10千伏高压供电采煤机在陕西省正式下线，标志着我国煤矿智能化装备技术取得重大突破。该采煤机由国内领先矿山装备企业自主研发，采用10千伏高压直供系统，相较传统6千伏供电方式，可显著降低输电损耗、提升能效，并减少电缆使用量和设备体积，从而提高井下作业的安全性与效率。这一创新不仅满足了大型现代化矿井对高功率、高可靠性设备的需求，也为推动煤炭行业绿色低碳转型提供了关键技术支撑。专家指出，10千伏供电采煤机的成功研制，将加速我国智能矿山建设进程，助力实现‘双碳’目标下的能源结构优化。目前，该设备已通过多项安全与性能测试，即将在陕西重点矿区投入试运行。
