世界首台，我国自研，成功下线

Core Viewpoint - The successful development of the world's first 10 kV powered intelligent coal mining machine marks a significant technological advancement in the coal mining industry, enhancing power supply efficiency and supporting the transition to larger and more intelligent mining operations [1][2]. Group 1 - The 10 kV powered intelligent coal mining machine was jointly developed by Shaanxi Coal Heavy Industry Group and National Energy Group, and it has successfully passed factory evaluation [1]. - This machine is designed for large and super-large intelligent mines, addressing the limitations of the previously used 3.3 kV powered machines, which were common in the industry [1]. - The transition from 1.14 kV to 3.3 kV machines took over a decade, while the development of the 10 kV machine was achieved in just two years, showcasing rapid technological progress [1]. Group 2 - The coal mining industry in China is increasingly moving towards intelligent and large-scale operations, with over 80% of total production now coming from large mines producing 1.2 million tons or more [2]. - The introduction of the 10 kV powered machine enhances the safety and quality of power supply in mining operations, reduces energy waste, and is crucial for the upgrade of industry equipment [2]. - The growth in the number of intelligent mining faces has increased from over 400 to around 1,600 since the start of the 14th Five-Year Plan, indicating a significant shift towards automation and efficiency in the sector [2].
