Abstract：Against the backdrop of global energy transition and the"dual carbon"goal of China,the coal mining industry is undergoing a pivotal shift from traditional mechanization and automation to intelligent systems in China.A comprehensive overview of the development of drum shearers and their intelligent technologies both domestically and internationally is given,which shows that,the leading manufacturers,such as Anderson(UK),Eickhoff(Germany),and Joy Global(USA),have achieved significant breakthroughs in shearer technology,particularly in memory cutting and remote monitoring;drum shearers in China,though started later,have achieved notable progress in recent years through independent innovation,particularly in high-end equipment and intelligent technologies.The key intelligent technologies of shearers are introduced across four areas:intelligent perception,intelligent control,intelligent communication,and intelligent diagnostic and maintenance technologies.The future trends are highlighted,such as high-efficiency intelligent shearer reliability assurance,intelligent high-pressure power supply systems for longwall mining,multi-source information fusion for perception and interaction,advanced artificial intelligence,digital twin technology for coalface operations,and the robotization of shearer systems.These insights provide crucial guidance for advancing shearer technology and driving the intelligent development of coal mining in China.
