Abstract: This paper analyzes the current research status of digital platforms for underground coal mine drilling in China from three aspects: digitization of measurement while drilling, digitization of drilling site environment monitoring, and digitization of drilling rig monitoring. Combined with the actual needs of intelligent drilling in coal mines, the overall architecture of the digital platform for directional drilling in coal mines was designed, and the connotation and path of key technologies such as multi-sensor data fusion and remote interaction were analyzed. The engineering practice of related technologies was carried out in Tianrong Coal Mine of Wuhai Mining Area, and the comprehensive management and control capability of the digital platform for drilling was verified through the trial operation system. Finally, it points out the digital development trend of directional drilling in coal mines.
