Abstract: Based on the analysis on the drilling technique and equipment in the available underground mines, from the measurement while drilling, status monitoring and measuring and the dilling rig control, the paper stated the domestic study status on the key technology of the digitalized drilling in the underground mine. The paper discussed the development tendency of the digitalized dilling technology in the underground coal mine and provided the accurate guide dilling, the automatic control of the drilling rig, remote fault diagnosis, itelligent management of the drilling site and other future study key point as well as the relevant realized method and key technology. Meanwhile, the paper pointed out that development direction of drilling technology and equipment in China underground coal mine.
