Abstract: Intelligent drilling is the technical basis for the intelligent mine geotechnical engineering, and the prior conditions for information construction of rock and soil engineering.It has an abroad application prospect in fields of mine rock and soil engineering, geotechnical engineering, geological engineering and earth scientific drilling.The major components, key techniques as well as technical bottlenecks of the intelligent drilling, including principal constitution and fundamentals, monitoring in drilling, positioning and navigating of drilling bit, signal transmission, real-time identification and classification of lithizone are introduced.And building the real-time identification and classification theory of intelligent drilling, completing the software and hardware systems of information wire transmission with intelligence drilling, and realizing the continuous monitoring, analysis, evaluation, control and management on stratum and drilling system are the development directions in future.

Key words: Intelligent drilling, Bit positioning, Signal transmission, Identification and classification of stratum
