Abstract

The functions of drilling parameter monitor(ZCY),including real-time automatic detection,display,drilling parameter and dynamical change curve recording,as well as alarm display for some key parameters go beyond limit are introduced.Its actions in coal seam drilling,hydrogeologic monitoring,hole accident avoiding,safety operation and drilling speed improving are analyzed.
