Abstract: In order to study the relationship between the automatic drilling parameters of LWD-200B type cutting drilling machine and rock properties in the open-pit mine, the mine collects the real-time data related to the lithology by drilling parameter recorder in the field, and identifies the nature and location of different rocks through observing and analyzing debris in the drilling process. Using decision tree CHAID model of Clementine software, the article carries out statistical analysis on drilling parameter, and predicts the rock distribution of work platform.
