... in different rock types. Subsequently, thin sections of the bottom of the borehole were analyzed to get the associated crack patterns. Based on that, the attempt was made to simulate the drilling process in a specific rock material with the Particle Flow Code (PFC). Since the code is based on the discontinous...

Paper presented at the 1st Canada - U.S. Rock Mechanics Symposium, May 27–31, 2007
Paper Number: ARMA-07-025
... ABSTRACT ABSTRACT: This paper introduces a new in-situ technique for characterizing rock mass mechanical strength and the associated spatial distribution in the ground. The technique involves automatic drilling process monitoring (DPM). Case examples are given to show the original DPM data...
