Development of a fuzzy model for predicting the penetration rate of tricone rotary blasthole drilling in open pit mines


The effects of rock mass parameters on the choice of the type of tricone bits were investigated by Kricak (1997). Today there are a number of rotary blasthole drill rigs designed for use in soft and hard rock formations with a wide range of drilling parameters adaptable to specific drilling conditions. Drills have large size and high weight and their masts… (More)
