Abstract:

This paper deals the monitoring of blast hole drilling which can be used to measure drilling parameters and the difficulties encountered when using various condition. The analysis inspect the technologies used before, during, and after drilling rotary rig operation which shape everything into accounts productivity results. The research also reviews the parameter as well as reasons to increase efficiency of drill and where the industry is headed in the future. When there is a difference in drilled hole diameter or fragmentation detailing, changes in the blasthole design parameters are required affecting the cost of a drilling operation. Finally, the paper provides information aimed at resolving a problem for analysts and modelers when it is applied to make more efficient drilling operation.
