Patent ID: 8210278

Claim:
A method for drilling rock comprising: prior to drilling, determining a drilling pattern of holes to be drilled, wherein the drilling pattern includes, for each hole, a starting place, direction and hole depth for drilling determined with respect to the rock to be drilled, the holes provided in the drilling pattern being grouped into at least two different hole types according to the purpose of a hole, and wherein each hole type includes more than one hole, determining an accuracy requirement for each hole type; determining hole-type-specific drilling parameters based on the accuracy requirement for each hole type in the drilling pattern, determining, for each hole in the drilling pattern, the hole type, and storing the hole-type-specific drilling parameters and drilling pattern in a memory of the drill rig; and during a drilling phase, the drill rig automatically selects the drilling parameters for each hole on the basis of the hole type of the hole being drilled by: determining the hole type of the hole from the drilling pattern stored in the memory of the drill rig and selecting from the memory of the drill rig, the hole-type-specific drilling parameters that correspond to the determined hole type of the hole.
