Abstract:
1. A computer-implemented method for designing a drilling pattern for excavating rock, the method comprising instructions executed by a processor, the instructions comprising: determining for the drilling pattern at least a location and a hole direction angle of each drill hole in a coordinate system of the drilling pattern for a round to be drilled in the rock; positioning at least one group of holes in the drilling pattern, and several drill holes in said at least one group of holes; determining at least one master hole for the at least one group of holes in the drilling pattern; determining at least one dominating property for the at least one master hole; determining, on the basis of the at least one dominating property of the at least one master hole, a property of several other drill holes; and identifying an area of influence in the drilling pattern, the area of influence comprising one or more drill holes influenced by the at least one master hole, wherein the at least one master hole is editable to be added or removed and to change a dominating property, wherein the at least one dominating property is selected from the group consisting of a location in the at least one group of holes, a depth, a hole direction angle, a degree of charge, and a hole interval, and wherein the area of influence includes a predetermined number of drill holes closest to the at least one master hole, or drill holes at a predetermined absolute distance from the at least one master hole.
