A method for determining wear of a drill bit is disclosed. The method includes drilling a first hole in a worksite based on a hole pattern having a plurality of planned holes and determining an energy required to drill the first hole. The method also includes drilling a second hole in the worksite and determining an energy required to drill the second hole. The method further includes determining a wear of the drill bit using the determined energy required to drill the first hole and the determined energy required to drill the second hole.

Method and apparatus for detection of drill bit wear

A method for sequencing drill holes for a mobile drill rig is disclosed. The method may include receiving a hole pattern having a plurality of planned holes and generating at least a first group of parallel pathways and a second group of parallel pathways between the plurality of holes of the hole pattern. The first group of pathways may be angled relative to the second group of pathways. The method may also include selecting between the first group of pathways and the second group of pathways based on which group of pathways includes fewer total pathways. The method may further include generating a combined pathway by linking at least one pathway from the selected group of pathways to at least a second pathway from the selected group of pathways and transmitting the combined pathway to a module configured to control movement of the mobile drill rig
