| 发明名称 | Method and apparatus for detection of drill bit wear | ||
| 摘要 | 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. | ||

| 主权项 | 1. A method for determining wear of a drill bit, comprising: drilling a first hole in a worksite based on a hole pattern having a plurality of planned holes; determining an energy required to drill the first hole; drilling a second hole in the worksite; determining an energy required to drill the second hole; 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; and determining strata through which the drill bit is passing during drilling the first hole and drilling the second hole. | ||
