Abstract: The application relates to a charging system for charging at least one charging hole. The system comprises a charging boom, sensors of the boom, a movement mechanism of the boom, a charging head of the boom for charging the at least one hole, and a controller for controlling the boom. The sensors obtain location information relating to the boom. The controller defines locations of the charging head in a co-ordinate system of the boom on the grounds of at least the obtained location information. The controller also operates the movement mechanism to move the charging head between the defined locations in accordance with precalculated movements.
