Vehicles and other objects in a surface mine are equipped with monitoring devices (1, 2, 3) that derive own and foreign positions ( P_1, P_2, P_3) and/or mutual distances (d_12, d_23, d_13) using time-of-flight measurements of radio pulses and/or using GNSS-receivers (20). Thus, the vehicle or object operator can be warned if the risk for a collision or dangerous approach is detected. |
