A collision detection and avoidance system for a mine, comprising means configured for performing: - receiving mine operations data from a set of data sources (1110, 1111, 1112, 1113, 1114) in the mine, the mine operations data comprising collision detection and avoidance data related to mining vehicles (4, 5, 6, 7), - processing the mine operations data to detect a set of collision detection and avoidance events (60, 61) meeting at least one operator attention triggering condition, - mapping the set of collision detection and avoidance events (60, 61) to a mine model on the basis of location information associated with the collision detection and avoidance events (60, 61) in the set of collision detection and avoidance events, - determining an affected location area of the set of collision detection and avoidance events (60, 61) mapped to the mine model, the affected location area of the set being defined on the basis of predetermined radius around each collision detection and avoidance event (60, 61) in the set of collision detection and avoidance events, wherein a size of the affected location area depends on criticality of the collision detection and avoidance events, - generating, on the basis of the set of collision detection and avoidance events (60, 61) and the affected location area, an operator attention indicator dependent on density of collision detection and avoidance events in the affected location area, - controlling coloring in the affected location area on the basis of density of the set of data events; and - controlling display of the operator attention indicator for the set of collision detection and avoidance events in the affected location area in the mine model to an operator to adjust operation of one or more mine operations devices. - receiving mine operations data from a set of data sources (1110, 1111, 1112, 1113, 1114) in the mine, the mine operations data comprising collision detection and avoidance data related to mining vehicles (4, 5, 6, 7), - processing the mine operations data to detect a set of collision detection and avoidance events (60, 61) meeting at least one operator attention triggering condition, - mapping the set of collision detection and avoidance events (60, 61) to a mine model on the basis of location information associated with the collision detection and avoidance events (60, 61) in the set of collision detection and avoidance events, - determining an affected location area of the set of collision detection and avoidance events (60, 61) mapped to the mine model, the affected location area of the set being defined on the basis of predetermined radius around each collision detection and avoidance event (60, 61) in the set of collision detection and avoidance events, wherein a size of the affected location area depends on criticality of the collision detection and avoidance events, - generating, on the basis of the set of collision detection and avoidance events (60, 61) and the affected location area, an operator attention indicator dependent on density of collision detection and avoidance events in the affected location area, - controlling coloring in the affected location area on the basis of density of the set of data events; and - controlling display of the operator attention indicator for the set of collision detection and avoidance events in the affected location area in the mine model to an operator to adjust operation of one or more mine operations devices.
