Abstract
An object of the invention of the present application is to provide a mine management system capable of accurately maintaining and managing the productivity of a mine. To achieve the object, a processing device is configured to generate mesh information of travel cycles in which mine vehicles move from a location in which earth is dumped to a location where the mine vehicles are loaded with a load and then move again to the earth removing location, on the basis of positional information of the mine vehicles, compare the mesh information of the travel cycles with mesh information of routes stored in a storage device to classify the travel cycles to any one of the routes, compute productivity indexes of the travel cycles on the basis of working information of the mine vehicles, compare the productivity indexes of the travel cycles with a productivity reference value of the one of the routes to detect a productivity decline of the one of the routes, and output the detected productivity decline to a display terminal device.
