Abstract

A management system of the mining machine includes a position information detector which detects position information about the mining machine; an operation information detector detecting operation information about the mining machine; and a first evaluation device evaluating the operation information based on the position information and the operation information. A route in a mine includes nodes disposed at a predetermined distance and links connecting between the adjacent nodes, and includes route information including a specific section in which a difference in a gradient between the adjacent links is a predetermined value or less, a difference in an orientation between the adjacent links is a predetermined value or less, and no intersection exists between the adjacent links. The first evaluation device evaluates the operation information in the specific section of the route.
