A measurement systemmeasures a grade of an excavated material generated from an underground tunnel including a plurality of mining points. The underground tunnel is constructed based on a mining plan of a mine planned based on primary grade data and primary position data corresponding to the primary grade data measured in a preliminary geological survey. The measurement system includes a measuring unit (grade measuring unit)that measures the grade of the excavated material generated from the underground tunnel, a secondary grade data acquisition unit (grade data acquisition unit)that acquires secondary grade data indicating the grade of the excavated material from the measuring unit, and a secondary position data acquisition unit (position data acquisition unit)that acquires secondary position data corresponding to the secondary grade data.
