Abstract: This research proposes a novel method of recording the features of mine mills digitally by 3D laser scanner and its application. This method enables to obtain their shape features in short time independent of the expert's drawing skill. It also enables to evaluate the shape feature values, such as the position of the center of gravity, based on the obtained 3D digital data. In addition it may be possible to get a clue to clarify the process of varying the shape of mine mills. The mine mills described in this paper are remains discovered in the mountains of Yu-no-oku gold mine locating in Minami Kuma County in Yamanashi prefecture, Japan.
