For the purpose of contributing to the design of shaft linings, especially of coal mines, the authors have attempted to measure the stress in the shaft linings in several coal mines in Japan with the photoelastic apparatus contrived by them.The results show that the lining in a solid ground is generally subjected to but a low stress, but sometimes to a stress about 30kg/cm2, that in a crushed ground the lining is subjected to a medium or high stress fluctuating, and that in a loose ground there appears such an earth pressure acting on the outer surface of the lining that may be estimated by the formula of the soil pressure.
