抄録

Recently the variation in stress in rocks has come to be measured, for the purpose of earth pressure control, using several kinds of stress meters or strain meters. The relationship among the measured value, the variation in stress and the present state of stress are complicated. Thus the authors have analyzed this relationship and have presented fundamental data for the interpretation and utilizatio n of the results of measurement.<BR>Some of the results of stress measurement which have been carried out at some metal mines working massive ore bodies are introduced. It has been found from these measurements that the measurement of the variations in stress in pillars or rocks gives a useful data for earth pressure control, However, it is not yet possible to predict cavings merely from the results of measurement.
