This report describes a method for determining the stress in rock based on a requirement for static equilibrium; namely, that the total load on a sufficiently large area must remain constant even after a drift or stope is mined in the area. The method is based on mathematical relationships that are independent of the elastic properties of the rock and the stress distribution near the underground opening. In addition to determining the pre-existing stress (before mining), the method described can be used to determine the change in stress due to mining. /Author/
