Determination of stress concentrations around mine workings affected by stoping operations
Authors:
Abstract
Preparatory mine workings are usually subjected to the action of support pressure caused by stoping operations. For solving a number of practical problems, a qualitative and quantitative assessment of this effect on the stress state of rocks near them is of great importance. For the first time, the effect of a stoping face on the stress distribution in the vicinity of a working of square shape with a smooth contour was studied by A. S. Kosmodamiansky. In practice, however, they occur in various shapes with smooth and irregular contours.
