DEVELOPMENT OF MEASURES TO ENSURE THE STABILITY OF A ROCK MASSIF WITH THE USE OF MODERN SURVEYING INSTRUMENTS

Abstract

in the development of a mineral deposit by an underground method with the collapse of the overlying strata of the rock mass, failures and collapse zones form on the earth's surface. Dips and collapse zones on the earth's surface are used as a disturbing factor that cause a redistribution of stresses in the rock mass. The resulting cavities filled with collapsed rocks can be approximated on the earth's surface by a circle or an ellipse. A technique and schemes are proposed for calculating stresses when a collapse zone reaches the earth's surface in the form of a circle, using the results of observations of the displacement of benchmarks on the earth's surface along profile lines.
