CHOICE OF ROCK PRESSURE CONTROL METHODS DURING DEVELOPMENT OF DEEP DEPOSITS

Abstract

Mining is a sphere of human activity associated with the extraction of minerals from the subsoil under the conditions of a sign-alternating change in the stress strain state (SSS) of the rock mass. A change of the SSS can manifest in sudden destruction of mountain structures, as well as through earthquakes.
Prediction of the place and time of manifestation of rock pressure is currently one of the most urgent tasks. The annual growth in the use of preventive measures with a practically unchanged number of dynamic manifestations of rock pressure and an increase in the relative number of rock bursts indicates the low efficiency of traditional rock burst prevention measures, which necessitates the development of new methods for predicting and preventing rock bursts.
Using the results and measurements in the accessible to us 11-year cycle of solar activity, we revealed the regularities in the occurrence of deformation, as well as of stresses in the rock mass. There was a rationale for changing the physical state of measuring instruments based on electromagnetic waves: satellite navigation systems, light and radio rangefinders.
At the same time, we found that all these parameters change continuously and infinitely over time, and they will need the monitoring in order to give a reliable forecast of their impact on the technogenic activity of mining enterprises.
Rich experimental material about the relative deformation of matter, and most importantly about the deformation of the rock mass, i.e. of the earth's crust, obtained over many years of research, made it possible to find a way out to solve this problem using the very behavior of the rock mass in response to technogenic activity.
