CONTROL OF THE MOUNTAINOUS AREA STRESS-STRAINED STATE BY THE SOUND RANGING AND GEOPHYSICAL METHODS

Abstract

The level of industrial safety in the mining branch remains one of the low, which is caused, in the first place, by the insufficient mastery of the geotectonic conditions for section, by the absence of innovation developments in warning of extraordinary situations with the mine-constructing and mining works, by the weak automation of the dangerous operations of production process. However, the main reason for high accident rate in the mountain branch is the low level of the of the manifestation and development control organization in the massif of deformation processes, the insufficient resolution of the utilized methods of control, complexity and high costs of conducting observations, lack of interference defense of the utilized radio circuits and power lines of measuring units. Work examines the basic sound ranging and geophysical methods of the stress-strained state dynamics of the rocks checking, physicomechanical changes in the matrix of the rock at the level of structural-textural packing and crystal lattice. The effectiveness substantiation of the fiber-optic materials use as the communications lines and detectors of pressure on the basis of the Bragg diffraction lattice is given.
