DevelopMent of An effectIve MethoD for ZonInG the eArth's surfAce In heteroGeneIty of the rocK MAss purpose. Development of a method for zoning the field surface according to the degree of problem by the criterion based on changes in the geoenergy of the rock mass, determined by the difference between the sum of potential gravitational energies and elastic deformations of the rock mass in the initial and current states. Methodology. The research was performed using methods of causeeffect analysis, physical modeling and geomechanics. findings. The method for zoning the field surface according to the degree of problem is developed on the basis of energy pa rameters determining the state of a heterogeneous rock mass and characterizing the general laws of manifestation and development of geomechanical processes. The method allows us to identify potentially dangerous areas on the earth's surface that are at the stage of involvement in the process of displacement, and therefore cannot be identified by ground observations and remote sensing methods. Based on the method, recommendations for optimizing geodetic monitoring have been developed. originality. A method has been developed that increases the reliability of the zoning of the earth's surface of the field according to the degree of problematicity, based on a criterion involving parameters that determine the geoenergy of the rock mass in the current and initial states. practical value. The method improves the quality of situational control, predicts the occurrence of risk situations and their development, and optimizes geodetic monitoring.
Purpose. Development of a new method of zoning the surface of the field according to the degree of rock weakness, which is based on the energy criterion, which is determined by the difference in the potential gravitational energy of the rock element be tween the states of unstable and stable equilibrium. methodology. Experimental graphical analytic methods and mathematical modeling are applied. findings. A method of zonal regionalisation of the earth's surface of the deposit according to the degree of sinkhole risk, taking into account the fracturing of rocks and the distribution of rock pressure in relation to the terrain is proposed. Verification of the results of the analysis of previously performed methods and theoretical propositions to substantiate the anisotropy of the density of the rock massif is carried out. The new method for determining the stressstrain state of a mountain massif considers the geoen ergy of its density. originality. A new method has been developed for determining the stressstrain state of a rock mass through the difference in geoenergy between the state of stable and unstable equilibrium of a mass element. Practical value. The developed method made it possible to increase the accuracy of the construction of the situational map of the field zoning according to the energy criterion by 15-20 %.
