FEATURES OF RISK DETERMINATION AND CONTROL OF THE UNDERGROUND FACILITIES STABILITY LOSS UNDER CONDITIONS OF ROCKS PROPERTIES VARIATION

Abstract

Problem statement. Modern geotechnical production or an underground structure used as a military-industrial facility must meet the requirements of international risk management standards, which form the basis of safe and effective management. Implementation of effective risk management improves the quality of decision making, and has a positive impact on the benefit of the enterprises and society as a whole. The purpose of the article. To improve the method of risks’ determining for the mining stability loss and other underground structures, taking into acount the variability of the physical and mechanical properties of rocks. Methods. The use of a systematic approach in analytical studies of literary sources, systematization of modern approaches and methods in determining risks in the life safety system, processing by statistical methods, and the use of probability theory. Research results. Based on the results of field studies of the underground mining of the Yubileynaya mine at the Pershotravenskoye Mining Structural Division of PuAT DTEK Pavlogradugol, graphs of roof deformations were constructed, displacements were determined, dependencies were obtained, and the risks of underground mining destruction were identified. Scientific novelty. For the first time, the use of the parameters’ scatter by their standard deviation in identifying the risk of stability loss for underground mining is proposed. Practical value. A methodology for identifying and predicting geomechanical parameters for a risk-oriented system for monitoring the stability of the rock mass while ensuring safety when using developments as military-industrial complexes is proposed.
