ИССЛЕДОВАНИЕ КОРОТКОПЕРИОДНОЙ ГЕОДИНАМИКИ МАССИВА ГОРНЫХ ПОРОД КАЧКАНАРСКОГО ГОРНО-ОБОГАТИТЕЛЬНОГО КОМБИНАТА

Abstract

This paper presents the methodology and results of the study of modern short-period geodynamics of the activity of the rock mass of the Kachkanar mining and processing plant (MPP). The determination of the parameters of geodynamic movements is carried out in the form of continuous monitoring by satellite geodesy complexes over a point system for several hours or days. The need to conduct studies on the organization of geodynamic monitoring in the quarries of the Kachkanarsky MPP is due to the peculiarities of the tectonic structure of the enclosing massif, in particular, the influence of a series of active tectonic disturbances crossing the quarries and tailings. The manifestations of geo-dynamic activity, which is realized in the form of trend and cyclical short-period shifts in tectonic disturbances, are associated with deformation processes occurring on the north-western side of the Main Quarry, as well as a breakthrough of the tailings dam. The role of cyclic geodynamic movements in the formation of the general stress-strain state of the area where quarries and tailings are located is shown. At the same time, these geodynamic movements lead to the formation of fatigue effects in structures and materials, “loosening” of the massif of rocks composing the instrument massif, a change in the strength properties of soils at the base of engineering structures, and the manifestation of the thixotropy effect.
