TO THE PROBLEM OF DEVELOPING NEW METHODS FOR ESTIMATING THE MECHANISM OF FORMATION OF FOCAL ZONES OF CATASTROPHIC EVENTS IN CARBON BEDS

Abstract

The article shows that the problem of safe mining is largely related to ideas about the mechanisms of interaction of nonlinear geomechanical and physicochemical mass-gas exchange processes in multiphase coal-rock massifs. For the first time, a complex of generalizing analytical, experimental laboratory and field studies at the regional level, carried out by the authors, made it possible to establish that in modern conditions, with the development of deep horizons, the role of rock pressure, temperature and geostructural factors, as well as the presence of an increasing influence of the seismic background from earthquakes and technological explosions. A numerical simulation method and an original experimental system for determining the regularity of the decay of this two-phase flow were developed by Chinese and Russian specialists taking into account the influence of the gas expansion energy on the propagation characteristics of a mixture of pulverized coal and gas. The analytical basis for describing the established deterministic relationships between the existing nonlinear geomechanical and physicochemical processes in stressed coal-bearing massifs was the establishment of an operator correspondence between the physicochemical equation of I. Langmuir and the kinematic equation of V.N. Oparin for pendulum waves.
