“…It is interesting that by DTA data (see Fig. 8), volatile removal in some specimens is accompanied by endo-effects at a temperature somewhat higher than 2 T . This may be the consequence of volatile desorption.…”

“…Such knowledge, considering features of geomechanical processes at various specific, intrinsically multiple-phase mineral deposits must be the basis for reliable geomechanical-geodynamic safety systems for mines operating in highly hazardous conditions [2,3]. This knowledge, in a way, ensures an invariant procedural core in projecting universal geomechanical monitoring systems for various mineral deposits.…”

The paper presents laboratory and in situ research data on interaction of geomechanical and physicochemical processes in Kuzbass coal of various ranks, considering temperature effect. Under analysis is the relation of stress-strain state, temperature and infrared radiation of coal. The authors study the role of temperature and microstructure of coal in energy and mass exchange processes (variation of mass, volatile yield, specific surface, internal energy of methane adsorption capacity decrease and moisture content).Interrelation of outburst hazard and fire hazard in coal is discussed from the viewpoint of uniform stagewise thermomechanics and thermochemistry of coal behavior in the course of coal formation and extraction.The article introduces a generalized factor for quantitative description of petrographic properties of coal.Using this factor, the authors classify and describe petrographic groups of Kuzbass coal.

“…For example, by surveying service data in Norilsk mines, typical depths of rock falls from drive walls mostly range from 0.5 to 2.0-2.5 m and sometimes are 3-4 and 8 m (usually, in the roof). Assuming the rock fall depth as a linear size of a geoblock, it is possible to estimate fracture "opening" using (1). For the mentioned depths (geoblock sizes), the "openings" will range from 2.5 mm at 5 , considering that fracture depth is seldom above 4 m, fracture opening may be 2.5 to 40 mm.…”

“…This article's Part I focused on experimental validation of alternating response of rocks to different power blasting and described primary mechanical and mathematical models to represent this phenomenon [1]. The discovery of alternating response of rocks to dynamic impact dates back to the 1970-80s, aided by geophysical and geodetic downhole methods, which made it difficult to follow comprehensively, in space and time, transition of rocks from "original" mechanical state to "limit" state after blasting.…”

The article reviews research and development results in the sphere of designing unique apparatuses and equipment for modeling and in situ recording of nonlinear elastic waves and associated electro-magnetic emission in block-hierarchical rock masses in the condition of high stresses. The joint experimental outcomes and theoretical research findings gained by leading institutions of the Russian Academy of Sciences and its branches within recent decades, in the framework of integration interdisciplinary projects offer the methodology and instrumentation support for new promising systems of integrated geomechanical and geophysical monitoring of mining-induced earthquakes and rockbursts in Russian mines that may act as unique natural "laboratories" for both academic and applied research in geosciences.
