“…Adams and Jager (1980) first observed this phenomenon using a borehole periscope at an embedded depth of 2000-3000 m in the Witwatersrand gold mine, South Africa. Shemyakin, Fisenko, and Kurlenya (1986), Shemyakin et al (1986), Shemyakin, Fisenko, and Kurlenya (1987), Shemyakin, Kurlenya, and Oparin (1989) explored zonal disintegration by using a resistivity meter in the Taimyrskii deep mine, Russia. The phenomenon has also been observed in China (Li, Qian, and Zhang, 2009).…”

Purpose: When producing mining operations in high-stress rock massive, technogenic seismicity is manifested. Forecasting and prevention of these events is given much attention in all countries with a developed mining industry. From the point of view of the paradigm of physical mesomechanics, which includes a synergetic approach to changing the state of rock massive of different material composition, this problem can be solved with the help of monitoring methods tuned to the study of hierarchical structural media. Changes in the environment, leading to short-term precursors of dynamic phenomena, are explained within the framework of hierarchical heterogeneity and nonlinearity from observations of wave fields and seismic catalog. For that purpose it is needed to develop new algorithms of modeling wave field propagation through the local objects with hierarchical structure. Design/Methodology/Approach: It had been constructed an algorithm for 3D modeling electromagnetic field for arbitrary type of source of excitation in N-layered medium with a hierarchic conductive and magnetic intrusion, located in the layer number J. It had been constructed algorithms for 2D modeling of sound diffraction and linear polarized transversal seismic wave on an anomaly elastic or dense intrusion of hierarchic structure, located in the layer number J of N-layered elastic medium. We used the method of integral and integral-differential equations for a space frequency presentation of wave field distribution. Findings: From the theory it is obvious that for such complicated medium each wave field contains its own information about the inner structure of the hierarchical inclusion. Therefore it is needed to interpret the monitoring data for each wave field apart, and not mixes the data base. Practical Value/Implications: These results will be the base for constructing new systems of monitoring observations of dynamical geological systems. Especially it is needed to prevent rock shocks in deep mines by their exploitation or natural hazards.

“…After the discovery of zonal disintegration phenomenon near deep level tunnels by Russian scientists in seventy-eighty years in the last century [1] a lot of experimental and theoretical investigations, for example [2][3][4][5][6][7][8], have been performed. Experimental and theoretical studies have also been carried out in China [9][10][11][12][13][14].…”

In the present paper zonal disintegration phenomenon is investigated within the framework of gradient theories of elastic-plastic solids. Gradient of effective plastic strain is introduced as additional internal variable. Equilibrium equation and boundary conditions are obtained by using virtual work principle. Evolution equations for internal variables are obtained by using Clausius-Duhem inequality. For circular tunnels the governing equation for effective plastic strain is obtained from the above model. Solution of the governing equation for ideal brittle rock mass model is obtained. The obtained solution may describe zonal disintegration phenomenon very well.
