STUDY OF THE ROCK MASS FRACTURE BASED ON DATA ON SEISMICITY AND STRESS-STRAIN STATE
Abstract
In the paper the authors present the study results of rock massif fracture based on the case study of a rockburst hazardous Khibiny deposit. The authors have revealed peculiarities in seismic process at different mining stages over a five-year period. The principal aim was to study the particularities of seismicity occurrence when the deposit is mined by approaching fronts, namely, in the periods between bulk blasts in the docking sections between them. The authors have proposed an approach to reveal the features of the seismic process based on a multistage model of solids’ failure and a modified concentration criterion, which takes into account the time factor when identifying seismic events’ clusters formed under the influence of various natural and mining-induced factors. Such an approach makes it possible to account the spatial and temporal characteristics of seismicity and to determine the peculiarities of interaction between different scale events: - Varying the critical values for combining seismic events into a cluster allows revealing the features of the seismic process progress; - Using the time factor allows studying in detail the peculiarities of seismicity occurrence, taking into account various influencing factors; - Excluding single events from study allows simplifying the task of investigating a complicated seismic process during mining operations. The paper presents estimation results of a specific energy magnitude within the entire study area of the deposit. During the whole research period there is a decrease in the specific energy of the rock mass deformation in the studied area. This approach makes it possible to study the features of energy exchange in the rock mass based on released seismic energy data and data on the stresses redistribution.
