Analyses of parabolic processes to assess mapping stability of mining area ground dislocations in the INGEO system
Journal Title: Mining – Informatics, Automation and Electrical Engineering - Year 2016, Vol 528, Issue 4
Abstract
The article features deliberations concerning the analysis of the following in the homomorphism of processes: deformations corresponding to the medium (rock mass) vibrations which generate physical threats in the subarea of topological transformations. Here, the basic issue is deformation mapping applied to model the dislocation processes related to the paraseismic process. Time dependencies are characterized by structure and dynamics of the processes. The damage of the part of the rock mass near the exploited deposit causes deformations and, most frequently, topological transformation of successive layers. Quite often rock bursts are generated, which is related mainly to the exceeded boundary states of the medium. Here it is very important to have measuring information about the medium transformations. In addition, it is necessary to define parameters and measures that characterize the anisotropy of the rock mass structures. The research within the INGEO project was focused on solutions based on the adaptation of the parabolic differential description supported by monitoring a concrete physical dislocation process. The mapping state of the process trajectory was distinguished in the deformation space by means of mathematical algorithms. Numerical modelling of deformation fields was supported by GPS sensors (innovative direct monitoring), on-line GNSS technology, and compaction sensors with a view to measuring complex dislocation fields. This solution is a new technology. A parametrically optimized model adequately illustrates a standard (measurement results) layout of vertical dislocations.
