MODELING OF THE SYSTEM "MINE WORKINGS – SUPPORT – INTEGRATING ROCKS" WITH THE SOFTWARE VISUALIZATION ENVIRONMENT

Abstract

The paper describes the construction of a computer 3D
model based on heterogeneous initial data. This system
model includes a vertical mine working which comprises
in a shaft of the “10th anniversary of Kazakhstan's independence mine”, a support with a set of damaged areas and adjacent rocks. This model is built in the Mineframe software environment and consists of following submodels: geological submodel, mineshaft’s submodel and damage submodel. The geological submodel contains
boundaries of the selected engineering geological elements and data related to detailed geological layers within these elements (petrographic composition, the Protodyakonov coefficient, rock fracturing). In addition, it contains solid and block models of the contour massif sections surveyed with ground-penetrating radar. The mineshaft’s submodel contains a wireframe and a solid model of the mine working. The damage submodel is built on the basis of shaft survey data, it contains wireframe and solid models of detected faults to the shaft lining (water jets outflows, damage to the waterproofing and divergences of construction joints, cutter break and cracks zones in concrete, a single attachment violation of the bunton and leak at an attachment point of the bunton). Building of vertical and arbitrary sections is possible on the basis of the described model with using symbols created with built-in Mineframe toolkits (classifier, line and hatch, symbol, palette editors). In a work process, the volumes of target breeds are calculated. The model can be used for a complex analysis of the total data from ground-penetrating radar sensing and visual inspection of the shaft, as well as for improving of efficiency assessment of the planned wellbore operations in this mineshaft.
