Concepts of 3D terrain modeling and geomorphometric analysis in mining

Abstract

This paper describes the concepts of 3D terrain models and their application in mining. The methods of terrain (relief) by spots elevation and contour lines are commonly applied on geodetic plans and topographic maps. Appearance of the technologies has changed the way of modeling and analysis of geospatial data, i.e., applying the concept of digital terrain models (DTM). This approach emphasizes the importance of geomorphometric analyses and monitoring changes on the field in time. Application of 3D geodata models in digital format (raster or vector) becomes increasingly used in mining. Therefore, it is important to describe the concepts and features of 3D geodata models and potential applications and monitoring changes in the field in time and space.

Software solution for the mine subsidence prediction based on the stochastic method integrated with the GIS

“…Integrative modeling, interac tive spatial analysis and understanding different processes are supported by the GIS. Based on the simulation of spatially distributed and time-dependent subsidence processes, innovative thematic maps containing the land-surface properties can be designed [7][8][9][10][11].…”

“…GIS is used for creatinh complex geodatabase, converting numerical data, imported from the SUBSIDENCE and DEFOR-MATIONS modules, in feature classes and graphical data as well as for performing the spatial analyses of subsidence and deformations [7][8][9][10][11]. Since the pit consists of multiple panels with complex geometry, spatial analyses requires a long time without GIS because for each panel subsidence or deformations must be presented cumulatively.…”

Vertical accuracy of data on the topographic maps and their application in mining

“…Data on the relief and land forms of the TM25, TM50 and TM100 are given in Table 5. When it comes to show the land forms, the nature of that element of content the topographic maps should be the least changeable, (Petrović, at al., 2016). However, in the relief area there is a variety of changes due to the human activities (reclamation, mining, etc.)…”
