Optimization of the location of observation network points in open-pit mining’s

Abstract

The article discusses the use of “Open Source” software Quantum GIS (QGIS) to search for the optimal location of observation network points in open-pit mines. The exploitation time of open-pit mines is ranges from a few to several years. Interference in the geological structure causes significant degradation of the surrounding terrain. Monitoring the risks associated with the mining areas requires a properly designed measurement networks. The network geometry should ensure its stability, accuracy and the ability to study changes in the excavation even after its closure. The network design is a compromise solution that takes into account the accuracy requirements and off-road capabilities. Point location optimization supports software for spatial analysis. The purpose of the software is to use raster and vector queries in a specific scope. Data in the form of Digital Terrain Model and existing public databases allow efficient selection of a network location for large mining areas. Conducting the analysis requires current data of the studied area. Currently, a standard data collection tool is GNSS technology and Unmanned Aircraft Systems UAS. Current data and GIS software can be gradually used in Poland for open-pit mines require monitoring.
