Geodetic Determining of Stockpile Volume of Mineral Excavated in Open Pit Mine

Abstract

In the contemporary geodetic practice it is practically a must to use modern geodetic apparatuses and a variety of the cad (computer aided design) software for processing and visualising spatial data. The present paper deals with geodetic surveying of kecerovce open pit mine to determine, for the purpose of mine reopening and commencing with mining of andesite, the volume of non-extracted volumes of andesite. The open pit mine is situated on the foot of slanské vrchy mountain range. Determining of the auxiliary survey control points and the quarry vicinity was performed by gnss technology and rtk method. Detailed surveying of the open pit mine was performed through an electronic total station. by measurements attained spatial data were processed by pertinent proprietary software. Subsequently, the determined spatial coordinated were imported into the graphic-calculating softwares for further processing and visualisation. These graphical-calculating applications make possible not only 3d modelling and visualising of surfaces but also their analysing, especially then determining the volumetric data that represent various aspects necessary to assess as activities within the related branches so possible future development.
