Convergence measurement of CSM Sever vent shaft and adjacent surroundings on 3rd floor using 3D terrestrial laser scaner technology

Abstract

On the basis of a contract, the Institute of Geonics of the CAS realized repeated convergence measurement of selected part of the mining roads and appropriate part of vent shaft on the 3rd floor in the vicinity of the CSM Sever vent shaft. The main reason was to capture spatio-temporal and dynamic changes in relation to the mining of the coalface No. 292 200/4. A section of the embankment of the 3rd floor of the vent shaft was selected for the convergence measurement.\nThe subject of the use of terrestrial laser scanning technology was to capture the current spatial situation of the vent pit on the 3rd floor of the CSM Sever mine and its adjacent surroundings. The wider area around the shaft and the part of the vent shaft directly visible from the level of the galleries of the 3rd floor were scanned. The scanning was performed using a Leica ScanStation C10 laser scanner. The rescanning was performed using a FARO Focus S350 laser scanner
