THE APPLICATION OF TERRESTRIAL LASER SCANNING FOR THE MANAGEMENT OF MINING IN REAL TIME
Abstract
In the opencast coal mining we face the excavation, transport and the storage of a substantial volume of materials. One of the main and regular tasks for surface mines are therefore the calculations of volumes and the monitoring the progress of extraction. The main objective of the measurement is to determine the geographic position of bucket-wheel excavators and lay down their basic geometric parameters, which define their position within three-dimensional space. This way we can monitor, plan and manage mining processes better on stripping areas in coal mining sections. Thus, we can minimize the risk of soil landslides on an excavator and avoid collision with drilling equipment and the underground mine workings. The geometric parameters of bucket-wheel excavators obtained using 3D laser scanning is one of the important parts of the whole process, which enables the management of mining in real time. The application of laser scanning techniques to bucket-wheel excavator surveying seeks primarily to determine the machines? key geometric parameters and to stablish mathematical models of their movement dynamics in 3D space. The measurement is taken at the site of Doly N?stup Tu?imice Mines (DNT), which come under the company Severo?esk? doly a.s., the largest producer of coal in the Czech Republic.
