Digitalization in Open-Pit Mining: A New Approach in Monitoring and Control of Rock Fragmentation

Mining enterprises are widely introducing digital technologies and automation is one of such tools. Granularity monitoring, namely, the size determination of rock mass pieces is a common operational component of the processes that extract minerals by open-pit mining. The article proposes an approach...
