Rocks mineable by the opencast method represent mostly hard rock masses which need preliminary shattering by blasting. In the space-limited environment of lower benches in open pits, the problem connected with rock fragmentation quality aggravates. This weakens performance of modern truck-and-shovel systems and raises the standards of geomechanical support of mining operations. At the same time, finding a new and unused potential of enhancing drilling-and-blasting efficiency is impossible without reliable and prompt informational support. The outcome of blasting is affected by the tight timing of massive blast design engineering which is carried out concurrently with mining. It is proposed to ensure early reporting of reliable source data using special hardware/software systems. For the adjustment of actual rock mass zoning by blastability, the lack of which leads to increased power factor and higher explosive consumption, it is suggested to install intelligent hardware/software systems on drilling rigs and shovels. Furthermore, for obtaining authentic and up-to-date information, the topographic surveying using unmanned aerial vehicles and a special technology of data processing within a block is proposed. This technology simplifies survey data interpretation and improves blasting accuracy.
