Processing, analysis and interpretation of blasthole drilling data— Peculiarities and problems

The article discusses application of the Measurement While Drilling technology (MWD) in mining and blasting. The global analysis of Russian and foreign projects and paperwork allowed identifying the lines of the further research connected with application of this technology in drilling-and-blasting in mines. The relevant basic research works are reviewed, the current situation is described, and the way of improving the technology for drilling machines and assemblies is shown. The approaches and problems connected with drilling monitoring, revealed during the drilling data accumulation and analysis, are comprehensively described. The analysis exposed the chief bugbears to be specially treated in introduction of the MWD systems, and pointed at the common difficulties connected with the blanket implementation of the technology at a commercial scale in the mining industry. Based on the accomplished review and analysis of the global Russian and foreign MWD projects, a summary on the existing approaches to data evaluation and verification to overcome difficulties and uncertainties connected with global application of the MWD technology in the mining and construction industries is presented, and the key points to be additionally investigated and verified because of the data inconsistency are highlighted. The major research trends worthy of attention and interest of scientists engaged in development of this research issue are defined.
