Engineering Tools for Design, Analysis and Information Management Applied to Underground Drilling and Blasting

In underground mining, the often unpredictable variability in ground conditions may lead to the application of suboptimal drilling and blasting patterns, resulting in poor performance. Experience and pertinent information to develop and implement improved drilling and blasting strategies can be easily lost due to the lack of means to help engineers store, access and manage this information. The Julius Kruttschnitt Mineral Research Centre (JKMRC) through a series of industry funded applied research projects has been developing a system that can facilitate the drill and blast design, analysis, auditing, documentation and data management processes. The system is a hybrid between an information management software module called BMS (Blast Management System) and two design and analysis modules, 2DRing for underground production blasting activities and 2DFace for development blasting activities. A concise description of the software tools and its applications are given in this paper, supported by two case studies. Opportunities to further develop the software are also highlighted, they include options to integrate these tools to existing drilling and blasting automation systems and portable computing technology to facilitate the design, implementation and continuous improvement processes.
