Improving microseismic monitoring efficiency and accuracy at a mine requires an integrated effort. This article discusses a case study which demonstrates that the monitoring efficiency and accuracy can be drastically improved through optimally using the existing array, efficient techniques for signal processing and noise separation, and the advanced location algorithm which not only offers a robust search scheme, but also features the techniques for efficient data utilization and further error detection and minimization. The study is a collaborated research between Penn State and NIOSH researchers for the better use of microseismic technique for mine safety, ground control and roof fall prediction.
State-of-the-art software and computer technology provides a vehicle for a new approach to designing and verification of blasting patterns and training of professionals in this area of mining. The objective of this paper is to discuss the use of 3-D computer graphics to improve the understanding of the challenges facing drill and blast operations and describe technologies available for drill and blast planning in surface mining. It is postulated that this approach will have a positive impact on future students, researchers, and mine operators by improving their ability to use techniques, skills, and visually rich tools in solving and documenting mining engineering problems.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
