Open Pit Mine Blasting When it comes to openpit mining the most visually appealing aspect is the blast. It''s loud, intense, and who doesn''t like a good explosion once in a while. This video showcases a compilation of blast videos taken at a variety of openpit mining sites in Canada. Prepare to be blown away. Blasting PowerPoint Presentations
Maximising coal recovery in challenging geology and extracting marginal seams represents a significant opportunity for most coal mines to increase the value of their resource. As the easy coal is mined out, mine operators need to become more skillful at mining thin, steep, deep and undulating seams productively and without sacing coal quality.
