Geotechnical Design for Sublevel Open Stoping

Book excerpt: Presenting topics according to the conventional process used by most mining houses, this book covers the design and operation of sublevel open stoping. Summarizing state-of-the-art practices encountered during his 25+ years of experience, the author discusses increases in sublevel spacing, improvements in slot rising, and rock mass characterization, as well as methodologies to design open spans and pillars, rock reinforcement, and fill masses. He also addresses in situ stress concentration minimization, dilution control action plans, and techniques to back-analyze and optimize stope wall performance.
