Geotechnical Design for Sublevel Open Stoping

first_imgThis volume from CRC Press is published next month. It is the first comprehensive work on one of the most important underground mining methods worldwide, presenting topics according to the conventional sublevel stoping process used by most mining houses, in which a sublevel stoping geometry is chosen for a particular mining method, equipment availability, and work force experience. Summarising state-of-the-art practices encountered during his 25+ years of experience at industry-leading underground mines, the author, Ernesto Villaescusa of the Western Australian School of Mines:•Covers the design and operation of sublevel open stoping, including variants such as bench stoping•Discusses increases in sublevel spacing due to advances in the drilling of longer and accurate production holes, as well as advances in explosive types, charges, and initiation systems•Considers improvements in slot rising through vertical crater retreat, inverse drop rise, and raise boring•Devotes a chapter to rock mass characterization, since increases in sublevel spacing have meant that larger, unsupported stope walls must stand without collapsing•Describes methodologies to design optimum open spans and pillars, rock reinforcement of development access and stope walls, and fill masses to support the resulting stope voids•Reviews the sequencing of stoping blocks to minimize in situ stress concentrations•Examines dilution control action plans and techniques to back-analyse and optimise stope wall performanceFeaturing numerous case studies from the world-renowned Mount Isa Mines and examples from underground mines in Western Australia, Geotechnical Design for Sublevel Open Stoping is both a practical reference for industry and a specialised textbook for advanced undergraduate and postgraduate mining studies.CRC Press Content:541 Pages | 431 Illustrations.
