Rock mechanics aspects of sequential grid mining

A project report submitted to the Faculty of Engineering,
University, of the Witwatersrand, Johannesburg, in partial
fulfilment of the requirements for the degree of Master of
Science in Engineering
Johannesburg, 1991 / As mining proceeds deeper on Elandsrand Gold Mine scattered mining will no longer be viable due to the excessive stress levels which would occur during mining of the final remnants between raises. Longwall mining with strike stabilizing pillars would eliminate this need for remnant mining. However, since the Ventersdorp contact Reef on Elandsrand has a relatively large number of faults and dykes and highly variable grade, longwall mining would result in a excessive amount of off-reef mining and mining of unpayable reef. / GR 2017
