Abstract

Email to a Friend
A lead-zinc orebody, in fairly strong quartzite and with a dip of 35° to 60°, is block-caved by use of scrams in a stair-step pattern up the ore footwall. Scram linings to handle coarse muck and permit the use of folding scrapers are developed by the use of end-grain wooden blocks to reduce maintenance and keep operating cost to a minimum.
