Title

Support of Underground Excavations in Deep-Level, Hard-Rock Mines - 1. Thin Tabular Stopes

Abstract

A summary of the traditional mining methods and support techniques normally used in the South African mining industry and a detailed review of the support types used in these mines are given. To obtain a clearer understanding of mine support behavior laboratory tests were conducted with various pack constructions built from timber, concrete and other materials. These tests were performed with a special-purpose rigid hydraulic press developed specifically to simulate underground conditions. The laboratory investigations highlighted the advantages that accrue from a composite pack support constructed from concrete blocks and timber slabs incorporated within the same layer. Underground field trials with composite packs in a stope 4500 ft below surface resulted in improved strata control and a better control of the stoping width.
