|A review of the current pit design procedures and their performance has been undertaken recently by Mining Research Associates (MRA) and the CSIRO Division of Geomechanics. Visits were made to mines covering a wide range of operations. A questionnaire was completed by each mine in order to collate the relevant information. Interviews were also made with representatives of the Mines Departments to ascertain their role in regulating mine designs. Design expectations were compared with field performance, and reasons for variations noted. Problems associated with designs were identified and suggested methods of alleviating the problems have been made.|
