Publ Montreal: CIMM, 1978 Discusses the type of fill used for each mining method employed (e.g. sublevel open stoping, cut and fill, pillar extraction by caving Qr massblasting). Types of fill include uncemented rockfill and c~nented hydraulic fill. Research into fill properties, iucludir4~ the development of finite element programs for stability analysis, is surmmarised. 802128 FILLING PRACTICES AT BRUNSWICK MINING - NO 12 MINE Gignac, L Proc 12th Canadian Rock Mechanics Symposium, Sudbury, Ontario, 23-25 May 1978, P30-36. Publ Montreal: CI~, 1978 Describes the use of crushed rock fill and compares the properties of this material with railings fill. Rock reinforcement by grouted rebars is preferred to densification of the backfill. 802129 EVOLUTION OF FILL MINING AT THE ONTARIO DIVISION OF INCO METALS Bar sotti, C Proc 12th Canadian Rock Mechanics Symposium, Sudbury, Ontario, 23-25 May 1978, P37-41.

Publ Montreal: CIMM, 1978 The stability of exposed vertical walls of cemented fill is considered by performing twoand three-dimensional finite element analyses. It appears that the most efficient use of fill is one that promotes arching and that stability depends on the minlm~m dimensions of the filled stope. 802136 MODELLING TO PREDICT BACKFILL STABILITY IN TRANSVERSE PILLAR EXTRACTION Cundall, P; Shillabeer I J H; Hergetj G Proc 12th Canadian Rock Mechanics symposi~n, Sudbury, Ontario, 23-25 May 1978 , P02-99. Publ Montreal: CIMM, 1978 Repcrts the development of an interactive computer model which uses a three-di~nsional, explicit I Largrangian finite difference code limited to rectangular geometry and small strains. Results are given of hypothetical trials in which the model predicted the responses of rock and backfill through successive stages of stoping, filling and pillar extraction. Failure mechanisms were predicted. 8O2137 BACKFILL RESEARCH FOR PILL#/~ Ek~RACTION AT ZC,/ b~HC Askew, J; McCarthy, P L; Fitzgeraldj D J Proc 12th Canadian Rock Mechanics symposium s Sudbury3 Ontario, 23-25 May 1978 , PlO0-1]O.
