Applications of the artificially supported stoping method with cemented rockfill in mining

The article gives an applications of the artificially supported stoping method with cemented rockfill. Cemented rockfill is mainly used in mining thin, steeply dipping ore bodies. A study of cemented rockfill application has shown, that the average strength of fill mass ranges from 2 to 5 MPa; the size of coarse aggregate plays an important role and it is recommended to use sizes within the range from 70 to 100 mm; the most common binder is Portland cement; mine and groundwater are suitable for mixing provided that 4 ≥ (pH) ≥ 12.5, sulphate content does not exceed 2.7 g/l, and that of other solids is less than — 0.3 g/l maximum. The article gives recommendations for further research in the field of cemented rockfill, application in particular: the determination of its strength properties at coarse aggregate sizes from 150 to 200 mm; determination of design parameters of the mining system; numerical modelling of stress-strain changes in rock mass during mining, development of recommendations on the use of the cemented rockfill based on the results of pilot tests. In order to reduce the cost of mining with cemented rockfill, the following order of operations is recommended: first, cemented rockfill pillars are formed, then the stope reserves are worked out, and then the stope is filled with rockfill.

Keywords: ore deposits, thin ore bodies, steep ore bodies, room-and-pillar method, cemented rockfill, rockfill, rib pillar, unconfined compressive strength of cemented rockfill.
