Abstract
Cut and fill mining is used in 13 of the 16 mines of Boliden Mineral AB. Systematic failure observations and in situ measurements in the Näsliden Mine provided insight into the type and magnitude of the rock mass reactions, the function of the fill and the mechanisms governing stope stability. Aiming at developing numerical models as a planning tool in mining, the necessary modelling technique was developed and the agreement of model reactions with mine behaviour examined. The application of the acquired understanding of cut and fill mining was applied to practical mining problems. These comprise the prediction of future mining conditions, evaluation of the various types of cut and fill mining and of the effectiveness of the various support measures. Ongoing and future developments are outlined.
