Abstract
Large-scale mining methods are taking over the leading role in exploitation of low-grade and deep mineral deposits considering its high productivity, low cost, and satisfying ore recovery and ore dilution. In order to improve properties of existing block and sublevel caving methods, researches were carried out in laboratory conditions on physical model of similarity. Results of the research, the determination of optimal parameters and indicators for the new variant of the caving mining method is discussed in this paper. Experiments were based on ore drawing for the case with two and three one-sided lateral loading chambers and they were performed in order to determine the best combination between variable parameters of block width and spacing between loading chambers that would give the most optimal results for ore recovery and ore dilution.
