- Abstract
Proposed the idea of increasing the yield of commodity blocks of rock mass by minimizing technological losses block products in the fields with a complex of natural occurrence of a separate entity , a limited system kruto- and dipping fractures ; increase productivity and reduce the cost of separation of monoliths from the array through the study of optimal height quarry face. The method of calculation of rational technological parameters of the combined method of preparation for the seizure of high stone block in the fields with complex geological conditions of mineral deposits on the basis of a two-stage scheme vysokoustupnoy mining array where the first stage is separated monolith using wire saw , and the second – on the overturned jobsite monolith blocks cut in trade with machines and stitch drilling
