Substantiation of Continuous Equipment Efficient Choice at the Selective Mining of Passing Minerals

Abstract

Article deals with the actuality problem of continuous equipment efficient choice at the open cast mining when selective mining deposits. Analyses the advantage of bucket wheel excavators using at the selective mining of passing minerals. The parameters of face cut and bucket wheel that allow to increase the effectiveness of selective extraction technology by the bucket wheel excavator is calculated. The dependence of the rational use of bucket-wheel excavator types on it bucket width is determined. The results of the conducted researches show that the excavation of overburden layers with thicknesses that equal or more then selection degree is effective.
