Abstract

This work is divided into three main parts. First part defines the basic parameters of muck conditioning and parameters of muck for her possibility of use as media support to ensure the stability of the face. The second part describes the current volume and mass methods of determining the amount of mined muck. It describes the procedures for setting limit values mined muck that allows to evaluate the quality of the coinage in terms of creating overbreaks. The last part is devoted to the analysis of data from measuring the mass of muck during the excavation of the fifth operational section of Line A of the Metro. Evaluated here is the relevance of measured values and based on the knowledge of geology and regulating the amount of added ingredients in individual shots also overbreaks formation during the excavation.
