The role of the Holodninsky ore deposit in ensuring need of the Russian Federation in extremely scarce raw materials – zinc and lead is shown. Technical solutions for decrease in ecological risks at extraction of this ore deposit are considered. Conclusions are drawn on prospects of extraction of the Holodninsky ore deposit.
The analysis of factors complicating the development of the Kholodninskoye deposit within the catchment area of Lake Baikal is carried out. Organisational and technical arrangements implementation of which reduces ecological risks while mining this deposit are worked out.
Mining systems for ore bodies of different thickness are developed for the conditions of Cholodninskoe deposit. Ration parameters of mining system are determined.
The scheme of approach of evaluation of the stability of underground structures with account for seismic activity of rock strata is introduced. Some aspects of estimation of stability of underground structures under dynamic loads are also present. Methods of choosing the safe parameters of underground mining with account for seismic and tectonic activity of rocks are shown.
A complex of technology and organization methods to higher grade filling due to horizontal layers system of extraction rich ferrous metal ores for various stages of mining is presented.
