МЕРОПРИЯ ТИЯ В ЧЕСТЬ ПРАЗДНОВАНИЯ 76-Й ГОДОВЩИНЫ ВЕЛИКОЙ ПОБЕДЫ В честь празднования 76-й годовщины Великой Победы Советского Союза в Великой Отечественной войне 1941-1945 гг. разрез «Черногорский» ООО «СУЭК-Хакасия» провел парад по центральным улицам г. Черногорска с участием макетов и реставрированных образцов техники военных времен. Все участники парада были одеты в военную форму времен Великой Отечественной войны (рис. 1).
Chernogosky open pit mine integrates truck-and-shovel system of mining with overburden rehandling to internal dump with a set of walking excavators for rehandling of overburden to mined-out area of the pit. It is possible to improve efficiency of stripping in the conditions of Chernogorsky OPM by reducing percentage of stripping with more expensive handling system. The relevant research and solutions to this effect are presented in this article. Comparative characterization of mining conditions and parameters of mining systems applied is given for open pit mines Chernogorsky, Turnui, Nazarovsky, Vostochno-Beisky and Izykh. The comparative analysis points at the need to account for difficulty of mining and process sites in comparison of equipment productivity. High concentration of mining machines, which is conditioned by narrow mining front and simultaneous operation of five faces, as well as blasting operation implemented every 1-2 days, are recognized as the main constraints of excavator capacity in mining with direct dumping in Chernogorsky open pit mine. The management and engineering solutions implemented in the mine and resulted in higher efficiency of draglines are described.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
