Ventilation of cleaning blocks at Zapolyarny mine

Abstract

The Zapolyarny mine widely uses high-performance mining systems with massive ore collapse when mining a thick declivity ore deposit. This is associated with the need to detonate large explosive charges during ore stripping and release and, consequently, with the contamination of the atmosphere of underground workings. For the organization of effective ventilation of treatment blocks is important properly designed ventilation scheme and systematic fight against the causes of deterioration of atmospheric conditions at workplaces ...
