MINSK, 24 May (BelTA) – The construction site of the Nezhinsky mining and processing factory is getting prepared for drilling future shafts, BelTA learned from representatives of IOOO Slavkaliy, the company in charge of building the factory.
According to the source, the construction of the Nezhinsky mining and processing factory has reached one of the most labor-intensive phases — preparation for drilling future shafts. A tender has been held to choose the contractor, which is getting ready to drill freezing boreholes.
As many as 82 boreholes will go 156m below the surface to form a closed circuit. A cooling agent will circulate in the system for eight months to lower the soil temperature to 35C below zero. Such ice wall structures are used at the world's largest mines to fully prevent water from reaching future production shafts.
BelTA reported earlier that the groundbreaking ceremony for building the Nezhinsky mining and processing factory using the Starobinskoye potash salt deposit in Lyuban District, Minsk Oblast took place in September 2015. The Nezhinsky factory will become the country's second enterprise to extract potassium ore and produce potash fertilizers (up to 2 million tonnes of potassium per annum). As part of the investment project one mining facility will be built in addition to a processing plant, a gas turbine power plant the enterprise will need, railway infrastructure, motorways, housing infrastructure, and other kinds. The construction of the Nezhinsky mining and processing factory began in 2016. IOOO Slavkaliy is in charge of implementing the project.
