Mining
Underground mining. Ore is extracted from LKAB's underground mines by means of sublevel caving. This mining method is based on creating cavities in the orebody through drilling and blasting, and allowing the ore to fall down to underlying levels by means of gravity, from where it is transported onwards by train or loader.

· The Skalistiy mine came on stream in the late 1990s at a cost of around 600m, and Glubokiy mine is now under development – these two units alone have reserves of some 70Mt of ore. Norilsk Nickel also operates the Kayerkanskiy opencast coal mine, some 30km from the city, to supply power station fuel; the operation uses two R992 hydraulic excavators and a fleet of Belaz 40t .

"Raise Caving" – Cheaper and more flexible mining at great ...
· Massmining methods, such as block caving or sublevel caving, enable lowcost and efficient mineral extraction, but these methods are associated with high capital cost and risks. Latter mining methods call for mine planning and decision many years in advance. Moreover, block caving and sublevel caving are difficult to apply in at great depths due to the high prevailing stress conditions.

· • Lowest mining cost per ton: Block cave mining operating costs are a fraction in comparison with any other underground mining method. • Flexible production rate from cave mining methods: Block cave mining is driven by economies of scale, where production rates can reach up to 100 kilotonnes per day; however, there are smaller mines working successfully with lower production rates .
