When mining steep deposits of Kryvyi Rih iron ore basin (Ukraine), a significant part of the reserves is lost in the “triangle” of the footwall. Complete extraction of reserves requires increased costs for mining ore. At present, there are option

The ore deposits in Kryvyi Rih iron ore basin are mined using bulk ore and overlying rocks caving systems. These mining systems have a significant drawback, namely a 2 – 5% reduction in the iron content of the mined ore mass when mining rich ores a

When mining ore bodies in Kryvyi Rih iron ore basin, underground mines apply open stoping or bulk caving systems in proportion of 55% to 45%. Most of underground mines prefer stoping with pillar caving. Yet, rock pressure contributes to growth of cos
