Abstract:Iron ore deposits currently being mined and those which may be mined in the future in Siberia using underground mining methods have various geomechanical conditions.A considerable part of the prospective reserves are situated in deep sections covered by rocks with a thickness of more than 250-300 m. The steeply dipping ore deposits have a length over the strike up to i000 m, a thickness of 20-300 m, and a width of about 600 m.The hardness of the ores and surrounding rocks limits extensive use of an ore caving … Show more
