Abstract

The underground extraction of deposits with coal-plough machines using for the mine destruction is the long-range outlook because of the full workflow automation. The grave disadvantage of mechanical destruction is heavy energy consumption on separation of. The authoring is evidence of the possibility of the coal-plough machines creation with a new principle of ore separation on the basis of the big debris ore break off. The principle is developed in SPMI and it’s permitted to reduce energy consumption on the ore destruction in comparison with legacy domestically produced and world-wide prototype.
