Korzh V. Mining saveresources of technologies of an actual mining on the basis of laws of an ore drawing with heterogeneous loose properties.

During of theoretical, laboratory and industrial reached is revealed, that being caving theore has, as a rule, heterogeneous loose prop-erties, the features of their formation are investigated; new laws of release caving ore with heterogeneous loose properties for the first time are revealed and is shown, that the figures of release of such ore have the pseudo-elliptic form; the laws of formation of parameters of pseudo-elliptic figures of release under action of complex influence of physical properties cavig ore, rock pressure and technological parameters are opened. In view of the specified laws are developed: a technique of definition of geometrical parameters of pseudo-elliptic figures of release and their separate elements, theoretical bases and practical ways of man-agement of release preloaded of ore with het-erogeneous loose properties; the new methods of an abatement of qualitative and quantitative losses of ore are offered at release. The new laws of release were by the basis for creation of effective variants saveresources of technologies of mining, which provide an essential decrease of a level of losses and contamination at extraction of ore with heterogeneous loose properties.
