Method of regulation of losses and contamination of ore is offered for specific conditions of underground mining of kimberlites with application of descending mining, continuous ore mining and stowing by solidifying compounds. The algorithm of realization of this method is also given. There are shown the researches, natural experiments and measurements on definition of places of formation and types of losses and contamination, which were carried out in the conditions of Aykhal mine of «ALROSA» JSC. There is given the range of places and sources of losses and contamination. Empirical dependences are defined for calculations of regulation values of losses and contamination. Methodical approach of regulation of losses and contamination, developed on the basis of the offered method, takes into account the technological and design peculiarities of layer system of development with solidifying stowing and continuous mining of ore. At the same time, there appears the possibility of improvement of process of regulation of indices of ore extraction from subsoil, due to the usage of computer technologies.
