Annotation	The article presents several measures of ash control improvement in relation to the conditions of the Elginskoe coal deposit on the basis of a new concept of «natural dilution of coal» and components of ash content. In particular, this can be achieved by: increasing of the extraction ratio of reserves of complex structure seam, taking into account the coal ash in the contact zones (distribution of coal ash in the zones of contact of the roof and bottom of seams with a thickness of 1 m with overburden for the major seams in the priority of mining of the deposit is investigated); selective extraction of rock layers from the seams or separate mining extraction from areas with different mineralization (there is a possibility for additional differentiation of coal reserves to more homogeneous technological zones with higher or lower number of interlayers for organization of simple (areal), complex (by thickness) or joint separate excavation and formation, if necessary, independent or combined coal flows); extraction of coal or rock interlayers for mining of the thickness seams (patented method for extraction a part of the off-balance reserves almost without changing an order of mining operations, and to carry out an excavation of rock and high ash interlayers from minable coal seams); separate excavation of coal seams with different ash (recommendations for the extraction of seams with differences in ash between the vertically allocated zones by dividing into multiple benches with the formation of independent coal flows with different ash and preparation are given). The directions of further researches are suggested
