Innovative orientation of resource saving in development of placer deposits

The problem of saving geo-resources is a constant task of the state bodies responsible for the state of the mineral resource base of the country. Conservation of geological resources in the development of natural placers is realized in modern conditions with the use of geoinfomation technologies that allow for the computer planning of placer development to additionally extract productive mining mass from near-contact zones based on the breakeven condition of its extraction. The completeness of the extraction of reserves from the placer is associated with a preliminary assessment of the content of the useful component and the subsequent development of natural and man-made formations formed from security tails and tails adjacent directly to the natural growth, intra-contour, unfinished and partially or completely buried under the dumps of zones and near-site areas, tailings processing of concentrate and alluvial deposits that occur as dumps and residual intact areas are washed away. It is advisable to display the spatial relationship of factors by matrix correlation functions describing the linear, areal and volumetric connectivity of geodata. Mathematical modeling of technogenic formations, taking into account the spatial connection of geodata, is implemented by constructing 2D and 3D maps. The initial spatial and attributive geodata are the results of geological testing of the object.
