Information estimate of natural geosystem preservation in geoconstruction

The area of the research is natural geosystem preservation in geoconstruction. The aim of the research is introduction of information assessment of preservaton level using total geoecological parameter in geoconstruction. Three features were chosen as the main geoecological information features of the estimate, prediction and geosystem preservation management, they are: natural raw materials consumption, fuel consumption and useful properties of a mineral geostructure with the end of the life-cycle. Rating method is suggested as a method of the rasearch;it includes conversion of the properties, using certain mathimatical operations into dimensionless values named index of properties. By determining weight factors with the help of expert assessment and bydetermining the sum of productions of indices and coefficients as total geoecological parameter, the study shows the relationship of the latter with the values of the real consumption of natural raw materials, fuel and useful properties of wastes with the end of the life-cycle of a geostructure. Also the study suggests the achieved levels of the preservation and predicted increase of the level takinginto consideration the total geoecological parameter. The results can be used for estimate of any geotechnology in the preservation aspect
