EVALUATION OF THE EFFICIENCY OF DEVELOPMENT OF MINERAL DEPOSITS TAKING INTO ACCOUNT THE PRINCIPLES OF SUSTAINABLE DEVELOPMENT
An assessment of the significance of a mineral deposit is made in relation to the recoverable value of their reserves in the bowels. Evaluating the efficiency of the development of mineral deposits means determining their final efficiency, taking into account the cost estimates of the environmental consequences caused by mining activities and its impact on the natural environment. This article is devoted to only one of the aspects of this problem - the study of the peculiarities of using the time factor in the environmental and economic assessment of the development of mineral deposits. In this regard, the time factor is promoted to the category of determining factors, therefore, it requires a more detailed and fundamental consideration. At the same time, one should consider time not in a general abstract form, but give it a concrete definition.

CHANGES IN THE STRESS-STRAIN STATE OF SLOPES DEPENDING ON THE CHANGE IN WATER INFLOW INTO THE RESERVOIR OF THE TOKTOGUL HPP
Changes in electricity generation at the Toktogul HPP in certain years, given the unchanged technical conditions for the operation of their equipment and the stability of the economic situation, largely depends on the flow of water to the section.One of the main reasons for the observed changes in the properties and state of rock massifs on slopes are filtration forces that arise when hydrological and hydrogeological conditions change, which depend on the water level in the reservoir.The influence of changes in the water level in the reservoir on the stress-strain state of the slopes in the Toktogul HPP has been determined.
