Typification of hydrogeological conditions in mineral deposits by system analysis method

Abstract

The paper presents a non-standard approach to the typification of mineral deposits in Eastern Siberia (Russia) according to hydrogeological conditions under insufficiency and unevenness of the initial information. The most rational way to solve this problem at initial research stages is to identify a number of easily determined indirect indicators that determine the selection of sites promising for drilling hydrogeological wells. The author uses the method of system analysis including two main stages of analysis and synthesis, which result in the typification of the objects under study in accordance with the assigned tasks. The developed methodology is used for various purposes: structural hydrogeological zoning of the Ilim-Lena plateau with associated main iron ore deposits of Eastern Siberia, typification of alluvial deposits of the Lena gold ore region according to the complexity degree of engineering hydrogeological conditions, identification of the sites with high water abundance in the oil and gas fields of Eastern Siberia.
