GEOTECHNICAL RESEARCH OF THE ROCKS FROM THE TAILINGS DUMPS IN THE WEST OF THE JIU VALLEY REGARDING THE STABILITY OF THEIR SLOPES

Abstract

The extractive industry, through the specific activities it involves, has a significant geotechnical and ecological impact on the environment, with dominance at the local level, near the mining units through the storage of mining residues resulting from the extraction processes. The different parts of the mine: mining premises, mine waste dumps, industrial buildings, social buildings, roads, platforms can have end uses such as: reproductions in the agricultural and forestry circuit, creation of waste deposits, recreational areas, industrial parks, retention basins. The rocks that are stored in the dump are made up of an inhomogeneous material from a petrographic and granulometric point of view. The waste resulting from the preparations is represented by a mixture of clays, shale clays, gritty clays, coal shale, coal fragments. This paper presents the research of the rocks from the tailings dumps in the west part of Jiu Valley.
