Engineering-geological zoning for estimation of stability of rocks of quarry fields (on the example of Tikhvin mining district)
Abstract
Variability of geological structure, hydrogeological conditions and physical and mechanical properties of rocks is characteristic of open pit mine fields of many mineral deposits. Often the thickness of the rocks to be excavated also varies significantly. All this leads to variability of rock stability conditions in the slopes of mine workings in one open pit field. In such cases, based on the analysis of natural conditions to justify the design solutions of open-pit mining, it is advisable to subdivide (zoning) quarry field into areas with similar engineering and geological conditions that determine a unified approach to the design and organization of mining operations. Let's consider such zoning in connection with the assessment of rock stability on the example of quarry fields of the Tikhvin mining district ...
