From Climate Conditions to the Numerical Slope Stability Analysis of Surface Coal Mines

A new perspective is presented for evaluating the slope stability of coal and lignite mines due to rainfall. The case Greek mining areas employed illustrate methodology. Initially, past climatic records rainfall are documented analyzed; intensity varies from light (0.8 mm/h) heavy (up 9 mm/h). Few extreme phenomena documented, with maximum being 17 mm/h. Furthermore, projections future trends performed open-access tools anticipate possible deviations baseline conditions. Although mean temperature expected increase, show that range not change. Finally, effect infiltration on a typical open-pit investigated by finite element analysis. precipitation defined environmental analysis used. SF practically constant lower intensities (0.8–2.2 For higher 6.4 mm/h, decrease almost same (from 2.08 1.9), reduction rates 8.3%, 8.9%, 9.3%, respectively. critical geotechnical properties—groundwater table depth, unsaturated zone properties, soil permeability—is also examined complete evaluation.
