“…The lignite produced is very important for the Greek economy and production cannot be suspended. The factors causing such movements are attributed to the complex geology and tectonics of the region, the process of the mining operations, environmental conditions or the geotechnical parameters of the ground [1][2][3]. Mine management decided that as long as the reasons for the slope instability are known and the movement can be monitored and critically assessed, mining operations could continue even on (slowly) moving slopes.…”

Abstract:The geotechnical challenges for safe slope design in large scale surface mining operations are enormous. Sometimes one degree of slope inclination can significantly reduce the overburden to ore ratio and therefore dramatically improve the economics of the operation, while large scale slope failures may have a significant impact on human lives. Furthermore, adverse weather conditions, such as high precipitation rates, may unfavorably affect the already delicate balance between operations and safety. Geotechnical, weather and production parameters should be systematically monitored and evaluated in order to safely operate such pits. Appropriate data management, processing and storage are critical to ensure timely and informed decisions.This paper presents an integrated data management system which was developed over a number of years as well as the advantages through a specific application. The presented case study illustrates how the high production slopes of a mine that exceed depths of 100-120 m were successfully mined with an average displacement rate of 10-20 mm/day, approaching an almost slow to moderate landslide velocity. Monitoring data of the past four years are included in the database and can be analyzed to produce valuable results. Time-series data correlations of movements, precipitation records, etc. are evaluated and presented in this case study. The results can be used to suc-*Corresponding Author: Zacharias Agioutantis: University of Kentucky, Department of Mining Engineering, Lexington, Kentucky, USA; Email: zach.agioutantis@uky.edu Chrysanthos Steiakakis: Geosysta Ltd; Greece; Email: c.steiakakis@geosysta.com Evangelia Apostolou, Georgia Papavgeri: Geosysta Ltd; Greece Achilles Tripolitsiotis: Technical University of Crete, School of Mineral Resources Engineering, Geodesy and Geomatics Engineering Laboratory, 73100 Chania, Greece; Email: atripol@mred.tuc.gr cessfully manage mine operations and ensure the safety of the mine and the workforce.

“…The influence of rainfall on the slope stability of open-pit coal mines has long been identified and considered for design purposes. The effect of rainfall on the slope stability of coal mines has been primarily based on observations and empirical correlations between precipitation rates and slope movements [3]. This type of analysis is practical but limited with respect to current knowledge and challenges related to postmining hazards.…”

As the world transitions away from coal, vast areas of closed coal mines and waste dumps must be appropriately reclaimed. One critical element for these areas’ safety is slope stability, given the massive slopes of these mines and dumps. This work examines the effect of extreme rainfall on coal mines’ slopestability by incorporating unsaturated soil mechanics principles in a practical way. Past extreme rainfall events recorded for a Greek lignite mining area were used, and climate projections concluded that this intensity is not expected to change. Then, rainfall infiltration was simulated using the Finite Element Method; a typical slope was employed concerning a lignite mining excavation of 200m height and 14° inclination on fine-grained soils. Finally, the stability was calculated using the Limit Equilibrium Method. Rainfall infiltration caused the Safety Factor to decrease, leading to failure. The groundwater rose at theslope’s face from the slope’s toe upwards and led to the development of a smaller and more local than the initial (before rainfall) sliding surface with a lower Safety Factor. Although this is a smaller surface than the initial one, it is still more than 50m high, proposing a significant hazard with severe consequences for the area.
