Safety Evaluation Technology for Waste Dump Landslide of Open-Pit Mine Based on Fuzzy Mathematics

Abstract:

In recent years, frequent waste dump landslides brought the huge losses. Now, there is no mature theory system about the research on waste dump stability, this paper puts forward a disaster evaluation method for waste dump landslide which bases on fuzzy mathematics principle, the evaluation method is convenient and practical. Firstly, we established evaluation indicator system on the basis of analyzing landslide influence factors; first grade evaluation indicators included engineering geology, hydrogeology, dumping process and other factors; second grade evaluation indicators included geotechnical properties, foundation soft rock, foundation slope, atmospheric precipitation, underground drainage, drainage facilities, dumping way, dumping order, propulsion speed, mining disorderly, blasting vibration and force majeure. Secondly, we used analytic hierarchy process (AHP) to determine the indicator weight. At last, combining with the actual situation of some waste dump and using fuzzy mathematical theory, we had the safety evaluation to waste dump landslides, the result is in good agreement with the actual situation and shows that the method is a scientific guidance to the safety management of the waste dump.
