Abstract

A study of the feasibility of induced slope stability failures in strip mine waste piles is presented. Slope failures were induced in laboratory models by applying water under pressure into perforated injection tubes placed into the simulated waste pile slopes. The holes were oriented to produce hydraulic fracturing along the most optimum plane for economic relocation of the spoil material. The models were constructed of waste pile material collected from strip mine sites in southern Illinois and central Missouri. The materials tested were from active as well as inactive mines. The model waste piles were constructed to approximately one-fifteenth the size of the average waste pile configuration and were compacted to match measured field densities. Horizontal and vertical permeabilities of the model waste piles were measured. Triaxial undrained shear strengths and the associated pore pressures were measured. These results are summarized and used in the stability analysis.
