University of Tehran International Journal of Mining and Geo-Engineering 2345-6930 47 1 2013 06 01 Stability Analysis and Stabilization of Miduk Heap Leaching Structure, Iran 1 11 50086 10.22059/ijmge.2013.50086 EN Mehdi Amini School of Mining, College of Engineering, University of Tehran, Tehran, Iran Journal Article 2012 11 20 To construct copper heap leaching structures, a stepped heap of ore is placed over an isolated sloping surface and then washed with sulphuric acid. The isolated bed of such a heap consists of some natural and geosynthetic layers. Shear strength parameters between these layers are low, so they form the possible sliding surfaces of the heaps. Economic and environmental considerations call for studying such slides. In this study, firstly, results of the laboratory tests carried on the materials of the heap leaching structures bed are presented. Then, the instability mechanisms of such structures are investigated and proper approaches are summarized for their stabilization. Finally, stability of the Miduk copper heap is evaluated as a case history, and appropriate approaches and their effects are discussed for its stabilization. https://ijmge.ut.ac.ir/article_50086_77b615b26e8e1e57c1f2ff86f7bb43a5.pdf
