The safety of the open-pit overburden dump slope largely depends on the geomaterial size and shape. The shape of these geomaterials contributes to their shear resistance against sliding. The present investigation proposed a method to characterize the geomaterial using the digital image processing technique. The resources invested in this work are a simple digital camera and a computational toolbox. The system estimates the size distribution of geomaterial. The study also proposed a methodology for recon-structing the 3D geometry of the mine dump from the images. The advantage of the method is a low-cost, quick assessment of the dump geomaterial, and outcomes can easily be used in a numerical toolbox. The study was conducted in Barakar Valley Coalfields, West Bengal, India. The geomaterials above 4 mm sizes are considered in this work. The results matched the mechanical sieving output of the particle size distribution curve.
