Physical properties of a large-scale stock pile of iron ore were in-situ investigated during its stacking and reclaiming process. The total weight of the stock pile was around 200 thousand tones. The stacking and reclaiming process lasted for 480 hours. The tested physical properties include angle of repose, size and shape data, and size distribution of the blending ore, etc. At the initial stage of the stacking process, the angle of repose was 37.1. A decreasing trend was observed as the stacking process proceeded. In vertical direction, particles at bottom are much coarser than that at upper layer. In longitudinal direction, the head and tail section (5.7 m in length) of the stock pile showed serious particle segregation. According to the testing results during the reclaiming process, the deviation of the particle size at the cross section of the stock pile was above 10 %.
