Excavator selection based on muckpile shape parameters in low height benches

摘要

Selection of excavator by knowing the muckpile shape can help in increasing the productivity of the machine and the safety of the operator. The present study which was conducted in limestone quarries where major problems such as of improper fragmentation, poor wall control, and poor heave characteristics of the muckpile were observed. The results obtained from this study indicate that the muckpile shape parameters and size of fragmentation largely affects the excavator cycle time.
