Abstract

The depth of open-cast mines is continuously increasing to meet the production as per the high industrial demand. As a result, slope failure problems in open-cast mining are gradually becoming severe. Rockfall is among the most common failure associated with such high and steep slopes posing huge risks to minors and machinery. In the present study, the rockfall problem in the final high walls of a stone quarry is taken up to understand the rockfall mechanism associated with high walls in opencast mining. Field-based rock mass and block characteristics have been done along with kinematic analysis to identify the rock type failures and their stability condition through Slope Mass Rating. Initially, the rock fall parameters were back-calculated and validated through trajectory simulation of past rockfall events. Then the potential rock falls from the high walls have been simulated to assess the associated hazard through rock fall parameters such as block trajectories, total kinetic energies, and maximum runout distance of fallen blocks. An optimized slope geometry of the final high walls of the mine has also been proposed to minimize the rock fall risk in future mining operations.
