The slope movement has been found to be greatly affected by
the periodic precipitation and the infilling of the tension cracks.
Based on the regressive typeof movement, the mining
operation could continue and at the same time remedial
measures taken with excavation of the top benches for
unloading. This remediation decreased but did not stop slope
movements. Although the slopes have moved more than 3m
horizontally, they are still in operation without significant
problems. Movements were found to be very sensitive to
external conditions such as precipitation.
