Abstract:
Rates and sequencing of undercut production blasting, drawbell blasting, and mucking are key drivers of cave performance. Cave performance encompasses a range of factors, which include growth, shape and the effect of the cave on the abutments, excavations, geological structures and lithology. We calculate Spearman's rank correlation coefficient for time series of the seismic response in work areas, around geological structures, and in geotechnical domains in a block cave. These comparisons enable quantification of the relationship between production rates and seismic response.
