20100225155 | USE OF POST-BLAST MARKERS IN THE MINING OF MINERAL DEPOSITS - A method of mining a mineral deposit includes setting a plurality of explosive charges at spaced pre-blast locations in the deposit, wherein at least selected pre-blast locations also carry respective markers that are such that the post-blast location of at least a useful proportion will be detectable after explosion of the charges. After the charges are exploded to fragment the deposit, the post-blast locations of certain of the markers are detected to obtain an indication of the relative positions of selected components of the mineral deposit after the fragmentation of the deposit by the exploding of the charges. Also disclosed is a method utilising a plurality of markers arranged to emit a detectable signal after blast fragmentation, and detecting the post-blast locations by triangulation techniques employing a plurality of receiver detectors. A further aspect proposes the use of secondary explosive charges as post-blast markers. | 09-09-2010 |
