20100156167 | ORE EXTRACTION USING COMBINED BLAST AND THERMAL FRAGMENTATION - A process for extracting ore from a vein ( | 06-24-2010 |
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 |
20100276984 | SELF-STEMMING CARTRIDGE - A cylindrical casing ( | 11-04-2010 |
20100295359 | Collapsible Cushion - A method of mining a valuable metal or material in an ore body is described. The method comprises the steps of: a) placing a cushion in a stope whereby the cushion creates a void into which fragmented rock can expand during subsequent blasting operations for a second or subsequent panel; and, b) maintaining the void until blasting operations occur whereupon the void is caused to collapse to accommodate fragmented ore generated during blasting operations. | 11-25-2010 |
20120242135 | METHOD OF UNDERGROUND ROCK BLASTING - A method of blasting rock at an underground blast site in which boreholes ( | 09-27-2012 |
20130002003 | PROJECTILE - A rock-fracturing mining explosive element; said explosive element subjected to an initial spreading against a target surface on impact of said explosive element with said target surface; said explosive element so constructed as to control the rate of spreading and compression against said surface prior to detonation. | 01-03-2013 |

20130140871 | Ammonium Nitrate Fuel Oil Mixtures - The present invention relates to ammonium nitrate fuel oil mixtures, and includes compositions comprising (a) ammonium nitrate, (b) a fuel component, (c) a functionalized polymer component, and (d) an oil-soluble anionic surfactant, wherein the mixture of components (b), (c) and (d) form a gel that will not readily flow. The compositions of the present invention provide improve fuel retention and/or water resistance properties, particularly when the compositions use low quality porous prills of ammonium nitrate. | 06-06-2013 |
