| 141 | METHOD AND APPARATUS FOR CHARGING A HOLE | EP99966764 | 1999-12-14 | EP1144943A4 | 2002-05-22 | GAVRILOVIC MIHAILO; MICKE BRIAN |
| A method of charging hole (12) drilled in rock or concrete (10), the method including inserting a quantity of energetic material (14) on or near the bottom (16) of hole (12). Lead (28) connects initiator (18) with an initiation source at ground level. Hole (12) is filled with stemming material (20) to a level (L) and plug (22) is positioned to rest on stemming material (20). Lead (28) threads through plug (22) via a slot, recess or passage. Mass (30) such as the bucket of excavator (32) and plug (22) prevent stemming material (20) from being blown out of hole (12) when energetic material (14) is detonated. The risk of collar area (C) being fragmented and energised to produce fly rock is reduced since the length of plug (22) is commensurate with the length of collar area (C). Plug (22) and stemming material (20) can be replaced by a stemming bar, with the stemming bar attached directly to energetic material (14). | ||||||
| 142 | METHOD OF BREAKING SLABS AND BLOCKS OF ROCK FROM ROCK FORMATIONS AND EXPLOSIVE SHOCK TRANSMITTING AND MODERATING COMPOSITION FOR USE THEREIN | EP98909971 | 1998-01-09 | EP0951634A4 | 2002-05-02 | WATHEN BOYD J |
| Rock slabs (10) or pieces (17) are broken from large rocks (10) or from rock formations (11) with reduced cracking of the broken rock slabs or pieces by drilling bore holes (13, 14, 15, 16) along the desired break lines, placing detonating cord (20) into the bore holes, filling the bore holes with a shock transmitting and moderating composition (21), and detonating the detonating cord (20). The shock transmitting and moderating composition (21) is preferably a gel with shock absorbing material (22) such as microspheres or micro gas bubbles suspended therein. Openings in rock can also be formed by drilling at least one bore hole within the desired opening and drilling a plurality of bore holes along the desired periphery of the desired opening. Explosives within the at least one bore hole within the desired opening is detonated to break rock within the opening and detonating cord (20) in the bore holes along the desired periphery of the desired opening which holes are filled with a shock transmitting and moderating composition (21) is detonated to break the rock inwardly of the desired periphery while leaving stable the rock outwardly of the periphery. | ||||||

| 145 | METHOD AND APPARATUS FOR CONTROLLED SMALL-CHARGE BLASTING OF HARD ROCK AND CONCRETE BY EXPLOSIVE PRESSURIZATION OF THE BOTTOM OF A DRILL HOLE | EP96935776.0 | 1996-08-02 | EP0842391A2 | 1998-05-20 | WATSON, John, David |
| Rock and other hard materials, such as concrete, are fragmented by a controlled small-charge blasting process. A cartridge (200) containing an explosive charge is inserted at the bottom of a short hole (240) drilled in the rock. The explosive charge is configured to provide the desired pressure in the hole bottom, including, if desired, a strong shock spike at the hole bottom to enhance microfracturing. The cartridge (200) is held in place or stemmed by a massive stemming bar of high-strength material such as steel. The cartridge (200) incorporates additional internal volume designed to control the application of pressure in the bottom hole volume by the detonating explosive. The major features of the method and apparatus are the relatively low-energy of the flyrock and the relatively small amount of explosive required to break the rock. | ||||||

| A borehole decking plug which is created by a self-expanding plastic foam. Two closed waterproof pouches, an inner pouch (101) and an outer pouch (103), each contain a separate component (107, 109) of the foam. The inner pouch (101) is contained within the outer pouch (103), and both (101, 103) are contained within a third open external pouch (111) having a tether attachment (115, 125). Upon breaking the inner pouch (101), the separate foam components (107, 109) combine within the outer pouch (103) to form a complete expansion foam. The foam expands slowly enough to provide sufficient time for the device to be lowered via the tether (129) down a borehole to a preselected position. Once in position, the expansion foam bursts the outer pouch (103) and escapes upward through the external pouch (111) to form a deck plug at the preselected position. | ||||||

| A packaging system for explosives having a thin walled water resistent tube (11) containing a low-sensitivity explosive (65) therein. A first cap (33) is fitted about one end of the tube and has a re-entrant portion (30) that projects into the tube about which the explosive material (65) is filled. The other end of the tube is sealed with a second cap (16) to create a substantially water-tight explosive package. An initiator is received within an open-ended cavity (37) formed in the re-entrant portion (30) of the first cap and is detonated for setting off the explosive charge. | ||||||

| A method of blasting rock, in mining for recoverable material, comprising drilling blastholes in a blast zone loading the blastholes with explosives and then firing the explosives in the blastholes in a single cycle of drilling, loading and blasting. The blast zone comprises a high energy blast zone in which blastholes are partially loaded with a first explosive to provide a high energy layer of the high energy blast zone having a powder factor of at least 1.75 kg of explosive per cubic meter of unblasted rock in the high energy layer and in which at least some of those blastholes are also loaded with a second explosive to provide a low energy layer of the high energy blast zone between the high energy layer and the adjacent end of those blastholes, said low energy layer having a powder factor that is at least a factor of two lower than the powder factor of said high energy layer. The high energy blasting method provides improved rock fragmentation through increased explosive energy concentration while simultaneously alleviating deleterious environment blast effects. | ||||||
