| Cone Fracture Rock BreakageChemical Excavation Methods | Penetrating Cone Fracture Rock Breakage. Tradename of "SunBurst" from Australia. State of the art, non-explosive chemical rock breakage technology for close proximity excavation applications in mining and civil engineering. Explosive system, cycle time of 6 mins, giving 0.33 m3 each explosion. A typical rate of 10 No cycles per hour, giving 3.3 m3/hr/rig. However, tests have shown differing results... Fresh granite of class 1 strength - One hole in the floor, yielding 0.15 m3 of rock. If more holes had been injected, a yield of 0.5 - 1.0 m3 would be expected. Moderately fresh igneous rock of class 2 strength - Three holes in a sloping trench, in adjacent locations, yielding 2.6 m3 of rock for each hole. Moderately weathered volcanic rock of class 3 strength - Two holes in the floor, in separate locations, yielding 1.2 - 1.5 m3 of rock for each hole. | 3.3 m3 per hrper hrParsed | Cone Fracture Rock Breakage |
