Development of a Repetitive Explosion Device for Rock Fracturing.
Abstract
The objective of the contract was to demonstrate that repetitive fuel/air explosions would augment the rock-fracturing capabilities of a standard D7F Caterpillar tractor with a parallelogram-type ripper. A standard D7 Caterpillar tractor with ripper was modified to incorporate a means of discharging high-pressure combustion gases near the point of ripper penetration of a rock formation. Testing of the D7/REDSOD Ripper was performed in two distinct types of Edwards Group Limestone. The results of these tests indicate that a REDSOD-augmented D7 Ripper will produce significant increases in production rate compared to that of the standard D7 tractor-in marginally rippable/unrippable material. This increased production is realized throughout the range of tractor-operating velocities.
