Dipper door retarding mechanism

The SnubbPack snubber system designed to braking the door dipper on the large rope shovel. Designed on the principle caliper brake, capacity and versatility of the invention are that the brake system is adaptable to any type of equipment.. The enormous cylinders are controlled by an accumulator and a bank valve sytem, allowing him to remain effective and allows at the same moment an adjustment of the pressure by a small portable power pack. Set apart its robustness unequalled, the system applies

Scanning System for 3D Mineralogy Modelling

A method of mining comprising: using a vehicle fitted with scanning module t o scan a bench face of a mine bench for both geometric and geological information; making o re grade assessments of material at the bench face from the information provided by t he bench face scan; removing material from the bench; and transporting removed material fo r processing. At least one of said removing, transporting, and processing is performed at lea st partially dependent on the ore grade assessments.

Portable Robot Mine Detection and Classification System

Most mine clearing operations require that a human operate a mine detection apparatus. This places the human in mortal danger. To date no mine detection devices have a 100% probably of detection capability and a low false alarm rate. Mine clearing must be done quickly and therefore adds an additional element of stress to the human operator. Non lethal metal objects also slow down the operation. The researchers at The Johns Hopkins University Applied Physics Laboratory have developed a small r
