Sommaire: The application of telerobotics to mining is currently being employed in production systems around the world. While mining companies have dominated the pursuit to implement this technology, organizations within other industries have continued to search for ways in which telerobotics could support more productive and efficient operations within their environments. Widespread adoption, however, requires development of the technology to a level well beyond its current state.

Sommaire: Mining in highly stressed ground conditions has been an increasing challenge at Brunswick mine. After over 30 years of mining, there were two large regional pillars established on the 1000 m Level to support the ground for safe extraction of the surrounding ore. The South Regional Pillar contains about 5 Mt of ore and the North Regional Pillar (NRP) has about 3 Mt of ore.
In the fall of 2000, mining activities were suspended following a series of ground movements around the South Regional...

Sommaire: A pipeline syphon can be a simple and reliable alternative for water conveyance over earthfill dams, or other topographic features, as compared to otherwise more complex pumping systems or buried pipelines. In its simplest form, a pipeline syphon consists of an airtight pipeline constructed over the top of a dam or other high topographic feature, connecting a source pond to a receiving pond or channel. It typically includes a submerged intake, conveyance pipeline, priming device, flow rate...

Sommaire: In open pit and strip mining operations, a variety of mining equipment combinations may be employed for overburden stripping, primarily dictated by the structure and nature of the mineral deposit. In coal extraction bulk operations, such as those found in Germany, Russia, and Australia, bucket wheel excavator-conveyor combinations are used. In the United States, Russia, Canada, and the United Kingdom, dragline mining is common. In almost all countries, shovel-truck combinations are utilized...

Sommaire: In 1998, Atlas Copco released the RCS technology opening the way for a new generation of modularized and computerized drill. Drilling accuracy, information logging, and serviceability have all taken a quantum leap forward when compared with previous generations of drill rigs. The modularity also facilitates almost unlimited possibilities for the expansion and adaptation of drill rig functions.
The Atlas Copco product strategy defines three levels of machine automation: ‘basic’ with manual...

Sommaire: Controlling the level of impurities in copper refinery electrolytes is essential to achieving acceptable cathode purity. Purge of electrolyte to waste is not an entirely satisfactory remedy, since the cost of neutralization, hazardous solid waste disposal, and replacement acid can be appreciable. Recovery by evaporation/crystallization is also not ideal because of high capital, operating, and maintenance costs.
Based on a phenomenon called acid retardation, the APU® process employs ion...
