systems, giving them the sameflexibility as trackless arrangements. Monorail technology has been used in mining in South Africa for material and personnel transportation. Alsothe, technology has been developed in Jundee mining operations in Australia with the capability of hauling from the decline development (Chanda Besa, 2008).
The locomotive features a trolley system for overhead catenary operations and a traction power pack (battery or diesel). Power packs can be changed from one mode to the other in less than an hour. This type of equipment is being implemented at PT Freeport Indonesia''s Grasberg mine, which is currently in transition to underground mining.
Chapter 3: Hoisting and Material Handling Equipment — The Use of Cranes and Material Handling Tools Hoisting and moving heavy materials from one point to another around a job site requires the use of specialized machinery. In some cases, a crew may need to suspend the materials when building largescale projects such as industrial buildings, dams or skyscrapers.

Safety Considerations For Mine Hoisting Systems. changes in the design, operation and maintenance of mine hoisting systems In particular, in Australia, new hoisting, require new approaches to maintenance, including inbuilt expert systems for fault diagnostics and .
Underwind and overwind protection system concepts for mine hoist shafts were developed in conjunction with and for the Safety in Mines Research Advisory Committee (SIMRAC). Endofwind operation of mine hoists is the most hazardous aspect of mine hoisting, carrying the highest risk of loss of life, injuries to workers and loss of production.
Equipment recovery in surface mining operations has been improved dramatically with these highperformance slings. Super strong and ultra light, the Kspec fiber does not store energy, to the same degree as other materials. Subsequently the Mine Tow Strap does not dissipate stored energy and has very little, if any, whiplash effect at failure.
Railguided mine car systems are a safe and spaceefficient transportation method in underground mining operations. Mine cars transport products as well as materials in the shaft. High safety standards prevail in mine car operation thanks to guided and predefined movements of the mine cars with Voith TurboHoist Decking Devices.
Material Handling Systems Whether you''re mining underground or at the surface, we can help you move materials important to your operation. ... Shafts Hoisting Systems We have skilled shaft and hoisting experts who will work with you to tailor designs to meet your needs.
Apr 06, 2016· Mining hoists need to be totally reliable as they play a key role in transporting people and materials underground. In this regard, it is important to ensure that two important teams (the electrical and mechanical teams) work in coordination during mining operations. The combined efforts of these two teams keep the mining hoist up and running.
When hoisting performance is the limiting factor of mucking and hoisting operation, this is called the critical hoisting depth. Before starting the actual mucking and hoisting operation, the blasted rock has to be prepared for mucking operation and mucking equipment has be brought into position.
One of the worthiest advantages is a reliable and economic operation with almost no maintenance requirements and, as there is no watercooling, no risk of water leakage and damage of the system. As we live in a global world, our approach is also global and our hoisting systems are provided with the most uptodate monitoring system.
Both hard rock or soft rock underground mining operations demand the most resilient equipment and systems to allow for a safe removal and work environment. Its a tough job with even tougher conditions. We have the skill and safety reputation to support to keep Underground Mining Operations in motion.
