Oct 01, 2015· How safe is your mine hoist? Mine hoists are responsible for the safe transport of people and material underground so they need to be 100 per cent reliable. Keeping the hoist up and running requires more than any other item of mining equipment the skills of two diverse...
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.
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).
But as to the relative merits of the system of mining in the two cases, nothing could be decided without a basis of detailed comparison ; if one system is more economical than the other, why is it so, and wherein does the advantage lie ? This can be shown only by keeping accurately the cost of each mining operation.

In underground mining a hoist or winder is used to raise and lower conveyances within the mine hoists are normally powered using electric motors, historically with direct current drives utilizing Ward Leonard control machines and later solidstate converters (), however modern large hoists use alternating current drives that are variable frequency controlled.
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.
Dec 21, 2015· The material is then conveyed to a central conveying system which will take it directly to the surface or via a skip and hoist system. Blasting equipment is used for both underground and open pit mining operations and is known to be one of the most hazardous aspects of the job.
the most important unit operations in any underground mining process. In this way, the hoist becomes the single most critical asset of the entire operation because it can expose the productive health of the mine site. In other words, the hoist—as the single operating equipment working between upstream mining and down

The hazardous conditions of underground and opencut mining call for rugged materialhandling equipment that is built to endure moisture, corrosion, abrasive dust and ignitable fumes. At Konecranes, we understand the challenges of mining and the problems caused by equipment downtime.
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.
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.
