Underground and open cut mining Underground Mining is generally used for areas where the mineral seam is too far underground for open cut mining to be of use. A tunnel, called a decline, is created to allow workers and machinery to reach the location of the minerals. Stope mining is used for most hard rock mining of.
Fig. 1, above shows an illustration of a Open Pit Surface Mine. The definition of a open pit mine is "an excavation or cut made at the surface of the ground for the purpose of extracting ore and which is open to the surface for the duration of the mine's life." To expose and mine the ore, it is generally necessary to excavate and.
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. For mining operations to be.
Sep 26, 2013 . The deepest open pit mines are scattered geographically across the world unlike the deepest underground mines, which are mostly concentrated in South Africa. The majority of the deepest open pit operations in the world are copper producing mines. Mining-technology profiles the world's top ten deepest.
May 4, 2016 . Full-text (PDF) | Planners' optimism (or maybe commercial necessity) means that most mine plans use equipment rates that are rarely achieved (Lumley and Beckman, 2009). This lack of understanding of what equipment actually moves is causing erroneous equipment forecasts, leading to incorrect mine d.

Open pit mining, as one of the two methods of production in the mining sector, seems to have a relatively more reliable operating environment, however, it also contains a number of hazards within itself. The hazards that must be considered in this production method are those caused by slopes, water income, machinery,.
Mining · Mining Techniques; Strip Mining. Strip Mining. Strip mining is a kind of surface mining. The ore is very near to the surface of the land but has one or more layers of rock and filth on top of it. To mine the ore, these layers have to be removed. The steps in strip mining are similar to open-pit mining. The steps are:.
This technology enables a radical change in the management of risks in open cut mining. This paper will present recent case studies of the SSR operation in coal and metalliferous mines. 1. INTRODUCTION. The management of risk to personnel, equipment and continued production associated with slope instability is one.
In many cases, logging of trees and clear-cutting or burning of vegetation above the ore deposit may precede removal of the overburden. The use of heavy machinery, usually bulldozers and dump trucks, is the most common means of removing overburden. Open-pit mining often involves the removal of natively vegetated.
that a low, mine operational cost does not always lead to value creation. This thesis highlights the concept called 'schemes of exploitation' into the mine planning activity. This concept refers to the deployment of the loading equipment within each pushback of an open pit mine and which ultimately determines the amount of.

Massive failures of pillars in underground mines, severe coal and rock bursts, open-pit slope failures, and roof and side falls all represent unexpected failures of the system to meet its design standard. These failures often result in loss of lives, equipment, and in some cases large portions of the reserves. Mining-related.
