Open Pit To Underground Transition
Categories. SRK carried out a scoping study on an existing open pit operation 12 Mtpa that is soon to be reaching a depth where the mine will need to transition to a large scale underground mining method. The goal was to provide production continuity at a rate that will still be suitable to maximise use of the existing surface processing Get Price
Open Pit to Underground
Open Pit to Underground Transition and Interaction Many ore deposits have considerable vertical extent which is not always known at the time of commencement of mining. In many of Get Price
Mining Sites: The Transition from Open Pit to
2019 7 10   This transition from open pit to underground begins when open pit mines are exhausted or inaccessible; meaning, they have either been depleted of minerals, rocks, and resources, or they are unfeasible to build upon. Once the Get Price
Timing of transition from open pit to underground
In this case, mine planning and optimisation play a significant role in the decision making. This paper proposes a mixed integer programming model to obtain the optimal transition point and Get Price

THE TRANSITION FROM OPEN PIT TO UNDERGROUND
2006 3 22    ICCI undertook a programme of 3DEC numerical modelling of the Palabora open pit walls and floor. The purpose of the work was to investigate mechanisms of slope deformation and failure of the pit walls, and the possible relationship between apparent pit wall instability, and the block cave mining taking place beneath the base of the pit.

Issues with transitioning from open pits to underground
Abstract: This paper covers the issues and trends associated with transitioning from an open pit operation to an underground caving mine. The decisions made on the timing of the transition affect many parameters including the Mineral Resources Resources and Ore Reserves Reserves, the timing and costs associated with the studies required to support the change.

Planning Considerations For Transition From Open Pit To

Planning Considerations: The efficient transition from open pit mining to an underground operation requires extensive planning. For a large mining operation, planning could last as long as 20 years. The main factors and activities that need to be taken into account in the planning cycle are as follows: Definition of the ore body. Get Price
Timing of transition from open pit to underground
Generally, shallow deposits are mined through open pit mining and where the deposits are extended to a substantial depth, there is a potential for a combination of open pit and underground mining methods. In this case, mine planning and optimisation play a significant role in the decision making. Get Price

Open Pit to Underground
Open Pit to Underground Transition and Interaction. Many ore deposits have considerable vertical extent which is not always known at the time of commencement of mining. In many of these cases, initial mining is by opencast methods, and as ore reserves are proved to greater depths, the pits are often planned to go deeper than had been Get Price
