GroundWater Problems in OpenPit and Underground Mines

Ground water constitutes a significant operational problem and potential hazard in openpit and underground mining. The pressure of ground water in geologic discontinuities adversely affects the safety of height and slope angles of openpit mines, justifying measures to reduce groundwater pressures in their vicinity. The principal hazard in underground mining and tunneling .

Open Pit To Underground Transition | SRK Consulting

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 largescale 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 ...

Optimizing the Open PittoUnderground Mining Transition

An early transition model assigns large aggregated blocks to be extracted via open pit or underground mining methods in order to maximize value of the deposit (Bakhtavar et al., 2008). This idea was later improved to include the time element and to capture underground capital costs (Newman et al., 2013). In both previous transition models, there is little di erentiation .

The Mining Process

The ore now goes through a threestage processing cycle to ensure the gold is economically recovered from the ore. Stage 1: Crushing and Grinding Ore stockpiled from underground and open pit mines is fed into the primary crusher at the process plant. The jaws inside crush the rock down to fit through the 125mm gap at the bottom.

Openpit mining is a technique that involves drilling into the earth's surface to set explosives. These explosions create a large pit for miners to access underlying rocks. This surface mining technique can be used to extract silver. Quarrying. Quarrying is a process in which miners cut blocks of hard stone.

 · The open pit mine will be smaller than other similar operations. "The size of the open pit length may be less than 2 kilometers. So it's not a big crater as such," Pangilinan said. "It's not a big pit as such. So after ten years, more or less, we have to go underground, so it's not a longterm open pit operation as such," he added.
