LARGE SCALE SLOPE STABILITY IN OPEN PIT MINING A REVIEW
open pits continuously increase. Small changes in the overall pit slope angle have large consequences on the overall economy of the mining operation. A case in particular is the Aitik open pit mine in northern Sweden, which currently faces the design of the overall slope angles for continued mining toward a depth of around 500 meters.

most obvious has been the increase in the scale of operations as higher capacity equipment has been developed. For instance, in the 1920s, a mining shovel with a 5 m 3 bucket was exceptional. Today, large openpits use rope shovels or hydraulic excavators with bucket sizes of ten times that capacity.

Advantages and disadvantages of open pit mining –
Open pit mining is profitable when the deposit is not very deep or when the terrain is sandy or delicate, so that underground mining is not possible. Labor costs are lower, both in excavation and transportation, and allow the use of large machinery .

Oil Sands Extraction and Processing
Currently, 20% of oil sands reserves are accessible via mining techniques. Large shovels scoop the oil sand into trucks which then move it to crushers where the large clumps of earth are processed. Once the oil sand is crushed, hot water is added so it can be pumped to the extraction plant. At the extraction plant more hot water is added to

Open Pit Mines
At the end of an open pit operation, sump pumps and/or dewatering wells are decommissioned. The geometry of the pit and the void volume may be modified if partially backfilled with mine waste. Following cessation of pumping, in most climatic regimes, both surface water and groundwater will inflow to the pit, creating a pit lake (Figure 19).
