whole life of a mining operation, from its beginnings in the pre-feasibility study stage, through the operation of the mine, to the final closure and abandonment of the mine. The design of open pit excavations will endeavour to prevent hazardous and unexpected failures of the rock mass* during the operating life* of the open pit.
Surface Mining (Strip, Open Pit, Mountain top Removal) is used when coal is near the surface. Soil and rock overlying the deposit are removed to retrieve the deposit. Deep mining (underground) drills tunnels into the earth for extraction.
May 04, 2018· Bankable feasibility study (BFS): ... Strip ratio: The ratio of tonnes removed as waste relative to the number of tonnes of ore removed from an open-pit mine. For example, a 3:1 stripping ratio means that mining one cubic metre of ore will require mining three cubic metres of waste rock.
Waste Rock Dump Management and Stability Evaluation D Olivier SRK The management of mine waste dumps has historically been assigned mainly to the on-site mining operations. In recent years, focus has turned to a more scientific approach to waste rock dump management and the auditing of these manmade structures.
SRK was commissioned by the Tyhee Gold Corp. to compile a feasibility study including, project management and coordination, geology and resources, open pit mine planning and reserves, underground mine planning and reserves, geotechnical evaluation, economic modeling, and metallurgy at the Yellowknife gold project in the Northwestern Territories.

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.
Open-Pit Mining. Open-pit mining, or open-cast mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining.
Mining. Norway is renowned for its hard rock mining, both open pit and underground. From a mining perspective, the deposit supports a low-cost production operation due to: The high relief location of the open pit enables the use of a glory hole for open pit mining.

Open-pit, open-cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mining.Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface.
The Camino Rojo Feasibility Study considers open pit mining of 44.0 million tonnes of oxide and transitional ore grading 0.73 g/t gold and 14.2 g/t silver at a throughput rate of 18,000 tonnes per day. Ore from the pit will be crushed to 80% passing 28 mm, conveyor stacked onto a heap leach pad and leached using a low concentration sodium ...
Indicated categories which are the categories necessary to qualify a resource for a Feasibility Study. For this reason, the pit optimization was based on an "open pit only" option without considering the effect of breakeven open pit and underground costs.
Sep 26, 2013· Aitik open pit mine in northern Sweden is currently 430m deep. Bingham Canyon. Bingham Canyon mine located south-west of Salt Lake City, Utah, US, is the deepest open pit mine in the world. The Bingham Canyon pit is more than 1.2km deep and approximately four kilometres wide.
Apr 29, 2015· Over my career I have been involved in various types of mine studies, ranging from desktop conceptual to definitive feasibility. Each type of study has a different purpose and therefore requires a different level of input and effort, and can have hugely different costs. I have sat in on a few junior mining management discussions.
