Procedure and Example of Grade Control in Open Pit Mining. Conference Proceedings. Procedure and Example of Grade Control in Open Pit Mining Add to The factors at play are many, starting from a good analysis of the geology and a correct sampling procedure. Once this is achieved (and it is an essential prerequisite), the problem is
Step 6 Clean up process . Just like at a party, once the exciting part is over, somebody has to stay behind and clean up the mess! In underground mining, the tunnel will be cleared of debris, and the tunnel will be suitably reinforced. Otherwise, as in open
Openpit mining which is sometimes referred to as open cut mining, opencast mining or simply strip mining is a mining technique that extracts important minerals from a borrow or an open pit. There are two types of mining methods commonly used in large scale mineral mining; open pit mining and tunneling. Open pit mining is []
In the open pit the trucks take their loads to the primary crushers or to stockpiles. In the underground mine the ore is taken to stockpiles at the processing plant, while waste rock is stockpiled for reuse as backfill once mined areas are completed.
The open pit exposes the orebody from the surface by separate removal of ore and associated waste rocks. It is the most economic option for a deposit up to that depth where the economic ratio of ore and waste can be sustained. There are many advantages to the open pit mining method, namely: 1.

Openpit mining, also known as opencast or open cut mining, is a surface mining technique of extracting rock or minerals from the earth by their removal from an openair pit, sometimes known as a borrow.. This form of mining differs from extractive methods that require tunnelling into the earth, such as long wall mines are used when deposits of commercially useful ore or rocks
Open pit mines can be used in coal mining, and they are used extensively in quot;hard rockquot; mining for ores such as metal ores, copper, gold, iron, aluminum, and many minerals. In a open pit coal mine, the pit bottom would be the bottom mined coal seam elevation, since it is usually feasible to extract multiple seams when surface mining coal.
Openpit: Reclamation after completion 2. OpenCast: Reclamation during mining 3. Quarries: stone, crushed rock, sand, gravel 4. Strip Mining: removing surface coal in strips up to 50 m wide x 1 Km long 5. Placer Mining 6. Glory hole Mining ISN 10.
Openpit Mining Openpit mining, also known as opencast mining, opencut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit or borrow. The word is used to distinguish this type of mining from
In most areas that they exist, open pit mines are often repeatedlyenlarged to the point that the resource has been exhausted or until the mining process is nolonger economically feasible. Once an openpit mine is closed, there are several scenarios that may occur.
