Open-pit mining Wikipedia

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.

Basics of an open pit mine

Open pit mines can be used in coal mining, and they are used extensively in "hard rock" 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. In a

The Mining Process – Waihi Gold

The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers. Dump trucks haul the rock to the primary crushers in the open pit or to

Strip Mining, Open-pit Mining, Surface Mining, Mining

The ore is very near to the surface of the land but has one or more layers of rock and filth on top of it. To mine the ore, these layers have to be removed. The steps in strip mining are similar to open-pit mining. The steps are:

Mining LKAB

Open-pit mining. Ore is extracted from LKAB's surface mines by means of bench mining. The method is based on mining the ore in descending levels through drilling and blasting. The thickness of the slabs, known as the bench height, is 15 metres, and the slabs are worked downwards. Bench mining is an effective and well established mining method

Open Pit Mining an overview | ScienceDirect Topics

Strip mining is the process of mining a seam of mineral by removing a long strip of overlying soil and rock. Strip mining is a practical type of mining when the ore body that is to be extracted is near the surface. Open-pit mining is the process of extracting rock or minerals from the earth through their removal from an open pit or borrow.

Open-Pit Mining Methods
