Open Pit Mining. Open-pit mining, also known as opencast mining, open-cut 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 extractive methods that need tunneling into the earth.

Open-pit mining technology. Open-pit mining clearly offers a number of economic advantages over underground mining, especially now that mineral-processing technology has advanced to the stage where very low-grade ores can be treated profitably. 100 to 150 years ago, this was not the case, and mining was still much more selective.
Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. Open-pit mining is the most common method used throughout the world for mineral mining and does not require extractive methods or tunnels. This surface mining technique is used whe…See more on angloamerican

To quantitatively understand the failure process and failure mechanism of a rock mass during the transformation from open-pit mining to underground mining, the Shirengou Iron Mine was selected as an engineering project case study. The study area was determined using the rock mass basic quality classification method and the …
Open-pit mining is commonly used to extract metallic ores like aluminum, bauxite, copper, gold, copper, and iron as well as non-metallic ores like coal, uranium, and phosphate. Open-pit mining is ...
Open pit mining. This method of mining is mainly used for hard rock gold, iron sand, aggregate or coal mining in New Zealand.

Open Cast Mining. Open cast mining is usually associated with coal or other tabular deposits that are more or less flat-lying. A significant difference between open pit and open cast mining methods is that in open cast mining, overburden that is removed to gain access to the ore is immediately placed in the previously mined cut.
