What does open cut mean in mining?

Open Cut. Open cut (or open pit) mining involves digging and/or drilling and blasting to remove the resource or ore for processing. Often there is ‘overburden’ or waste rock material, which must be removed before the actual resource can be mined.

What is an example of open cut mining?

Materials commonly extracted from open-pit mines include: Coal. Copper. Coquina. Diamonds.

What is the opening of a mine called?

An adit (from Latin aditus, entrance) is an entrance to an underground mine which is horizontal or nearly horizontal, by which the mine can be entered, drained of water, ventilated, and minerals extracted at the lowest convenient level. Adits are also used to explore for mineral veins.

What are the 4 stages of a mining operation?

The mining industry operates through a sequence of stages: exploration, discovery, development, production and reclamation.

How do you start an open pit mine?

To create an open-pit mine, the miners must determine the information of the ore that is underground. This is done through drilling of probe holes in the ground, then plotting each hole location on a map. The information gained through the holes with provide an idea of the vertical extent of the ore’s body.

What is a miners spot called?

quarry. noun. a place where stone is dug out of the ground. A place where coal or minerals are dug out of the ground is called a mine.

What are the basic stages of mine?

There are five stages of the mining life cycle, these include: exploration, mine-site design and planning, construction, production, and closure and reclamation.

What are the steps of open-pit mining?

The open-pit mining cycle includes drilling ore and waste rock, loading drill holes with explosives, blasting, ore loading and hauling to stockpiles for processing, waste rock loading and hauling to the waste rock storage pile.

What are the cons for open pit mining?

Efficient Operations. One of the major benefits to open pit mining is the increase in efficiency over deep-shaft mining techniques.

  • Greater Safety. Open-pit mining is much safer than shaft mining.
  • Loss of Ecosystem. An open pit mining operation virtually eliminates any biologic life at the surface.
  • Pollution and Drainage.
  • What are the effects of open pit mining?

    Open-pit mining is to be considered one of the most dangerous sectors in the industrial world. It causes significant effects to miners health, as well as damage to the ecological land. Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths.

    What is the process of 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.

    What are the environmental impacts of open pit mining?

    Open-pit mining is the primary extraction method in Chile (used in up to 91% of the mines) [1] involving explosive procedures and heavy machinery. Environmental impacts of open-pit mining include erosion, biodiversity loss, as well as contamination of the groundwater and pollution of ambient air [2,3].
