Is underground mining better than open pit?
Underground mining Underground mining is practical when: The ore body is too deep to mine profitably by open pit. The grades or quality of the orebody are high enough to cover costs. Underground mining has a lower ground footprint than open pit mining.
What is the difference between open pit mining and quarrying?
A quarry is the same thing as an open-pit mine from which minerals are extracted. The only trivial difference between the two is that open-pit mines that produce building materials and dimension stone are commonly referred to as quarries.
What is the main difference between open cast and open pit mining?
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.
What is difference between an open pit mine a quarry and underground mine with shafts?
Open-pit mines are used when deposits of commercially useful ore or rocks are found near the surface. In contrast, minerals that have been found underground but are difficult to retrieve due to hard rock, can be reached using a form of underground mining.
What are the types of underground mining?
4.3. 2: Underground Mining Methods
- Room and Pillar mining. This method of mining is used to recover bedded deposits that are horizontal or nearly horizontal when the orebody and the surrounding rock are reasonably competent.
- Shrinkage stoping.
- Cut and fill.
- Block caving.
- Sublevel caving.
- Longwall mining.
What is the difference between open pit mine a quarry and underground mine with shafts?
Why most open pit mining is converted into underground mining?
This transition from open-pit to underground begins when open-pit mines are exhausted or inaccessible; meaning, they have either been depleted of minerals, rocks, and resources, or they are unfeasible to build upon.
What is open pit mining Class 10?
Open Pit Mine. Quarry. Underground Mine with Shafts. Minerals are removed from a pot dug in the ground. Minerals are removed from a shallow pit dug in the ground.
How do you 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 are the types of mining methods?
Block Caving. Block caving is a general term and usually has to do with a mass-mining system that relies on gravity to extract the ore deposits.
