Advantages and disadvantages of open pit mining –

Open pit mines are those mining operations that take place on the surface, unlike the underground mines. This is possible when the reservoir sprouts on the surface or at a very small depth. It began to be realized in the middle of the XVI century and it is used all over the world.Get price

AMIT 129: Lesson 2 Open Pit and PPE

Open-Pit Mining Open pit mining is the process of mining any near-surface deposits by means of a surface pit excavated using one or more horizontal benches. Open pit mines are often used in mining metallic or nonmetallic deposits and more sparingly in coal and other bedded deposits.Get price

Open Pit Mining

2019/10/8Open pit mining method is one of the surface mining methods that has a traditional cone-shaped excavation and is usually employed to exploit a near-surface, nonselective and low-grade zones deposits. It often results in high productivity and requires large capital investments, low operating costs, and good safety conditions. The main topics that will be discussed in this chapter will include Get price

Surface mining

Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral is removed through shafts or tunnels.Get price

Safety in Open Pit Mining

From what we learned so far, we can say that mining is a very high risk business, from both the safety and economic point of view. Slope stability is one of the major sources of risk, and hazards arise in several ways, from an incomplete knowledge of geological conditions, and an incomplete knowledge of damage caused by mining Get price

Highwall Safety

In these particular projects, otherwise known as open-pit mining, employs a technique in which rock and minerals are extracted from a borrow pit, or sandbox. For long-term highwall performance, the substance properties that makeup mining sites—or more specifically, the rocks and minerals found within the borrow—should be carefully examined, and the overall highwall safety considered.Get price

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 Get price
