Open-Pit Mining | Method and Process | Epiroc US

Open-pit mining, also known as opencast mining, is a surface mining technique that extracts minerals from an open pit in the ground. This surface mining technique is used when mineral or ore deposits are found relatively close to the surface.

Open pit machinery can also be used for other purposes such as civil construction, whereas underground mining equipment is specialized and expensive. A number of surface mines operate 24 hours/da y and almost 365 days/year in order to use open pit machinery for as many hours as possible, thereby reducing the number of machines required.

There are two types of benches in each open pit mine: working benches and safety (catch) benches. Working Benches Working benches are where unit operations (drilling, blasting, loading, and hauling) are performed. Working benches are wider than safety benches to provide enough room for the mining equipment to perform their tasks.

Mobile mining equipment at a surface mine can account for up to 30 percent of on-site GHG emissions—or up to 80 percent if the mine doesn't have contiguous smelting or refinery facilities. Large mining haul trucks can represent more than 50 percent of the total surface mobile fleet's GHG emissions.

Open pit mining is the most common mining technology when it comes to new mines. In this technique, the soil is excavated and the mineral separation and the remaining soil material occurs on the surface. The first step in this process is the extraction of the ore (beta with high mineral grade). How does an underground mine work?
