Sishen Mine, Northern Cape, South Africa
Mining and processing of iron ore. The Sishen mine employs the open-pit mining method involving drill and blast. The mined ore is trucked to the nearby beneficiation plant. The mine uses a fleet of P101-4100 shovels and 960 trucks. Strong performance of the 2,800 shovel fleet in 2019 allowed the mine to exceed equipment …

6 Common Blasting Methods in Open Pit Mining
We know that open-pit mining operations mainly include drilling, blasting, mining, transportation and dumping. Blasting is a very important part of it. Blasting costs account for 15% to 20% of the total cost of open pit mining. ... Cracks often occur at the top of steps, and the stability of the step surface is relatively poor. Inclined drilling.

Open-pit Mining
Open-pit mining occurs on surface and is generally the cheapest way to extract ore. This is because rock doesn't have to be moved far up hill against gravity, equipment used can be larger than underground, and it doesn't require more expensive features like ventilation, communications, etc. that underground does.

Open-Pit Mining
Open-pit mining is a surface-mining operation, in which rocks or minerals are extracted from the Earth by creating an open hole, or pit, in the Earth's surface. These pits are generally 1km deep beneath the Earth's surface, and are used to exploit low-grade ore bodies. This type of mining is used only when the minerals to be extracted are ...

4.1.1 Iron Ore Mining There are two basic methods of mining iron ore. These are: • Surface mining or open-pit mining • Underground or shaft mining To be competitive, iron mining must be done on a very large scale. Surface mining is the preferred choice, although there are exceptions. Small, low-capacity mines have rapidly disappeared.
