A Brief Introduction to the Types of Surface Mining Methods

In the manufacturing sector, industries need a continuous supply of certain raw materials like iron, aluminum, and coal. Such materials are found in nature, though in an impure form called 'minerals'. These minerals do not occur by themselves, but are trapped in rocks called 'ores'. To make matters worse, ores are found.

Strip Mining, Open-pit Mining, Surface Mining, Mining Techniques .

Mining · Mining Techniques; Strip Mining. Strip Mining. Strip mining is a kind of surface mining. The ore is very near to the surface of the land but has one or more layers of rock and filth on top of it. To mine the ore, these layers have to be removed. The steps in strip mining are similar to open-pit mining. The steps are:.

Mining Technology

acteristic of the Midwest and the East. Surface Mining Techniques. Surface mining of coal is characterized by the use of large, capital-intensive and effi- cient mining equipment. First, the overlying soil and rock layers (overburden) are re- moved. The coal is then fractured with explo- sives or machines, and loaded onto vehi-.

Open-Pit Mining Methods - 911 Metallurgist

Apr 11, 2017 . The question of whether to mine by open-pit or underground methods is an economic one. The economic limit for open-pit mining is reached when the preparatory and stripping costs per ton of ore plus the open-pit mining cost per ton of ore plus the cost of equipment, interest, and amortization charges.
