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 coal.

However, the first step is to loosen the rock in the ore body so that it can be moved and processed. Blasting and grinding equipment are used to accomplish this task. Open pit mining is a technique used to extract copper ore near the earth's surface. Open pit mining is the most widely used technique of mining copper today.
Open-pit mining which is sometimes referred to as open cut mining, opencast mining or simply strip mining is a mining technique that extracts important minerals from a borrow or an open pit. There are two types of mining methods commonly used in large scale mineral mining; open pit mining …
Open-pit Mining Open-pit mining, also known as opencast mining, open-cut mining, and strip mining, means a process of digging out rock or minerals from the earth by their elimination from an open pit …
Anoush specializes in strategic mine planning, mine evaluation, open pit optimization and design, production scheduling, mine layout optimization, mine simulation, and computer modelling. He is an adjunct professor at the University of British Columbia and a director of the CIM's Vancouver branch.
open pit, open cast or open cut mining is a surface mining technique of extracting rock or minerals from the earth by their removal from an open pit or borrow.. this form of mining differs from extractive methods that require tunneling into the earth, such as long wall mining.
Open pit mines may be circular, like the ones shown pictured at the Ekati mine, or oblong, and include several mining levels know as benches. Roads, known as ramps, allow access to the orebody. The size and depth of an open pit is a balance of how much worthless waste rock must be mined to gain access to the valuable ore.

Mar 13, 2018· Open pit mining is the preferred method for mining gold, silver, and uranium. This type of mining is also used to dig for coal and building stone.
Mining, the extracting of ore, can be broken down into a three step process with diamonds. The first step is to extract the ore and two different practices are common in North America. In Colorado at the State Line Kimberlite District, open pit mining is the best choice for extracting the kimberlite ore.
Open-pit mining is one of the most commonly used techniques to extract minerals from the Earth. The process, which is also known as "opencast mining," "open-cut mining" and "strip mining," is used when deposits are located close to the surface, and entails digging or …
Techniques of surface mining include: open-pit mining, which is the recovery of materials from an open pit in the ground, quarrying, identical to open-pit mining except that it refers to sand, stone and clay; strip mining, which consists of stripping surface layers off to reveal ore/seams underneath; and mountaintop removal, commonly associated ...
The Advantages of Open Pit Mining
Open Pit Mining Process Opencast sometimes referred to as open cut mining, surface mining or simply open pit is extracted a mining technique that important minerals from a borrow or an open pit. There are two types of extraction methods, commonly used in Large scale mining mineral; Open pit mining and tunnel mining or Under ground mining.
Mar 14, 2014· Areas for open pit mining are selected using the mining plan. Identified areas are then tagged. The ore is mined from large open pits by progressive extraction along steps or benches.
The Mining Process. The Mining Process. 1. Mining – open pit and underground. To define the ore from the waste rock, samples are taken and assayed. Assay results are used to mark out areas of ore and waste rock, which are mined separately. Some of the harder areas require blasting to loosen the rock prior to excavation by hydraulic diggers.
The steps in strip mining are similar to open-pit mining. The steps are: The trees and bushes are pushed down through bulldozers. This waste, along with the filth or sand under it, is taken to a close area and dumped. Lots of minute holes are drilled from the rock that is above the coal or mineral bed [vein] ...

Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.
