Mar 12, 2018· It demonstrates how, by using strategic mine planning techniques, it's possible to uncover the opportunities and risks within the different stages of developing a mining project. Open pit mine design techniques are introduced and the Lerchs-Grossmann (LG) pit optimization algorithm is .
Conventional Methods of Surface Mining. Open-pit mining and strip mining are the two major categories of surface mining which account for more than 90% worldwide surface mining production. The primary differences between these mining methods are the location of the ore body and the mode of mechanical extraction.
Open-pit mining or opencast mining refers to a method of extracting rock or minerals from the earth by their removal from an open pit or borrow. It is a form of surface mining. The term is used to differentiate this form of mining from extractive methods that require tunneling into the earth, like longwall mining.
Mar 02, 2016· 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 and tunneling.
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.

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.
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.

Open-pit mining causes changes to vegetation, soil, and bedrock, which ultimately contributes to changes in surface hydrology, groundwater levels, and flow paths. Additionally, open-pit produces harmful pollutants depending on the type of mineral being mined, and the type of mining .
Strip mining, removal of soil and rock (overburden) above a layer or seam (particularly coal), followed by the removal of the exposed mineral. The common strip-mining techniques are classified as area mining or contour mining on the basis of the deposit geometry and type. The cycle of operations for ...
Nov 14, 2014· A three phased mine planning process can be employed to avoid this tactical planning pain in an open cut mine. The three phases of mine planning ensure that the highest value is received from an open cut mine based on a practical schedule, which is implemented in a shorter planning horizon. Phase 1: Practical NPV Schedules
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.
