Open Cut and Underground Mining iMINCO

Underground Mining is generally used for areas where the mineral seam is too far underground for open cut mining to be of use. A tunnel, called a decline, is created to allow workers and machinery to reach the location of the minerals. Stope mining is used for most hard rock mining of minerals such as copper, silver, lead and zinc.

Basics of an open pit mine

The planning of an open pit mine is, therefore, basically an exercise in economics, constrained by certain geologic and mining engineering aspects. A bench may be defined as a ledge that forms a single level of operation above which mineral or waste materials are mined back to a bench face.

List of Equipment Used in Opencast Coal Mining Mining

Opencast mining is the oldest method of excavating minerals but the mining operations have been mechanised by the use of heavy earth moving machinery during the last 50 years resulting in excavations on a scale which was unthinkable half a century ago. Equipment 1. Bulldozer

(BWEs). These machines excavate and deposit material in one continuous operation. The same function can be accomplished, in part, through the use of explosives (cast blasting). Often removal of soil and overburden is accomplished using a combination of casting machines to maximize the width of the mining

OpenPit Mining Methods

Openpit mining methods are applicable to mining ore deposits that apex at or near the surface. If the deposit apexes below the surface, the overburden and barren capping overlying the ore must be removed in advance of openpit mining. The removal of this material is known as stripping.

Openpit mining

Extraction

Openpit, opencast 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 tunnelling into the earth, such as long wall mining. Openpit mines are used when deposits of commercially useful ore or rocks are found near the surface. It is applied to ore or rocks found at the surface because the overburdenis relatively thin or the

Coal mining Facts for Kids Kiddle encyclopedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content, and, since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production.

Exposure to wholebody vibration in opencast mines in the

Occupational exposure to wholebody vibration (WBV) originating from the operation of vehicles has long been acknowledged to be a significant risk for low back pain for vehicle drivers ().Operators of vehicles used in opencast mining are exposed to significant WBV for relatively long periods (27).Studies have also indicated that the prevalence of selfreported musculoskeletal pain is

How Are Diamonds Mined And Extracted From the Ground

Because marine deposits are distributed over large areas unevenly, mining companies utilize different methods to mine them. Some of these methods include shallowwater mining, deep sea operations involving high tech equipment and simple alluvial mining. Like open pit mining, the ore materials are usually transported offsite for further processing.

What Are the Different Types of Mining? Reference

Mining is further divided into several other categories including room and pillar mining, slope mining, block caving, quarrying, openpit mining and in situ mining. Surface mining involves stripping surface vegetation, dirt, bedrock and other layers of the earth to reach ore deposits underneath.

Surface Mining Methods and Equipment

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.
