Since nearly half of the open pit surface mines in the U.S. produce sand and gravel (aggregate), lots of questions tend to come up about the equipment used in that type of mining. As you can imagine, it takes a range of both mobile and stationary equipment to run a sand and gravel operation.
Surface mining, also called strip mining, delivers economically vital supplies of coal, which powers transportation and creates consumer products, boosting local economies. This type of mining occurs primarily on mountaintops, and dates back to the early 20th century when new machines made moving earth easier.
Types of surface mining. With technological advancements, becoming a miner has taken on a whole new meaning. You might be surprised by how many types of surface mining there are and how many career paths are available in the industry. However, mining companies don't use all methods equally.
Blocks. Yet another important tool in the surface mining process is the block system. Many block systems rely on a welded-in construction that requires up to an hour and a half to change, but some manufacturers offer blocks that rely on modular construction instead — allowing for changes that can be made in as little as 15 minutes.
The three main types of surface coal mining are strip mining, open-pit mining, and mountaintop removal (MTR) mining. Surface Mining: Strip Mining Strip mining is used where coal seams are located very near the surface and can be removed in massive layers, or strips. Overburden is usually removed with explosives and towed …

4. Strip mining. Strip mining is the process of eliminating overburden above a seam or layer of material, such as coal, and then mining the exposed matter. A common type of strip mining is called contour mining. Contour mining removes the overburden layer from hilly terrain where the seam is roughly the same height along the hillside.
This type of mining uses state-of-the-art technology to produce minerals, the only difference with medium and large mining is the volume and size of the deposit. Artisanal mining Many think that this type of mining does not use state-of-the-art technology, however, on the contrary, they must use the same technology as large-scale …

Learn about four common types of mining: surface, underground, placer, and in-situ. Each type has advantages and disadvantages depending on the material, location, and equipment used.
Different mining sites require their own unique sets of equipment. While the majority of this post will focus on surface mining equipment, it's essential to explain the differences between the two main mining types. Above ground, or surface mining, includes strip mining, open-pit mining, and mountaintop removal mining.
Mining techniques. Surface mining. Surface mining is done by removing (stripping) surface vegetation, dirt, and, if necessary, layers of bedrock in order to reach buried ore deposits. 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 …
1. Surface mining Surface mining is the most common method used to extract minerals and ores that are located close to the surface of the earth. It involves the removal of overlying soil and rock, thereby facilitating access to the mineral deposits. Surface mining can be further sub-divided into strip mining, open-pit mining, and …
Learn about the different types of surface mining, such as open-pit, dredging, strip and mountaintop removal, and how they are used to extract various minerals. Find out the steps involved in the surface …
The type of underground mining technique used is typically based on the geology of the area, especially the amount of ground support needed to make mining safe. Surface Mining. Surface mining involves removal of plant life, soil and potentially bedrock to be able to access resource deposits. It is normally used for fairly shallow, non …
This process is called surface mining; because contact is maintained with the surface throughout. The other harder method is to drill holes deep inside the Earth to travel beneath the rock layer. As expected, this …
Understand how surface mining works with a detailed review of the 4 main steps in processing stone, sand, and gravel. ... Often referred to as the "prospecting" stage of mining, this type of dedicated and professional exploration involves detailed geologic surveys and testing. The purpose of prospecting is to assess the economic value of a ...
Learn about the four main methods of mining: underground, open surface, placer, and in-situ. Find out how each method depends on the type, location, and value of the mineral resource and its environmental impact.
Surface mining is a method of extracting minerals and resources from the Earth's surface. It is a highly efficient and cost-effective method of mining that has become increasingly popular in recent years. There are five main types of surface mining: strip mining, open-pit mining, mountaintop removal, dredging, and highwall mining.
UN – EOLSS SAMPLE CHAPTERS CIVIL ENGINEERING – Vol. II - Surface Mining Methods and Equipment - J. Yamatomi and S. Okubo ©Encyclopedia of Life Support Systems (EOLSS) Figure 2. Change in production and productivity of US coal mines The higher productivity for open pit mining equipment also lowers costs.
There are four main mining methods: underground, open surface (pit), placer, and in-situ mining. Underground mines are more expensive and are often used to reach deeper deposits. Surface mines are typically used for more shallow and less valuable deposits. Placer mining is used to sift out valuable metals from sediments in river channels, …

For surface-type surface mining, it remains essentially the same during the entire working period. For deep, on-slope and combined-type mining, the ultimate depth is established at the stage of quarry design. The ultimate depth of modern quarries or pits measures from a few meters up to 450 m. Projects envisage the possibility of surface …
Mining - Underground, Safety, Techniques: When any ore body lies a considerable distance below the surface, the amount of waste that has to be removed in order to uncover the ore through surface mining becomes prohibitive, and underground techniques must be considered. Counting against underground mining are the costs, …
Types of Surface Mining There are three common surface mining methods. Strip mining. Strip mining is the activity of removing a layer of earth to access the minerals that are in shallow deposits and continuing to do the same in adjacent areas without digging deeper vertically.
