What Equipment is Needed for Mining?

Kexin Product Page

Mining equipment has been modernized over the last few years, and mining companies must be careful to purchase the right gear and parts for each job. Drillers and excavators are still needed to get the work done, but companies also need hand tools that work in the lowest parts of a mine, the parts to maintain these machines, and the extras that are required to keep the miners safe. Look below at what you need to do to buy the right mining equipment so that your operation runs smoothly.

1. Earth Movers

Earth movers are a large part of the mining world because they can move large mounds of dirt and wealth very quickly. These might be considered bulldozers in some cases, but there are other times when you need to use a backhoe because that is much more efficient. Earth movers might be small bulldozers that fit into tiny spaces, and they might be large bulldozers that can level a large area in a short period of time.

These earth movers are complex machines that have many interior parts. You must look for the right parts to repair and maintain your machines so that you can get the most out of your investment. Someone who is running many earth movers every day will find that getting parts is a large part of the job. These parts must be kept around so that they can be installed in your machines with no trouble.

2. Blasting Tools

Blasting tools are not just the dynamite or explosives that are used for mining. You need to be sure that you habve found blasting tools that help you do a remote detonation, help you remain safe, and help you arm the system only when you are far away from the blasting area. You need to get special signal jammers that will prevent cell phones and radios from setting off your explosives while you are working on the job. You must collect all these tools, keep them in a safe place, and make certain that they are in good working order. Replacing some of these smaller blasting tools is very easy to do in most cases.

3. Conveyors

Conveyors are needed to move things out of the mine and onto level ground. he conveyor is usually a large belt that can take rocks and stones up from the deep parts of the mine to a place where they can be carted away. Some conveyors are meant to come all the way out of the mine, but other conveyors are meant to bring your debris only part of the way up the mine so that it can be removed or used for shoring up the shafts of the mine.

4. Trucks

Trucks are needed because you must have a way of driving off with your materials to be dumped in another location. Someone who is trying to keep their company efficient will need a fleet of trucks that they can use to move their debris from one place to another. This is important because you do not want to work on a rental basis with a company that might not be able to fulfill your needs. You also need to be sure that you have common repair parts for the truck so that you never need to wait for a technician to come look at the truck. Many of your repairs can be done on-site.

5. Hand Tools

Hand tools should be purchased for everyone who wants to be in the mine. Your staff is down there making sure that they can clean up the area, knock away rocks, and do so without using explosives or heavy machines. There are larger drillers that come down into the mine to start the job, but hand tools are often used because they can refine the mine in a way that makes it much safer. Plus, the miners can shore up the mine by making spaces to use the boards and rocks that are needed to keep the mine stable.

6. Conclusion

The mining tools that you buy are quite diverse because you are doing so much work inside a mine. You need something that helps you dig in the mine, helps you remove rubble, and helps you take that rubble out of the job site. You need trucks, and you need the parts that will keep those trucks running. You also need to find parts for all your machines so that you can keep them operational even during a breakdown.

Mining is one of the most vital components of modern society due to the use of mined minerals in almost every consumer product. Additionally, 50% of the nation&#;s energy comes from coal or nuclear power that uses uranium. To support this need for modern equipment, mines are found in all 50 states, including our home state of Nevada.

Mining in Nevada

Nevada&#;s mining industry is the biggest export sector in the state. Precious minerals such as gold, copper, and silver are well-known materials mined. However, the state also extracts many other goods from the earth, including minerals used for both construction work and consumer goods.

Products mined for construction work include gravel, sand, gypsum, and limestone. These goods contribute to the building sites for erecting structures and infrastructure components required for modern living.

Consumers also directly benefit from Nevada mining operations. Minerals such as iron, molybdenum, and lithium are integral components to cars, computers, electronics, and other innovations used in daily life. Gold, copper, and silver also appear in electronics and fine jewelry.

Even energy can come from mining. With Nevada&#;s rich sources of geothermal energy, mining can extract heat from the earth to help create power.

Because the mining industry is so critical to modern life, manufacturing mining equipment is a booming business, too. This industry offers numerous types of heavy equipment for mining to meet the specific needs of either underground or surface operations.

Types of Mining and Their Respective Equipment

Mining can happen at the surface or underground. The environment and type of material mined dictate the form of mining required and the equipment used. Both surface and underground mining have three main steps:

1. Extraction: This involves drilling, blasting, or digging to remove materials from the mine site.
2. Material handling: This includes sorting and loading materials to either go to a waste area or the processing site.
3. Material processing: The final step involves grinding, separating, crushing, refining, and smelting mined ore or other goods at an off-site plant to turn them into finished products.

Surface Mining

Surface mining includes numerous techniques and is the most common method for non-fuel minerals, producing 97% of the amount mined. Miners choose surface extraction for minerals located close to the surface.

There are three main ways to mine on the surface. These methods include quarrying, open-pit mining, and strip mining.

In quarrying, miners may cut blocks of hard stone for ornamental purposes, such as granite for building. However, quarrying can also refer to extracting gravel, crushed stone, and sand using similar techniques to open-pit mining.

Open-pit mining requires creating a large pit in the ground from which the miners extract the needed material. This is one method miners may use to extract silver from the earth. The other technique is underground silver mining. Occasionally, removing a hilltop with explosives to expose the rocky materials beneath is the first step in creating an open pit. Rotary drills create the holes used for inserting the explosives for this process.

The third type of surface mining is strip mining, which primarily extracts thin layers of coal from near the surface. Since coal is not a major mining product of Nevada, the inclusion of strip mining here serves only to round out the three types of surface mining used around the world.

This form of mining starts with removing large strips of surface material, known as overburden. The first strips of overburden go outside the mine site. After extracting mined products from the initial strip, the newly created hole will hold the deposits of future strips of overburden removed from the mine. For hilly sites, contour strip mining requires using shovels or dozers to remove strips of overburden around the hill in terraces. For flat surfaces, area strip mining using equipment such as draglines or scrapers will suffice.

Underground Mining

Minerals, ore, metals, or other goods located deep underground require different techniques for their removal. Mining may involve hard or soft rock, each of which requires specific tools to extract the materials. For instance, the tools used to dig soft materials might not provide enough power for cutting through hard rock.

Uses of mining equipment for underground mining include automating processes and using no-emission vehicles to preserve miners&#; safety.

Types of underground mining include the following:

• Room and pillar mining: Miners create pillars of ore to support the ceiling as they dig out the rest of the desired material from the space. This system may also use a continuous mining system for extracting material instead of personnel.
• Retreat mining: This type follows room and pillar mining until mining completes in the room. This method removes the pillars for their ore content to maximize material recovery.
• Blast mining: Blast mining uses explosives to loosen rocks and open mining spaces, especially to remove hard rock from both underground or surface mines.

10 Types of Heavy Equipment Used in Mining

To understand the available options you have for machinery, here is a list of mining equipment used for surface or underground mining operations, plus their uses:

1. Large Mining Trucks

To move materials around a mine site, workers need heavy-duty trucks. Also known as off-highway trucks, large mining trucks include both powerful mechanical models and environmentally friendly electric drive models.

Unlike conventional trucks, these mining vehicles have extra-large tires to support the heavy loads over uneven terrain commonly found around surface mines.

Additionally, these trucks can carry high payload capacities to accommodate the need for moving weighty mined minerals or ore out of the site. Large mining trucks also need to perform in the most extreme conditions &#; cold, heat, heavy dust, high altitudes, and steep slopes while hauling heavy loads.

Common applications of these off-highway vehicles include:

• Moving materials at surface mines.
• Hauling materials up steep slopes.
• Carrying up to a 400-ton payload.

2. Hydraulic Mining Shovels

Sometimes called excavators, mining shovels used today grew out of the original steam shovel design used in years past. The models used now often employ hydraulics for moving the shovel to power through tough materials.

Overall, hydraulic mining shovels have similarities in their designs. Most have a base with either tracks or wheels atop which the pivoting cab sits. The pivoting action allows the operator to access material in a circle around the shovel without moving significantly. An articulated arm holds the shovel, both of which the operator controls from inside the cab.

Applications for hydraulic mining shovels include:

• Moving earth or mined materials.
• Digging.
• Scooping material into a loader.
• Removing rock or dirt, also known as overburden, from surface mines to open the site.
• Transporting some mined materials.

3. Large Dozers

Large mining dozers move materials easily around a mining site. Plus, the choice of vehicles with wheels or tracks increases the types of surfaces these dozers can operate on. Additional attachments can change the dozers&#; uses to include the following applications:

• Building mine sites by pushing the surface material away to expose the ground beneath.
• Maintaining a mine site by pushing dirt away from working areas.
• Reclaiming the land around mining sites.
• Ripping plant matter out of the ground.
• Raking the land around a mine site.

4. Electric Rope Shovels

Instead of using hydraulics to control the movement of the shovel at the end of the arm, electric rope shovels use a series of pulleys and ropes. Unlike hydraulic shovels, these models use electric operation, allowing for highly efficient performance over time.

Uses of electric rope shovels mimic those of hydraulic excavators. Therefore, rope shovels have the following applications:

• Removing overburden to prepare a mine site.
• Digging through hard materials.
• Moving earth.
• Removing boulders.
• Transferring mined material to a loader.
• Transporting material.

5. Rotary Drill Rigs and Rock Drills

Rotary drill rigs create holes through rock or soil, allowing placement of charges for blasting open mines. A rotary drill rig is one of two main types of drills used for mining. The other type is a percussion or hammer drill. For a rotary drill rig, the drill bit turns under pressure to cut into the rock. As the bit turns, the rock grinds down while compressed air sends it back up the drill to the top to keep the hole and bit clean.

Ideally, rotary drill bits create holes that range from 6 to 22 inches in diameter and average 30 to 60 feet deep. In some cases, though, miners will use rotary drills to dig holes up to 150 feet deep and as shallow as 15 feet.

For hammer rock drills, pressure forcefully shoves the bit into the ground to create a hole. To keep the hole clean, compressed air blows dirt out of the way to allow the bit to always strike new ground. Hammer drills with the piston located outside the hole (OTH) typically drill smaller holes of 5 inches or fewer in diameter.

Rotary and rock drills have the following uses:

• Creating holes for blasting charges for surface mining.
• Production drilling to make wells.
• Presplit rock drilling.
• Expanding mines.

6. Motor Graders

Mines rarely have ready access to roads. Even those near major roadways still need roads built within the area for moving material and hauling mined goods out. Motor graders are used for surface operations around mines to create and maintain these roads.

When hauling minerals, ore, or other mined materials along roads, things like debris or ponding water can slow vehicles. Motor graders ensure the roads have the necessary grading and adequate drainage. By maintaining the integrity of roads used for transporting the material around and out of the mining area, motor graders play a vital role in ensuring the efficiency of the mine&#;s operations.

Common uses for graders include:

• Pushing surface material to clear roads.
• Creating proper grades to allow water to drain away from roads.
• Constructing haul roads.

7. Large Wheel Loaders

For picking up and quickly moving material across a mining site for loading into trucks, nothing matches the versatility of large wheel loaders. Sizes vary from compact to large. As the wheel loader&#;s size increases, its bucket capacity and load handling also go up. Matching the wheel loader&#;s handling capabilities for both volume and density of materials at the mine is crucial to ensure the machine will hold up to the rigors of daily use without premature wear.

For Cat® wheel loaders, the compact models work best with light materials and have a bucket capacity of 2 cubic yards. However, large models can handle iron ore or rock and can hold up to 38 cubic yards of rock in the bucket. You will have a varied selection of wheel loaders to fit in the space around your surface mine and handle the loads you need to move.

Typically found at surface mines, large wheel loaders can take on many tasks, such as:

• Loading materials onto trucks for transport.
• Digging.
• Supporting jobs of other loading and transport vehicles on-site.

8. Draglines

Draglines are large excavators with a bucket supported by ropes and wires at the end of a boom. Lowering the bucket and scraping it along the ground collects overburden or mined material. Swinging the bucket at the end of the dragline around repositions it to dump its contents into a specified location.

Surface mining heavily uses draglines. These excavators have numerous functions, including:

• Moving tons of overburden to prepare a surface mine.
• Removing exposed material, such as tar sand, from a strip mine.
• Reducing emissions compared to other overburden removal methods.
• Cutting into high wall surfaces and removing material.

9. Wheel Tractor Scrapers

Wheel tractor scrapers have a design similar to motor graders. However, the scrapers typically have an attached bin that collects the material removed from the ground&#;s surface rather than pushing it to the side as a grader does.

To operate the scraper, the driver uses controls inside the cab to raise or lower the bin to the ground. When on the ground, the edge of the bin scrapes the ground materials, which feed directly into the bin. When filled, a vertical flap holds the material inside the bin, so it does not spill during transport. At the deposit location, the bin tilts and opens in the rear to empty the scraped dirt.

Applications for scrapers include:

• Building roads.
• Making initial cuts into the land for a mine.
• Reclaiming land.
• Performing mining operations.

10. Underground Mining Loaders and Trucks

Underground mining trucks and loaders require specific operating parameters to function in confined spaces. Additionally, these vehicles cannot produce emissions in the enclosed environment of a mine. Therefore, standard trucks used for surface mining will not suffice for underground work.

Mining trucks and loaders for underground operations have specially built engines that do not produce emissions but still have enough power to move tons of rock.

For these machines, their uses include:

• Digging.
• Loading rock or mined material into trucks.
• Transporting material to the surface.
