common types of mining equipment used in the mining industry

common types of mining equipment used in the mining industry

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.

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.

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.

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:

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.

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.

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.

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.

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.

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.

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:

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.

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.

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.

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.

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.

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.

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.

The capital budget you have to invest in buying your equipment with dictate the scale at which you want to mine and influence the long-term operating costs of your mining operation.

Since most of the information online provides lists of gold mining equipment for amateur level mining with equipment like: gold pans, metal detectors, mini sluice box, blue bowl, geologist rock pick, soil scoop, hand screens/classifiers. The items listed just now fall closer to gold prospecting tools and equipment than actual mining.

I will present here what I consider are major equipment lists for 3 types of mining operations. Remember now, a metallurgist is writing. This will not be flawless and since my speciality is process equipment, that is mostly what will be discussed.

Some amateur level gold prospecting equipment such as metal detectors are often classified as mining equipment by small miners/prospectors operating as a hobby. These items include but are not limited to:

5 best bitcoin mining hardware asic machines (2021 rigs)

5 best bitcoin mining hardware asic machines (2021 rigs)

Bitcoin mining is competitive. Its not ideal for the average person to mine since Chinas cheap electricity has allowed it to dominate the mining market. If you want bitcoins then you are better off buying bitcoins.

Originally, Bitcoins creator intended for Bitcoin to be mined on CPUs (your laptop or desktop computer). However, Bitcoin miners discovered they could get more hashing power from graphic cards. Graphic cards were then surpassed by ASICs (Application Specific Integrated Circuits).

Efficiency Youll want to buy the most efficient bitcoin mining hardware possible. Right now, this is the Halong Mining Dragonmint T1. Since miners use a large amount of electricity, you want to buy one that converts the most amount of electricity into bitcoins.

Price How much does the bitcoin miner cost? Cheap mining hardware will mine less bitcoins, which is why efficiency and electricity usage are important. The fastest and more efficient mining hardware is going to cost more.

Don't forget to think about your tax obligation on the coins you buy or mine. There are some great tax software suites to make it easy! For instance, we have a great guide on how that software works to pay taxes on Coinbase buys.

Bitcoin is based on blockchain technology, a decentralized platform which takes power away from a central authority and gives it to the average person. Sensitive information is stored on the blockchain rather than large data centers, and is cryptographically secured. A vast amount of people, known as miners, all work together to validate the network, instead of just one person or government.

In the beginning, CPUs were used to solve cryptographic hash functions, until miners discovered that GPUs were far better equipped for mining. As block difficulty increased, miners turned primarily to GPUs.

With stellar performance comes a high price tag the best ASIC chips will run you a few thousand dollars each. Upon creation, Bitcoin blocks were confirmed by the average person using their desktop once ASICs hit the market, things changed.

ASICs rendered GPUs useless. ASIC developers, including Bitmain, granted early access to large mining cartels rather than the average person. Nowadays, a large majority of Bitcoin mining takes place in China where electricity is cheap.

When ASICs hit the market, the blockchains validation process became more centralized as more and more hashing power was consolidated into a handful of mining companies, rather than being spread out amongst many miners. Unfortunately, Bitcoin is no longer as decentralized as it was once intended to be.

Mining difficulty on the Bitcoin network has been steadily rising at a rate of almost 0.5% per day. Combine that with the fact that the block reward was halved in May 2020, and you can see why theres fierce competition between miners to successfully validate blocks and remain profitable.

As you can see, the S19 is actually a great investment. Youll almost recoup your entire initial investment in under a year - if paying full price for the S19 from Bitmain - and easily mine your way into the black if you get a discount on the hardware when purchasing.

The WhatsMiner M30S+ operates best between -5 and 35 degrees Celsius (23-95 Fahrenheit). This is a wider range than the AntMiner S19 series, and the lower temperatures it can operate at means you may see slightly improved efficiency.

While youll spend nearly $3,600 per year on electricity, the WhatsMiner M30S++s 112 TH/2 will make you a profit of $3,611 per year. This means that youll need to mine for a little under a year to recoup your initial investment.

Despite this, you get more hashing power per dollar invested with MicroBTs WhatsMiner offerings. And AntMiners are incredibly sought-after by the biggest miners in the world, making it hard to get your hands on one.

We have tried to calculate the amount of money that the Chinese have invested in mining, we estimate it to be in the hundreds of millions of dollars. Even with free electricity we cannot see how they will ever get this money back. Either they dont know what they are doing, but that is not very likely at this scale or they have some secret advantage that we dont know about. Sam Cole, KNC CEO
