Types of mining and Components used in and mining

Mining is the activity where we dig deep to uncover precious geological and valuable materials. This search includes metals, gemstones, limestone, clay, and other goodies that Mother Nature has hidden away. Unlike things we can grow on a farm, these treasures can’t be manufactured in a factory or a lab. Mining is the only way to get our hands on these natural wonders. It’s like unlocking the Earth’s secrets, one excavation at a time!

In this blog, Let’s delve more into the world of mining, where we uncover valuable materials by four distinct types of mining:

1. Underground Mining:

This method involves extracting ore from below the Earth’s surface. To access this hidden realm, miners create pathways like horizontal or vertical tunnels, known as adits, shafts, and declines. It’s like opening a door to a mysterious subterranean adventure in search of precious resources!

2. Placer Mining: 

Placer mining is a technique that harnesses the power of water to recover precious metals from deposits like gold-bearing sands and gravel found in slow-moving currents. These deposits typically form when materials settle from fast-flowing streams to more stable waters. The method takes advantage of gold’s high density, causing it to sink faster in moving water. 

One specific form of placer mining is panning. This ancient method involves placing a few handfuls of gold-bearing soil or gravel in a pan with a significant amount of water. Swirling the contents together leads the lighter materials to wash over the side, leaving the gold and gravel behind. Despite its ancient origins, panning remains popular today due to its simplicity and low cost.

3. Surface Mining: 

Surface mining refers to digging up minerals by taking away the dirt and rocks that cover them. This is a popular method since the 1900s, especially in North America. In surface mining, big machines like earthmovers scoop up the stuff on top, and then even bigger machines like bucket wheel excavators or dragline excavators grab the minerals underneath. It’s like peeling back layers to get to the valuable material! 

 There are five different ways in which surface mining is carried out:

1. Open-Pit: 

Open-pit mining is a methodology for extracting minerals or rocks from the Earth by creating an open pit or borrow.

2. Mountaintop mining: 

Mountaintop removal mining, or MTR, coal seams underneath mountaintops are mined. Explosives are used to break up the rock layers above the seam. This in turn removes the mountaintop.

3. Strip Mining:

Strip mining is the most common way to dig up coal and lignite from the surface. It involves taking away a strip of the top layer of soil before getting to the mineral. Strip mining is used when the mineral is pretty close to the surface.

4. Dredging: 

Dredging is a surface mining technique that involves using small dredges to suck up mined material from the bottom of water bodies such as oceans, lakes, and rivers.

4. In-situ Mining: 

In-situ mining is a way of mining to get minerals like uranium and copper by drilling holes into a deposit. Instead of digging up the minerals, in-situ mining dissolves them in the ground. A special solution is pumped into the holes to dissolve the minerals, and then it’s brought back up to the surface to be processed. This method lets us get salts and metals from the ground without digging tunnels or using traditional mining.

Mining Components:

  • Mining Pumps: 

It’s important to handle excess water properly when getting minerals from below the ground. If there’s too much water or flooding, it can limit how deep we can work in the mine. To avoid this, we use pumps to manage the water and keep the mining process safe and effective.

  • Draglines: 

Draglines resemble mining excavators featuring a boom supported by a network of ropes and cables, with a bucket attached. The process involves lowering the bucket to collect overburden or mined material by scraping it along the ground.

  • Dozers: 

Dozers, an important mining equipment, are primarily essential for surface mining rather than subsurface mining techniques. With the incorporation of essential attachments, dozers can be employed for a diverse range of tasks.

  • Doubled Wall Pumps:

These pumps feature two layers or walls for added durability, insulation, or to prevent leakage. This type of pump is often used in applications where safety and containment of the pumped fluid are crucial, such as handling hazardous or corrosive substances.

  • Mining Drill Rigs: 

A mining drill rig holds significant importance in the mining activity. It is employed to bore holes in rock or soil for the placement of explosive charges, facilitating the blasting of open-pit mines. Another alternative is percussion drills, commonly known as hammer drills. In rotary mining machines, the drill bits spin under pressure while cutting through rock. 

There are many more components that are used in mining. The requirements of these mining components change as per the type of mining.

Conclusion: 

Given the integral role mining plays in modern life, it’s unsurprising that the production of mining equipment is a booming industry. This sector offers a plethora of equipment catering to both subsurface and surface mining methods.

Your only task is to select the most suitable equipment for your needs from reputable mining equipment manufacturers. While larger vehicles have their advantages, there are instances where smaller mining equipment proves to be more practical.
