Mining Tools in 2022—A Guide to Mining Equipment and Mining Machines

Mining tools is a general phrase that refers to all the mining equipment and mining machines used to extract minerals from the earth.

Mined minerals appear in almost every consumer product—from cars, to electronics, to jewelry and more. Minerals like uranium and coal are major energy sources that account for 50% of the US’s energy supply.

All of these resources are obtained through the use of various types of mining tools and mining equipment.

Before we begin identifying key mining tools and mining machines, it’s important to understand the different types of mining methods for which these tools are used.

Toward that end, the first section of this guide covers the different mining techniques and methods. After we provide that context for the different ways mining is done we'll dive into the specific tools used for each type of mining.

Types of Mining Methods 

Mining falls into two categories: surface mining and underground mining.

The type of minerals that a mining operation is trying to extract and the mining techniques they're using to extract those minerals directly informs the types of tools that miners use in their work.

That being said, a basic method is always followed for both surface and underground mining. That method is:

  1. Extraction. Extraction consists of digging, drilling, or blasting into the earth to extract minerals.
  2. Material handling. Material handling consists of sorting through materials, sending target minerals to a processing site, and sending irrelevant materials to a waste area.
  3. Material processing. Material processing is where minerals go to be smelted, crushed, grinded, or refined, converting the minerals into finished products for distribution.

Surface Mining Methods

Surface mining is a mining method used to extract minerals that are close to the earth’s surface.

Mining methods for surface mining include:

  • Strip mining. Strip mining removes thin layers of surface material in order to reach the mineral. The layer above the mineral is called overburden, and it typically consists of soil and rocks. This surface mining technique is commonly used to extract coal that is laying near the surface, and it is a method that is used to prepare the area for open-pit mining.
  • Open pit mining. Open-pit mining is a technique that involves drilling into the earth’s surface to set explosives. These explosions create a large pit for miners to access underlying rocks. This surface mining technique can be used to extract silver.
  • Quarrying. Quarrying is a process in which miners cut blocks of hard stone. Miners will also extract by-products of these hard stones, like sand, gravel, or small stones. Quarrying is made accessible by open-pit mining. This surface mining technique is typically used to extract granite, marble, and other hard stones.
  • In-situ leach (ISL) mining. In-situ mining is primarily used for extracting uranium, which is used for nuclear power. This surface mining technique consists of dissolving the mineral in place without moving rock from the surface layers.
  • Placer mining. Placer mining is used to extract gold from sand or gravel by using pans and water. Gold, which has a higher density than sand and gravel, will sink faster, making it easier to collect.

Underground Mining Methods

There are several minerals that cannot be extracted by surface mining techniques.

In this case, underground mining will be used. Because of the confined nature of underground mining, the extraction process is different.

Mining methods for underground mining include:

  • Blast mining. Blast mining, just as it sounds, utilizes explosives to remove hard rock layers, loosen rocks, and open up underground mining areas.
  • Room and pillar mining. Room and pillar mining consists of the construction of rectangular pillars to support the weight of the ceiling while miners clear out the minerals from around the pillars. This technique can be done by specialized underground mining equipment.
  • Retreat mining. Retreat mining is the process of removing the pillars from room and pillar mining. This underground mining technique strategically removes the pillars, extracting the remaining mineral from the mine. As the pillars are removed, the mine collapses onto itself. This is an incredibly dangerous underground mining technique. A lot of careful planning goes into the pillar removal process to prevent injury and death.
  • Block caving. Block caving is a large-scale mining method that requires a longer development stage than any other underground mining method. This method blasts a gap at the bottom of the rock mass which causes the rock above to break up and collapse to fill the void while the surface of the mie caves inwards.
  • Cut and fill mining. ​​Is a small-scale mining method that involves cutting horizontal slices in the orebody. Once the level is excavated, the level is backfilled and excavation moves up to the next level.
  • Drift and fill mining. Drift and fill mining is used when an orebody is wider than the drift itself. Drifts will be mined adjacent to one another, backfilling one before excavating another drift.
  • Longwall mining. Longwall mining is commonly used in coal mines and involves the use of a shearer set on a kilometer long track to grind coal from the mine face.
  • Shrinkage stope mining. Shrinkage stope mining is a highly productive mining method that is used to mine steep, uniform orebodies. Primary and secondary stopes are blasted throughout the orebody, with the primary stope being excavated and backfilled before extracting ore from the secondary stope.
  • Sublevel caving. Sublevel caving is used on orebodies with a steep dip. Ore is extracted from the footwall side to prevent fracturing. The orebody is blasted from the top down while the host rock on the hanging wall caves.

Mining Equipment for Soft Rock Mines Vs. Hard Rock Mines

Different mining tools are used for different types of minerals and mining techniques.

There are specific mining tools for soft rocks and specific tools for hard rocks, just as there are specific mining machines for surface mining techniques and specific tools for underground mining techniques.

The basic difference between soft rock mining and hard rock mining is that hard rock mining requires the use of explosive, and soft rock mining does not.

Soft Rock Mines

  • Do not require explosives for extraction.
  • Examples of soft rock minerals include salt, coal, bauxite, and potash.
  • All of these minerals can be mined using only specialized mining machinery.

Hard Rock Mines

  • Require explosives for extraction.
  • Examples of hard rock minerals include copper, gold, iron, lead, platinum, silver, uranium, and zinc.
  • In hard rock mines, hydraulic drills are used to drill holes where explosives can be inserted and then blasted.

Mining Tools and Equipment

There are a lot of different types of tools used in mining.

Instead of naming all these tools in one giant list, we've organized this guide into the different types of mining methods and the tools used for each one.

But before we dive into those specific categories, we wanted to share a list of mining tools and equipment by category so you can have a general understanding of what each category contains.

Here's a general list of mining tools and equipment:

  • Miner tools—tools that miners carry on them, like pickaxe and chisels.
  • Mining PPE—equipment that miners use to stay safe while working.
  • Surface mining equipment—all the tools and mining machines used for surface mining.
  • Underground mining equipment—all the tools and mining machines used for underground mining.

Now that we've covered things at a high level, let's dive into each specific category.
