Mining Tools: A Complete Guide to Mining Industry Equipment

Mining tools are the equipment used in extracting a wide array of minerals from the earth.

Mined minerals are used in almost every consumer product—from cars, to electronics, to jewelry and more. And 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.

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

Here is a menu to help you navigate this guide:

Mining Industry Overview

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

The type of minerals and mining techniques that a mining operation is trying to extract will directly inform which tools miners use in their work.

However, there are three steps that are consistent for both surface and underground mining:

  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

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

Surface mining methods 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 

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.

Underground mining consists of:

  • 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.

Types Of Mining Tools

Different mining tools are used for different types of minerals and techniques. There are specific mining tools for soft rocks and specific tools for hard rocks, just as there are specific tools for surface mining techniques and specific tools for underground mining techniques.

Soft rock mines—like those made for the extraction of salt, coal, bauxite, and potash—do not require the use of explosives for extraction. These minerals can be mined using only specialized machinery.

Hard rock mines—like those made for the extraction of copper, gold, iron, lead, platinum, silver, uranium, and zinc—require explosives for extraction. In this case, hydraulic drills are used to drill holes where explosives can be inserted and then blasted.

What Types of Tools Do Miners Carry on Them?

To this day, miners still use traditional mining tools like pickaxes, hammers, chisels, and shovels for both surface and underground mining.

mining-tools-for-miners

In addition to those mining tools, miners have the following personal safety equipment on them at all times:

  • Air respirator systems. For breathing clean air.
  • Cap lights. Lights that are attached on top of protective headwear.
  • Detection solutions. For locating miners.
  • Fall protection. An array of safety tools to protect miners from falling. 
  • Hearing protection. For working in loud conditions.
  • Miner’s pouch. A miner’s belt that provides lumbar support and carries cap light battery packs, tools, and a self rescuer.
  • Protective communications. Wireless two way communications, plus a two way phone for emergency situations.
  • Protective eyewear. To protect the eyes. 
  • Protective headwear. To help protect the head from falling debris, etc.
  • Reflective clothing. A safety measure so miners can easily be seen.
  • Self-rescuers. A personal emergency respiratory protection device against carbon monoxide and other harmful noxious gases.

Dozers 

Dozers are earth-movers that drag dirt from one area to another.

Dragline excavators

Dragline excavators are used in strip mining to remove overburden. The massive bucket system is attached to large booms and dragged across the surface of the earth for excavation. This is one of the largest pieces of land equipment used in any industry.

Ventilation systems

Ventilations systems are crucial for workers to be present in the mines due to the noxious nature of coal and, specifically, coal dust. These systems are used to provide clean air for workers and regulate temperatures underground.

It’s important to note that underground mining tools that operate in an enclosed environment are no-emission machines. They are specially built to still have the power to move tons of rocks at a time in these harsh conditions.
