Most Common Types of Mining Equipment in Use in 2023

Underground mining is the part of the mining industry outsiders first think of, despite being less common than mining for surface material.

Unlike surface mines, which benefit from open areas, fresh air, and a soft digging surface, underground mines are confined spaces surrounded by hard stone requiring unique tools to conquer.

For example, while surface miners have to cut through thin layers of soil for a portion of their work, underground miners have to saw through a much more rigid material.

As a result, underground miners need equipment that can cut through hard rock and heavy-duty mining equipment that can fit into tight quarters.

Additionally, underground mining requires mining machines that don't emit hazardous fumes.

Because of the cramped space and lack of fresh air in underground mines, those emissions will create health hazards that don't exist in surface mines.

In other words, you will need strong equipment that can drill through hard rock but is safe for your underground mining site.

Meanwhile, you won't have to limit your tools as much for surface mining, and you'll likely need more mining machines than you would underground for the various mining methods you can employ above ground.

Working in the mining industry can be a dangerous place if you don&#;t know what you&#;re doing. Regular training is essential and understanding the machines you&#;re working near or operating plays an important role in all aspects of the industry.

Each type of mining equipment comes with its own set of mining activities. The most common types of mining equipment vary depending whether the work is being carried out above or below ground or mining for gold, metals, coal or crude oil. From drilling machines to excavators, crushing and grinding equipment &#; the mining industry comes complete with all the right tools. New to the job and want to find out what it all means? Here&#;s a few of the industry&#;s most common types of equipment and why they&#;re important for the job.

Mining Drills

Probably one of the most common pieces of mining equipment, drills are an important part of the underground mining operation. Underground mining is carried out when rocks or minerals are located at a fair distance beneath the ground. But then they need to be brought to the surface. Underground specialized mining equipment such as trucks, loaders, diggers etc. are used to excavate the material and are normally hauled to the surface with skips or lifts for further processing. Drilling is normally required to place explosive charges to liberate the minerals from the overburden material. Underground mining techniques have progressed significantly over the past years, including using remote controlled machinery.

Drills assist in creating holes descending underground. If miners are required to work underground, drills can also be used in ensuring the holes are large enough to serve as a portal for miners to enter. Directional drilling is also a type of mining technology where miners will use the tools and certain methods to drill wells.

Blasting Tools 

Blasting tools are an essential part of the mining industry and are used to break down and fracture materials (usually rocks) by use of a calculated amount of explosive to liberate the sought-after product from the waste material. Blasting is also used to remove pockets of unwanted material that are preventing mining machines and personnel to get to the seam containing the materials of interest. Unmanned drill rigs will drill holes at pre-determined depths and positions on a blast face to ensure that a particular size fraction is achieved and that little of the overburden is liberated with the blasting to reduce material handling costs.  Once this process has been completed, an excavator is used to recover the blasted rocks and other debris that has been dislodged during the blasting.  The material is then conveyed to a central conveying system which will take it directly to the surface or via a skip and hoist system.

Blasting equipment is used for both underground and open pit mining operations and is known to be one of the most hazardous aspects of the job.

For mining operations to be successful good blast designs are absolutely vital as poor practices and excessive explosives can result in damage to rock structures causing unwanted caving.

Earth Movers

For above ground mining, earth movers are utilised regularly to carry loose soil and earth from one location to another. Earth movers play an important role in the mining industry because the equipment is specifically designed to work on large earth-moving and mining projects for a faster and more practical process. Used for digging, pushing and transporting the earth, they require the specialised skills of an operator.

Earth movers are heavy mining equipment that the industry would struggle to survive without and work hand in hand with bulldozers. Earth movers are normally used for removing overburden or waste material, which enables the excavators to remove the material or mineral of interest. Bulldozers are used to move this overburden material around to create a working surface for other equipment such as haul trucks and excavators.

Crushing Equipment

As its name suggests, crushing equipment is used to crush rock and stone. Designed to achieve maximum productivity and high reduction rate, mining crushing equipment can come in a variety of different types for a range of jobs.

Crushing equipment is specially configured to break down the hard rock matter or gravel to a manageable size for transportation or conveying. They are valuable pieces of equipment in the industry because they reduce the costs associated with handling of larger sized material and also ensure efficient liberation of elements of interest in downstream processing of the material. In an opencast or strip mining operation, the run of mine (ROM) material is normally transported to the primary crusher by haul trucks, and in underground mining operations it is conveyed to the primary crusher. Crushing equipment is important to the mining process because it reduces the use of precious excavated resources and eliminates the amount of material on site.

Feeding, Conveying, and On-line Elemental Analysis Equipment

Once the excavator transporter brings the raw material to the crusher for processing, the feeding device feeds the material into the crusher and in return the material is screened and all oversized material is recirculated back to the crusher to ensure correct size fraction is obtained. This weighbelt &#;feeding&#; equipment, usually referred to as &#;Weighfeeders,&#; conveys and controls the feedrate into the crusher to improve crusher efficiency.

Feeding and conveying equipment are necessary to the mining industry to move and control material flow within a mining and processing operation to facilitate efficient operation of equipment and determine operating rates and yields. In some instances secondary crushing is required prior to processing of the material. Once the material is at the correct size, fraction processing can occur which could include, milling, flotation, leaching etc.

Belt scale systems let you monitor production output and inventory, or regulate product loadout, while providing vital information for the effective management and efficient operation of your business.  There are elemental crossbelt analyzers that provide real-time quality analysis of critical process streams to facilitate sorting, blending and out-of-seam dilution control. While materials are on the troughed belt conveyor, an automatic sampling system (which could be single or multi-stage) can take a representative sample directly from the moving material stream.  (Take a look at this video to see how a sampling system works.)  Weighbelt Feeders that convey and control feedrate accurately and reliably can reduce material consumption, help maintain blend consistency, and increase profits.

Flow measurement systems provide continuous, real-time flow measurement of free-falling materials or dense phase, pneumatically conveyed bulk solids, which is important to ensure and maintain product quality and process efficiency.

All these common mining tools are crucial to the industry and assist in getting the job done efficiently and cost effectively.
