Working in the mining industry can be a dangerous place if you dont know what youre doing. Regular training is essential and understanding the machines youre 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? Heres a few of the industrys most common types of equipment and why theyre important for the job.
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 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.
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.
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.
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.

You make a great point about how drills are a very common piece of mining equipment. Choosing the right kind of drill tip can make a big difference in efficiency. Many drill bits will be tipped with synthetic diamonds to ensure that they are as durable as possible regardless of the rock and substrate involved. Thanks for your post.
It is true that working in the mining industry can be a dangerous place if we dont know about the machinery that are useful in mining industry. I hope your post will help people to know about the most common types of mining equipment and how to use them properly. Thanks
Thanks for the information. This really help to understand the different types of equipment you can expect to see in a mine. Drilling is such an important part to the mining process. Drilling and blasting go hand in hand to help break up the hard ground. After all you can gather the material your mining if you cant get to it.
Understating what type of mining equipment like core boxes, seems like a good place to start for beginners. Theres really now way to do a job properly unless youre familiar with the tools and equipment youll be using. It might also help with improving safety.

I like how you mentioned that drills are needed in the mining industry because these are going to be used in creating holes descending underground. Its also intriguing to learn that the blasting tools are mainly used to break down and fracture the materials. Well, if I had a mining company, I would make sure to place industrial fans in there because these will provide air stream.

Iliana got sick last Monday, and now Gabby and Mommy are sick. I've been wearing a mask at home hoping I'll be healthy for the Secular Summer Retreat this weekend, but I feel like I'm fighting a losing battle.
Native people in Canada are trying hard to return to their names before murderous Catholics forced them to adopt white names, but the Canadian government hasn't exactly been making this easy for them.
You've probably heard that your body raises its temperature in response to a disease (what is called a fever) to help kill off the disease. But, the temperature usually only gets into the low 100s, which isn't enough to kill pretty much anything. So then, how does the fever actually help?
Had a great vacation with my wife and kids. We went to Sleeping Bear Dunes and stayed at The Homestead. However, neither my girls nor Lucy appreciated the fireworks last night. The girls cried from the noise and had to sleep in the basement, and Lucy pooped and peed on the carpet.
A third mass-children-grave has been discovered on the land of a Catholic school in Canada and another 182 child remains were discovered, bringing the total to well-over 1,000, and growing. One arch-bishop in Canada is really upset, not because of all the children his religion murdered, but because people are blaming the Catholic church for murdering all these children. Over in Europe, 10 more of their clergy, including a cardinal, have been indicted in an embezzlement case of $415,000,000. Meanwhile, Catholics are still trying to refuse communion to Joe Biden for not being moral enough to be a Catholic.

When the hammer crusher is working, the motor drives the rotor to rotate at high speed, and the material enters the crusher cavity evenly. The high-speed rotating hammer head impacts, shears and tears the material, causing the material to be broken. At the same time, the gravity of the material makes the material from The high-speed rotating hammer head rushes towards the baffle and sieve strip in the frame body. The material larger than the size of the sieve hole is retained on the sieve plate and continues to be hit and grinded by the hammer until it is crushed to the required output particle size and finally discharged out of the machine through the sieve plate . Main Advantages 1. The working hammer head is cast with a new process, which is wear-resistant and impact-resistant. 2. The crushing ratio is large (generally 10-25, the highest is up to 50). 3. Hammer breaks the structure seal of the machine body, which solves the problems of dust pollution and ash leakage in the crushing workshop. 4. The overall design is beautiful in appearance, compact in structure, few wearing parts, easy to maintain, etc. It is an upgraded product. 5. Compact structure, good wear resistance and easy maintenance. Details Show FieldUsage
