Common Mechanical Repairs Performed on Mining Equipment and How to Avoid Them 

Mining equipment is an essential component of any successful mining operation. These machines are subjected to heavy use and abuse, so it’s no surprise that they require repairs from time to time. In this blog post, we’ll look at some of the most common mechanical repairs on mining equipment and how to avoid them.

Hydraulic equipment

Hydraulic machinery, such as hydraulic shovels used for digging, extracting and moving earth or mined materials, is one of the most common mining machines on-site. Since these machines are used so frequently, they are vulnerable to a variety of common faults and repairs. One example is hydraulic fluid leakage from hoses, valves or seals. This can reduce efficiency because the machinery has to work harder to achieve the same result and it can also lead to overheating if not addressed.

Cavitation is another problem that can occur with hydraulic equipment. Cavitation occurs when tiny bubbles form in a liquid as a result of a pressure drop, and these bubbles then collapse violently. This process generates heat and noise, as well as damages metal surfaces, causing them to wear down faster. To avoid cavitation, ensure that your hydraulic equipment is properly maintained, including checking fluid levels regularly and keeping all filters clean.

Mining drills

Mining drills are a necessary tool in any mining operation and as such should be in good working order at all times. If a mining drill is not properly maintained, it can lead to more frequent breakdowns and higher replacement part costs, resulting in lower productivity and increased operating costs. Regular maintenance also reduces the risk of accidents occurring while underground machinery is being used, as well as extending the life of the equipment.

Leaks, faulty valves, broken hoses and cracked or worn seals are all common problems with mining drill machinery. Regular mechanical servicing is required to help prevent these types of problems from occurring.

Conveyor belts

A conveyor belt is an essential piece of machinery that must always be in good working order when transporting materials from one location to another. Several common problems can affect your conveyor belt system if it is not serviced and maintained regularly, including damage to the rotary valve (chute). This problem occurs when material accumulates against the chute overtime, causing excessive wear on the seal and small amounts of leakage into bearing housings, resulting in premature bearing failure.

To avoid this problem, a conveyor belt system should be lubricated and cleaned regularly. Depending on the severity of the damage, it may also necessitate the replacement of bearings or an entire housing unit.


Earthmovers play an important role in the mining industry, as they are frequently required to move large amounts of earth. While they are designed to withstand some wear and tear, regular maintenance is still required to ensure peak performance. Problems with the hydraulic system are a common occurrence with earthmovers. This can be due to several factors, including dirt and debris getting into the hoses or filters, low oil levels or simply old age.

If you notice any problems with your earthmover’s hydraulics, it is best to have it serviced as soon as possible to avoid more serious damage. Other common earthmover repairs include replacing worn out parts such as tracks, teeth or buckets.
