As you can imagine that tires for mining and tunneling work in harsh conditions, it doesn’t get much tougher than this. Sharp rocks that constantly cut and bruise your mining tires, as you have to work with extreme loads, provide these harsh conditions. The only benefit might be that working underground you have less of a weather impact. However being underground then means that you have limited amount of space, so you want to avoid any type of unforeseen problems with your equipment or your tires, as this can cause a lot of problems and costs. A tire failure can cause both delays and costs to a project in addition that it might be a hazard, as these tires work under very high pressures and they do carry very heavy loads.
The tires will thus have to be extremely durable and have a
cut and crack resistant tread compound that will provide you with long service
life with limited unscheduled maintenance downtime, so that you can maximize
productivity. With the limited room to maneuver in the tunnels you will need to
have very steady and precise handling. The main vehicles used that you will
need tires for are your drill rigs that will drill into the hard rocks. Then
you have your underground excavator that can continue digging. They are then
paired with a special low height underground mine loader, that can lift very
heavy loads and then dump it into a dump truck which tend to be articulated for
better movability and load bearing properties. The dump truck can then
transport the rock and debris from the underground via the access roads.
The different equipment will have different tires that all
will have slightly different properties in addition to being able to withstand
the tough conditions that prevail underground and the heavy loads. The loader tires have to have excellent grip so that it can easily
fill the bucket without tire slippage. Your excavator tires will need to be
very stable so that it can dig up rocks without the excavator rocking back and
forth. The dump truck tires will need to have good driving properties as it
will leave the mine or tunnel through the access roads at higher speeds, so it
needs to have both good on and off road properties. For

Regardless if you work with tunneling or underground mines, the equipment used are similar and the work conditions will be almost the same. The good thing is that you can avoid bad weather while working underground, but the working conditions are still almost as tough as it gets. The combination of heavy loads and sharp rocks will need some very durable tires to ensure that you can minimize any unscheduled downtime. Underground is not the place where you want to experience a lot of problems, as you have limited space both to maneuver and where to repair failing equipment.
The main equipment used in mines and for tunneling are
similar to other major construction, so you will have excavators, loaders and
dump trucks and some other special equipment such as drill rigs. For underground applications the equipment
tend to be very compact to reduce the height impact in the tunnels. The loaders
will special type of underground mine loader and will require special mine loader tires. The Nokian Mine King L-5S is a slick
tire, which give you steady and reliable handling, so you easily can maneuver
in the narrow spaces. These tires can handle some of the heaviest loads and can
be used on some of the heaviest machines available. They have a very cut and
crack resistant tread compound that will give you extra long service life.
Good qualitymining tires will help you improve
productivity with the minimum downtime, but it requires that you also maintain
the tires properly. Proper cleaning of the tires at the end of the shift and
checking the tires for cuts, cracks and bruises. If you detect any problems a
tire specialist should further check them so that you can take any precautions
in terms of changing tires before you have a possible failure. Checking
remaining tread depth is also very important to keep track of when to change
the tires. The Nokian Mine King L-5S has tread depth indicator visible from the
side of the tire, which makes it easy to read the tread depth on a daily basis
without having to measure the depth.
Even though some of the equipment is the same as for other
construction applications, you will still need to make sure that they are
mining tires so that they can handle the conditions that are present there.
Regardless if you are focusing on earthmoving or forestry, adding high quality tires to your operations, will enhance your business performance. It is not only about adding value by being more productive, the overall cost needs to be factored in as well as the safety performance. Your number one aim should always be to avoid any personnel injuries, even how minor they might be. Accidents caused by negligence, equipment breakdown or tire failure, can often be limited by proper procedures in place. Aim to minimize any downtime, but being able to maintain the equipment through regular service, where the focus is on replacing any parts that is likely to fail before the next scheduled service. If you have too many breakdowns between your scheduled service times, then you need to increase the frequency.
equipment might need less frequent service, where only some regular visual
inspection of the equipment and the agriculture
needed versus mining equipment, where both the machine and the mining tires will take a harder beating. Both
will be durable, but mining tires operate in some of the harshest circumstance
and will need more frequent service, but also the regular visual inspection.
Daily cleaning and inspection of both the tires and the equipment is always
advisable to ensure that you can continue the next shift with less risk of any
problems. If there is some problems identified it can be worked on between the
shift and not disrupt the work intended to be done during the shift. Tread wear
should always be checked so that if the tires needs to be replaced, they can be
replaced before the start of the next shift.
Utilize the technical
tire manual to
ensure that you have the correct tires and dimension and you are using the correct
tire pressure. The manual covers the full range of tires and if there are
frequent tire related problems it might be that there is another model better
suited for the conditions that are present in your work situation. These tires
should be extremely durable and should have long service life even in the
toughest conditions, so if there are tire related problems it should be
something out of the ordinary or then your tire selection is not optimal and a
more thorough selection should be done.
When working down in the harsh conditions of a mine, you will both need to rely on your workers performing and that your equipment continue to operate with minimum downtime. Mines tend to be dark and dusty and working with heavy loads within confined spaces, where you need good maneuverability in small areas, while working side by side with other equipment.
With the plentitude of sharp rocks, the tires will
need to be very durable and puncture resistance, often achieved through some
form of reinforcement. Cut and crack resistance rubber compound is essential,
as you work in circumstances where any downtime can be very expensive and can
cause big delays, while the equipment is being repaired. These are not cheap
equipment and the tires are also not cheap tires, so ensuring that they last
and do not break down will make the operations more profitable.
Tire maintenance is key to ensure that the tires
are kept in good condition and that they are not damaged during the shift. A
visual inspection should be done daily at the end of the shift, to ensure that
you start the next day with good tires and good working conditions. Anything
that happens down in the mines will be more severe and costly than happening up
at ground level.
tires are built to handle the conditions that you
experience within the mines; this doesn’t mean that all tires are the same.
Some will have better properties for certain conditions, while other tires for
other conditions. Trying to save money on tires is often a very expensive mistake.
You basically need the tyre that fits for the conditions and environment that
you will be working within. Durability and the crack and cut resistance is key
to ensure low down time. The mine loader tires
and the articulated
dump truck tires need to be of the highest quality, with the
best properties for working in mines and the conditions associated with that.
Low rolling resistance of tire will still impact the fuel consumption down in
the mines and should be take into consideration when choosing tires.
When you deal with underground mines, you have by default tricky working conditions. Underground hard rock mining are created are created by digging holes and excavating to find minerals or metals. In practice it is very similar to building tunnels in part similar equipment is used. It is all about breaking ground and removing it, so you excavate and dump it in a dump truck for removal. For tunneling the aim is just the hole from one side to another, while the mines you just want to rich mineral rich compounds.
The working conditions tend to be similar between
tunneling and mining, as you have confined spaces; you carry heavy loads while
excavating and getting rid of broken rocks via dump trucks. The conditions for
the equipment is harsh, with very sharp rocks, so the tires will sustain
constant abuse while working. So from a
durability point of view, you will need the best possible tires. Maneuverability,
so that you can move in tight spaces becomes critical, good grip and then to
ensure that you have a good cut and crack resistant rubber compound.
When it comes to mining
tires, you can always create good puncture resistance
through using chains or deep groves. Groove indicators make it easy to read how
much depth remains. Avoiding unscheduled downtime due to tire failures or
equipment problems is something that you really want to avoid working below
ground. The limited space and the dependency of other vehicles make these
breakdowns expensive and often time consuming. You want trouble free service life from your
tires, to ensure a smooth operation. Good grip will ensure that you can work
safer and that work conditions will not slow you down. You also need to be able to maneuver with
good precision within the limited space and have good stability while you work.
tires and the mine loader tires
should be checked at the end of each day. The best is to wash them and see if
there are any visual damages. It is always easier to do a scheduled maintenance
that to do an unscheduled repair. Proper tyres will have low wear and low
rolling resistance, so that your fuel consumption will be low while working. Check
that you are operating with the correct tire pressure based on your load for
For underground mining it is important to have state of the art equipment and match those with the best in class tires for each of the different equipment. The basic workhorse equipment that basically any mining operation will have is the articulated dump truck for easy maneuverability and an underground loader. The underground loader is of load-haul-dump type often with a low profile to fit even in small spaces in the mine. The equipment is very durable and rugged and built to last. Good maneuverability is key for the equipment in the small tunnels in the mines.
machines need to be equipped with good mining tires, you need articulated dump truck
tires and you need tires for the underground loader. You then will need some
drilling and excavating equipment. Excavator and some drill rig or other type
of equipment to mine with is then the most used equipment down in the mine.
With these machines you get pretty far. All the equipment is very expensive, so
utilization is important to provide efficient mining.
tires you need tires that have very high cut and crack resistant rubber.
Driving precision and stability is key when you drive the special equipment
that is built to have high maneuverability in the narrow spaces. Load capacity
to keep up with the heaviest machines in the market is also essential. Consult
the tires technical manual to make sure that you select the
correct tire with the right load capacity for each machine, also make sure that
you have the correct tire pressure for the specific tire.
be very costly as the utilization rate diminishes, so it is important to keep
maintenance at the highest level. Wash off the tires at the end of each shift
and check the tires for any cuts or cracks. Tread depth and tire pressure should also
be checked on a regular basis to ensure that the tires are operating under proper
conditions. Repairing tires down in the mine is not the most convenient place
and it will disturb the working pattern and cause downtime that can affect also
the other equipment that are working down in the mine. Hopefully the regular
maintenance and the continuous checks will reduce any unforeseen downtime so
that operations can continue smoothly and at least the downtime due to tires can
