When working in underground mines and doing tunneling work, you will face really harsh conditions and your tires will be heavily abused by the surroundings. This of course calls for some of the most durable mining tires that can be produced. Being deep in the mines is not a place where you want to have tire failures that is why it is so important to select good quality mining tires that can handle the conditions with long trouble free service life.
The Nokian Armor Gard MINE are specially designed mining tires for performing in the conditions that are present in the mines. These tires are stable commercial tires for mining machines; predominantly drill rigs and other mining machines. The compound used is cut and crack resistant, to ensure that the sharp rocks don’t cut and damage the tires. Deep in the mines is not a place where you want to have tire problems.
In the mines due to its limited space to maneuver, you want to make sure that your tires have precise handling so that you can maneuver with precise steering and stability. Without precise steering in narrow tunnels, the machines will have problems and will not be able to maneuver with the same speed and efficiency. The cut and crack resistant compound ensure that despite the sharp rocks and the constant bruising of the tires will not damage them nor will they crack under the heavy loads that are put on them. Proper tire selection will ensure that you limit or eliminate any problems related to the tires.
The Nokian Armor Gard MINE will give you the steering precision and stability that you want from a tire combined with the durability so that you have a long and trouble free service life, with low fuel consumption. You should check the technical tire manual to ensure that you have the right dimensions for your machines and that you the tires can handle the loads that you are working with. Check also for the tire pressure. In addition to ensuring that you have the correct tire inflation pressure and that you check the pressure on a regular basis, you also need to check the tread wear, so that you know when you need to change the tires as the tread has worn out.
The main objective of tire maintenance is to avoid letting small tire related problems to cause bigger problems, accidents, damages or injuries. When it comes to the tires for heavy equipment, the tires are very big, the tire pressure is very high and the loads that are being carried are very heavy. In addition when problems happen they are not necessarily easy to fix or attend to. The problems can occur deep in the forest or deep down in a mine. These places can be hard to reach, costly to repair and the downtime can be long, resulting in delays and costly repairs.
These facts puts more pressure on having an effective proactive tire maintenance program in place to strive towards reducing any unscheduled downtime and avoiding serious problems such as personnel injuries and costly accidents. The frequency of the preventive maintenance should be assessed based on historical data taking into account the equipment used, the specific tires used and any irregularities. For mining tires working deep down in a mine, working in extremely rough conditions, the maintenance will of course differ than for backhoe tires doing road maintenance and the cost implications might differ. The same goes for forestry tires, where getting stuck deep in the forest will have some potentially significant cost impacts.
Not only the frequency and the quality of the maintenance is
of important, the quality of the tires and that the tire selection process is
done correctly becomes almost as important if not even more important. The
procurement department has to work share the information to ensure that they
both work together at achieving the best overall cost effective solution that
increases productivity and reduces all related costs including both the
scheduled and unscheduled maintenance costs.
Hopefully by procuring the right tire, that are optimized
for the work that is being performed and are made for the loads and conditions,
then you will have less maintenance and fewer problems, resulting in better
work morale combined with fewer personnel injuries. Delays and waiting around
for things to get fixed is never good for the workers and it is costly and
often causes delays to the overall project. So if you notice too many
unscheduled downtime, then check both your tire selection and your maintenance
Depending on where you aim to work, will determine what type of tires that you will need. There are different tires for different work verticals, you will have your earthmoving tires, that will differ from your agricultural tires that will be very different from mining tires. Some will require a much more cut and crack resistant compound and often they will need to be steel fortified as well.
Mines represent some really harsh work environments. Being in underground mines, means no sunlight, limited space and being surrounded by sharp rocks. This is not the ideal environment neither for equipment nor tires. If you are going to bring down equipment into mines, you want to make sure that you have the best possible equipment. You want to make sure that the equipment can handle the task at hand and that the tires will be up for the challenge. These tires have to be extremely durable.
There are a few key equipment used in mines and when making
tunnels, they have in common that they have to be able to work in narrow spaces
and need to have tires that are very precise when it comes to steering response
and ability to turn even at standstill. You will mainly have some form of drill
rig, an excavator, a loader and dump truck. A mine loader has a much lower height so that
it can operate in the tunnels. To match these, you will need to have wheeledloader tires, wheeledexcavator tires and tires for dump trucks and drill rigs. When
you have mining tires for these, you know
that they will be some of the most durable tires designed for long service
You will enjoy a long service lie if you ensure proper tire
maintenance. You will need to ensure that the tire pressure is as detailed in
the technical tire manual, that they tires are inspected for cuts, cracks and
other visible damages. A tire specialist should clear all visible defects
before work can continue and if the damage is deemed serious the tire should be
changed as soon as possible to avoid breakdown while in operation. It is
advisable to clean the tires daily after the shift and then do the visual
inspection. Check also the tread depth so you can keep track of when you will
need to change the tire as it has reached the end of its service life.
The better the quality, the longer the service life and
costly unscheduled downtime can be minimized and the safety improved. You will
also see positive effects on the productivity, as the tight space in the mines
is not a place where you want to have a lot of problems with faulty equipment.
Computers are getting more intelligent, and with artificial intelligence, the advantages are clear of using machines versus people as drivers. The key is just to make it safe and reliable enough. With self-driving vehicles you can basically operate around the clock, to better utilize your investments. You can’t of course cut out all the people from your operations, but machines don’t get tired, they don’t need breaks and they don’t make mistakes due to fatigue or lack of concentration.
Self-driving equipment has been tried in quarries, where they
see a big saving on not having to fly in personnel to remote areas, higher
utilization of the equipment and much lower labor costs. Instead of having 4.5
mean per vehicle around the clock with time restrictions, you can equip it with
self-driving technology. For long haul trucks this has also been tested along
with self-driving cars. The technology is not far from being launched at a
bigger scale. Then we will have a lot more trucks driving around the clock.
The technology will not be cheap initially, until demand
gets really high, but the savings can be big from the get-go. It does require
that you can make sure that the equipment will run without breakdowns and that
the tires will withstand the constant wear. For the truck
tires, you will need to be able to effectively monitor the tire
pressure in all the haul tires on the rig and have a
procedure for how the trucks can stop for fuel and for tire monitoring. With
low tire pressure you will have higher tire wear due to higher rolling
resistance. Also the fuel efficiency is negatively impacted. Most of the tire
blowouts are due to low tire pressure, so it is a real and quite big issue.
This is a reason why you now and then see tire residue on the highways. The
trucks don’t notice the tire failure and continue driving.
For big heavy equipment used in mining, you will have big mining tires with extreme
conditions and you can easily have tire failures if the tires don’t have
continuous maintenance and check for cuts and cracks. This will be one of the
challenges for the future, how to make sure that proper maintenance is done and
to avoid tire failures.
Trying to find tires for your mining equipment will not be that easy and since the consequences of selecting the wrong tires can become an expensive ordeal. Mining tires need to operate in some of the toughest conditions available to tires. Mining tireswill be daily exposed to conditions that would break most tires. Sharp rocks, heavy loads and the constant bruising and cuts of the tires that is not allowed to affect the tires that need to be able to continue working with minimum downtime.
You also have a narrow space to operate, so the tires need
to give you predictable steering and maneuverability, so you can imagine the
scenario of having the narrow tunnels filled with equipment that are having
problems. This scenario of course needs to be avoided. Any problems with the
equipment or the tires will cause problems and delays, which is why this puts a
lot of pressure on selecting tires that are durable enough to manage in these
Setting up sufficient scheduled maintenance process that
will catch minor problems before they cause major problems. Daily inspections
at the end of the shifts tend to be better than before the shifts as you have
time to fix the problems if they are identified at the end of the shift
Depending on the use of the tire, it will in most cases require a different
tire. An excavator tire will have a different tread pattern than a mine wheelloader tire, so it is important to use the technical tire
manual to ensure that each of your equipment gets the tires that are optimized
for the intended use.
This is why it is important to use the technical tire manual
to ensure that you select the correct mining tires for each piece of equipment
so that your excavators, loaders, drill rigs and dump trucks gets the correct
tires for its intended use. You will need to make sure that the ones that require
grip will have that and for the tires that will need better load bearing
properties will have that. The manual will also guide you in what tire pressure
the tires should have and what is the maximum load, so that you can avoid
having problems from using them or selecting the tires wrongly. With the
correct selection you will have tires that will work effortless with minimum
When you work underground you definitely have some of the toughest conditions for tires. With the constant heavy loads and sharp rocks, causing cuts and bruises to the tires day in and out, you need to make sure that you have some of the most durable tires available. Underground is not the best place to have tire related problems due to bad tires or bad tire maintenance. This is what makes the tire selection so important as you do not want unscheduled downtime and project delays that can be very costly.
will need mining tires that have all of these
properties, such as durability, good wear resistance, great grip, heavy load
bearing and self-cleaning tread. Tires for the drill rigs also need special
highly cut resistance carcass to protect from freshly blasted rock. Good
maneuverability is also very important as the space in tunnels and mines is
limited, so you will need to maneuver and turn precisely with good control.
is always advisable to consult the technical
tire manualso that you can check
regarding the load levels and the inflation pressure for the tires for each
machine. It will also guide you for the best replacement tires once your tires
are worn out. Since tire selection is so important to ensure the best productivity
and each machine will require special tires with specific tread design, you
will probably have numerous different tires for your different equipment used,
as you will have special mining condition loader tires and excavator tires,
that are often more durable than the tires for same equipment in other working
reliable tire that can give long trouble-free service life. It is recommended
to clean the tires and check them for any cuts or cracks, so that you know that
they are in good condition for the next shift. Tires tend to have good tread
level indicator that makes it easy to read how much tread you have left, so
that you can change in good time. With proper service routines and enough
scheduled maintenance so that you can limit or avoid any downtime. Proper tire
selection is of course an essential part in avoiding unscheduled downtime, if
you experience above industry average downtime, consider using different tires
or switch tire brand for a more durable mining tires
Heavy equipment will need special tires. There is different equipment for the various tasks that needs to be performed. If you e.g. need digging, or loading or transporting, you will need different tires as the requirements changes. Common for all these tires is that they need to be able to handle high loads, so just that makes them different than normal car tires. The size will also be considerable bigger and they will use a higher pressure. Mining tires, agriculture tires or forestry tires, they are all areas where you will need state of the art tires.
Durability is key as any downtime for these
vehicles translates to a high cost. Unscheduled downtime will cause delays,
might delay work for the other machines, this is where the biggest costs can
come from. The machines often work in pairs, where one does one task so that
the second machine can do the next task. For example, an excavator does the
digging and the loader then removes the material, if the excavator
tires cracks, then your loader will have to wait until
the tire is repaired or changed. From a safety perspective it is always better
to work with the tires in special designated areas, the tire pressure is so
high that you need to be cautious and inflating tyres should be done with a
Scheduled maintenance is where you should be able
to detect issues with the equipment or the tires. Fixing or replacing tires
during maintenance is a big cost saving versus any unscheduled downtime. Checking
the tires through visual inspection should be carried out after each work
shift. Good durable tires help to avoid downtime; tires that have special cut
and crack resistance rubber compound and reinforced sidewalls will help if the
equipment operates in harsh conditions. Stability
will be important for excavator to prevent the equipment to start rocking;
stabilizer legs should be used to add stability to it. Control to be able to
maneuver though difficult terrain.
Superior grip is important so that the equipment
can move freely without struggling or getting stuck. You want the equipment to
be able to move quickly freely not to slow down your operations. This is
regardless of what weather conditions you have or what surface you are
operating on, grip, stability and durability will be of utter importance.
