Mining and tunneling tires made for the harshest conditions

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.
