underground mining rock bolting
Making Underground Mining Safer
Efficient and safe work practices are vital in any mining operation. In underground mine development and civil tunnelling, “ground support” is critical due to the high risk of rock falls and roof collapses in potentially hazardous environments.
Wilco Technologies specialises in ground support, particularly in resin set bolting. This process involves installing two-pack synthetic resin capsules into a pre-drilled bolt hole, where a steel bolt is inserted and spun to mix the resin adhesive.
Resin bolts have become very popular in many mines because of their increased lifespan, high loading capacity and reduced installation and mine rehabilitation costs. Wilco Technologies is at the forefront of this innovation with the ‘Trajectaflex’ Resin Firing System, a state-of-the-art solution for installing resin capsules in resin bolting.

Underground rock bolting with a Jumbo drill
Wilco Technologies ‘Trajectaflex’ resin firing system in operation. A Jumbo drills the bolt hole using the Trajectaflex system installing resin capsules and inserting the resin bolt. The rock bolt is pushed and spun to the back of the bolt hole mixing and bonding with the resin glue. Keeping the drill operator on the work platform for longer periods of time, the Trajectaflex resin firing system offers reduced bolting cycle times and significant increases in productivity and safety.
Drilling holes, filling with resin and loading bolts
Single Jumbo operator drilling holes, filling with resin and loading bolts. Wilco Technologies are specialists in Resin Firing System for underground mining, rock bolting using a jumbo drill. Since 2005, Wilco Technologies have manufactured and supported the Trajectaflex Resin Firing System for underground mining. Installed onto any Jumbo drill it provides significant increases in productivity and safety and reduces resin set bolting cycle times.
Revolutionary spring design
With the nozzle tip engaged at the collar of the bolt hole the operator can slew or dump the feed rail left, right or back and forward. With one of these movements the tip will align with the hole through the flex of the spring.
➊ Full extension nozzle located collar of hole
➋ Part flex in spring as boom or rail is moved
➌ Increased flex as nozzle tip enters hole
➍ Perfect nozzle location. Tip fully inserted into hole, back pressure slots are clear. Slight gap between nozzle tip taper and collar of hole
