Continuous loading and the impact on your operation.
If you do what you always did, you will get what you always got.
Changing the current way of Drill & Blast decline or development operations towards continuous loading by using ITC loaders and Paus Dump Trucks will have sever impact on your KPI’s on Opex, ESG and QSHE.
- Increase of safety
- Energy savings
- Reduce carbon footprint
- Reduced operational cost
- Decrease of time to reach target
- Earlier ore excavation
| Benefit | Impact | Countability |
|---|---|---|
| Eliminate loading Bay Eliminate passing Bay Face work with electric drive |
LHD loading movement reduced to 0, Diesel consumption and Diesel particle reduced, LHD Maintenance reduced, Auxiliary bay blasting accounts up to 20% of your blast time, this can be reduced to 6-10% |
|
| Drill & Blast cycle reduction Muck loading, scaling, invert cleaning are 40% of a Drill and blast cycle |
Muck loading, scaling and invert cleaning with one machine, cleaning time reduction by 50% possible, lead to more blast per day |
|
| Possible to work on 30% decline | Will allow to change the slope from 9° decline to 13° decline |
Reduction of blasted road meters by 30%, time and cost saving |
| Optimize blast pattern to the best blast fragmentation to muck |
Increase the spacing to achieve bigger fragmentation, reduce drill holes |

Drill & Blast current systematic
Using LHD as mucking method has several disadvantages
- Need to blast a loading and turning bay for truck and LHD
- Common Truck dimension require passing bays for trucks
- Approx. 20% of blasting time is for auxiliary blasting
- LHD need to travel constantly from face to loading bay
- Diesel consumption for LHD to load muck and travel is high
- Diesel particles are influencing the environment
- Ventilation needs are very high for cooling and cleaning of air
- High risk of accidents due to high movement of LHD
- LHD maintenance cost are based on the travel distances
- Declines need to be designed to accommodate the LHD
- Common decline gradient with LHD/Truck combination is 9°
Focus on the mucking and scaling partvantages
40% of the complete Drill & Blast cycle time for:
- Collecting debris
- Muck loading with LHD
- Scaling with dedicated scaler
- Final cleaning of invert with LHD
Drill & Blast fast Decline & UG Development

Reference: Drill & Blast
- Project Grimsel Switzerland
- 34m2 cross section
- Pull length 3,6 meter
- 4 days each 5 blasts (3 blasts calculated)
- Support 1-2 bolts per meter
- Used wheel loader, 15% gradient
- After 6 month 2 month behind
- Finished tunnel 3 months ahead
- ITC turned the project around
Reference: Drill & Blast
ITC 312 Superloader loading in Breidal, Norway.
The geology in Norway is mainly composed of granite, making drill and blast the most used choice throughout the country.
We currently have 6 machines working there. Most tunnels are between 16m2 to 30m2.
Reference: LHD vs ITC Superloader
Weekly advancement in a jobsite in Norway, 2018-2019
Explanation
- Blue : planned heading, orange : LHD loading, green : ITC Superloader
- After only 5 weeks, they were already more than 1 week late with the LHD
- Once the ITC Superloader was there, it took 3 weeks to catch up the planned heading
- They were 2 weeks early on Christmas time
Reference: LHD vs ITC125
After only 80 meters
- In a 21m2 section, our ITC125 + 2 dumpers were faster than 2 LHD after only 80m
- They thought it would be faster after at least 200m
Reference: Case study (Kjøsnesfjorden)
One ITC loader (312N with loading boom H3) + 3x Paus ITC dumpers
Mucking time for 120-130m3 was 60-90 minutes (including scaling and cleaning of the invert)
Expected advancement : around 80m / week
Achieved advancement: 104m / week
Break the Norwegian record for drill and blast advancement with 175.8m in a single week !
«We are very please with the Paus units […] and the ITC loader, they are provinding very close to 100% availability, which is a must of sustaining good production.»
«In the equipment combination, the ITC loader and the PAUS units have proven especially effective.»
