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%
  • Reduced carbon footprint
  • Diesel cost savings
  • Ventilation needs reduced
  • People safety increased
  • Operational cost savings
  • 10% more blast advance
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
  • reduces capex of separate scaler
  • 1 blast on a two blast cycle = 50%
  • More time for roof protection
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
  • Saving on drill time & cost
  • Saving on explosives up to 30%

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:

  1. Collecting debris
  2. Muck loading with LHD
  3. Scaling with dedicated scaler
  4. Final cleaning of invert with LHD

Drill & Blast fast Decline & UG Development

Continuous loading by ITC loader and Paus Dump Trucks

  • Implement ITC continuous loading in the D&B cycle
    • Eliminate seperate scaling machine
    • Increase heading speed
    • Increase safety
    • Increase block size blast fragmentition for optimized loading and drilling
  • Implement Paus Dump Trucks in logistic (Diesel or BEV)
    • Reduce or eliminate turning bay
    • Reduce or eliminate passing bay
  • Eliminate LHD loading of Trucks

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.»
Words from the site manager of Kjøsnesfjorden jobsite in Norway
