Melbourne, Australia – 9 July to 15 August 2023
Case Study Details
Access-Excavation-Cross-St-Case-Study-Jul_Aug2023PROJECT : 91 x 7-8 m deep 600mm Cores
SUBSTRATE : Up to 300MPa Basalt
PLACE : 6 Cross St Footscray, Melbourne, Australia
DATE : 9 July to 15 August 2023
COMPANY : Access Excavations
ENGINEERS : Joel & Kyle Dazenko
DRILL RIG : HPM 100J, IMT A140
DRILL BIT : 600mm Core Drill, Betek TCT Teeth
SUMMARY OF RESULTS IMT A140 drill rig using 0.8% Complex42™
79.6% Less Teeth consumed per hole
43.7% Less fuel consumed per hole
27.4% Faster drilling time
SUMMARY OF RESULTS HPM 100J drill rig using 0.8% Complex42™
69.8% Less Teeth consumed per hole
39.6% Less fuel consumed per hole
26.5% Faster drilling time
Key Findings:
1. Fuel and Operational Efficiency: Based on a diesel price of $2.09/Litre
Savings of approx. $95.05 and $110.07 per hole for IMT 140 and HPM 100J respectively when using Complex42™. Distributed across 91 holes, potential fuel cost savings amount to approx. $9,332.96.
2. Labour Saving: Based on a wage of $50 / hour
Saving of approx. 69minutes and 76minutes per hole for IMT 140 and HPM 100J respectively when using Complex42™. Distributed across 91 holes, potential labour cost savings amount to approx. of 6,597.5 minutes or 109.9 hours x $50 for a total saving of $5,497.90
3. Teeth savings: Based on $18.40/tooth
Saving 6.17 and 7.17 per hole for IMT 140 and HPM 100J respectively when using Complex42™. Distributed across 91 holes, potential tooling cost savings amount to approx. 607 teeth x $18.40 = $11,168.25.
4. Tool Wear Reduction:
Significant reduction in wear on drill barrels’ hard facing with Complex42™. Using traditional methods, hard facing would typically last 2-3 days in hard basalt. With Complex42™, the HPM 100J drilled up to 252.6 meters and the IMT 140 achieved a depth of 355.7 meters with only one changeover. The total cost for traditional methods would be: (8 + 11) barrels Å~ $250 = $4,750. Hard facing savings amounted to $4,500.
Total Savings: $30,499.11
