Access-Excavation-Cross-St-Case-Study-Jul_Aug2023

PROJECT : 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
