Improved drilling process quality and productivity
Up until 2019 the drilling process Quality Control (QC) required a high level of data processing and analysis therefore limiting the possibility of having timely information in order to make opportune decisions once deviations in the process execution were detected.
Online QC allows to control and minimize blastholes collar and length deviations, number of re-drillings, improve drill speed, control operational parameters (RPM, torque, Pulldown, air pressure) relating actual performances with rock types, and monitor effective time and equipment utilization.
In 2019 the Drilling and Blasting Superintendence worked shoulder to shoulder with TIMining to develop a system that would automate and integrate online drilling process information, displaying the information in real time. Drillit software finally was implemented in July 2019 and Drilling and Blasting area supervisors were trained.
- Thanks to this collaborative work, today the following is possible:
- Monitor Drilling equipment status and position in real time.
- See drilling plan compliance in real time
- Immediately identify blasthole length and collar deviations
- Check for blasthole re-drilling
- Monitor process status and performance with mobile application anywhere in the mine
- Track drill rigs’ drilling path in order to optimize it
The benefits of implementing this automated process are to achieve the required granulometry, slope construction according to design, increase efficiency, safety and reduce the process’ costs. The detailed benefits are:
- Potential of 4.000 extra meters/month thanks to improved drilling path
- Real time detection of rock type anomalies using with drilling speed maps
- Reduction of blasthole length deviations
- Blasthole deviation reduction: Online identification of low blasthole density areas
- Real time control of operational parameter ranges of RPM, Pulldown, Torque and Air Pressure.
- Online fleet status: detailed maintenance and operational status.
