Abstract
“Holing has been a problem in uunderground deep level gold mines because of the
inaccuracy of tape measurements, especially a false holing between the current
workplaces, the mined-out areas and the workplaces that are advancing towards one
another in mines.” This research investigates the comparative accuracy of mine
surveying methods in determining breakthrough (or “holing”) positions in deep-level
mining environments. Accurate breakthrough positioning is critical for ensuring mine
safety, optimizing excavation processes, and adhering to statutory requirements.
Using a quantitative research methodology, the research assesses the precision of
traditional tape measurements versus Total Station measurements. Data was collected
and analyzed using statistical analysis to evaluate the margin of error associated with
each method.
The findings reveal that Total Station measurements offer superior accuracy and
reliability, with error margins falling within the permissible limits outlined by the Mine
Health and Safety Act 1996 (Act No. 29 of 1996) and the Standards of Accuracy for
Surface and Underground Mining. In contrast, tape measurements exhibited a higher
susceptibility to cumulative errors, particularly over long distances and under deep-level
conditions.
The study recommends the use of Total Station technology for breakthrough
determination in modern mining operations. These results align with previous research
by Amezene Reda and Bedada (2012), who also demonstrated the higher accuracy of
Total Station measurements in similar comparative studies.
