9 Percent Increase in Six Month Average Meters Drilled<\/strong>
Ever Increasing Safety and Productivity<\/em><\/p>\n

Owned and operated by BHP Billiton, Olympic Dam is Australia\u2019s largest underground mine site with more than 450 kilometers (279 miles) of underground development. The underground mine produces 10 million tons of ore per year using the sublevel open stope mining method.<\/p>\n<\/div><\/div><\/div><\/div>\n\t\t\n\t\t\n\t<\/section>

Boart Longyear has been working at Olympic Dam as part of a long term agreement with BHP Billiton. As the operation continues to grow, improved productivity and safety is demanded for exploitation of newly defined ore zones. Boart Longyear has answered this need by developing drilling technologies and methods for improved diamond core drilling.<\/p>\n

The past introduction of rod-handlers, by Boart Longyear, reduced drilling contractors\u2019 exposure to the manual handling of rods, leading to limited occurrences of hand injuries. Boart Longyear also participated in a study involving rig-moves which resulted in improved site move time by 11 percent. Now Boart Longyear has developed and implemented the Drill Control Interface (DCi)<\/a> to increase the efficiency, productivity and safety of the LM\u2122 series of underground diamond core drill rigs.<\/p>\n<\/div>

The Challenge<\/span><\/h2>
\n

Increase productivity of underground diamond core drilling<\/strong><\/p>\n

Boart Longyear provides diamond core drilling services at the Olympic Dam mine site. Diamond drilling is used to extract rock samples (core) for analysis of the Olympic Dam ore body geometry and to collect geochemical information which will be used to create block models for planning and extraction of future resources.<\/p>\n

Boart Longyear was able to introduce the DCi<\/a> to not only increase productivity, but to also enhance safety for the drilling contractors.<\/p>\n<\/div>

The Solution<\/span><\/h2>
\n

DCi increases meters drilled<\/strong><\/p>\n

Over a six month period (May \u2013 October 2013) Boart Longyear used an LM\u212275<\/a> drill rig with the DCi to drill a total of 5,726.3 meters using a BQTK size diamond core bit. This was an increase of 907.7 meters drilled over the previous six month average, which resulted in a unit cost improvement of $2.90 per meter average and monthly productivity increase of 13.5 percent.<\/p>\n<\/div><\/div>
