Technology News – Boxhole Borer Has Safety, Operational and Cost Advantages

A machine that improves safety during the cutting of boxholes (ore-passes) and travelways in underground mining operations has delivered impressive results in trials conducted at a South African platinum mine. The technology is a joint effort by Sandvik Mining and Construction and platinum mining company Lonmin. The ABH 1600 boxhole borer was built by Voest-Alpine Bergtechnik, Sandvik’s Austrian subsidiary. It was delivered to the Lonmin Eastern platinum mine in February 2005. There, it was deployed underground on the Number 8 Level (320 m or 1,050 ft below the surface) at the mine’s Newman incline shaft.
