KIRUNA. During September LKAB’s newest rig for drilling opening holes, Epiroc Easer L, will be tested at the SUM project’s Konsuln test mine.
“Easer L is already available on the market, but we will be the first customer in Europe to use it. The rig can drill opening holes up to a maximum of 60 metres. We will start by test drilling 40-50 metres and then evaluate the results,” says Carlos Quinteiro, a specialist with LKAB’s mining engineering department, and the project manager for SUM subproject 1, the mine’s layout and technology.
The drill rig will initially be used at level 436 in the Konsuln mine, which is the first level that has an increased sublevel height – of a total of 40 metres.“With an increased sublevel height, we have to be able to drill longer opening holes than our existing rigs can handle,” says Carlos Quinteiro.
A number of different tests will be carried out to check LKAB’s quality and productivity requirements. Only after an acceptance test has been performed will a decision be made on whether Easer L can be used in production at Konsuln.
