Interaction between shotcrete and rock: experimental and numerical study
At LKAB’s underground mines in Malmberget and Kiruna in northern Sweden shotcrete and rock bolts are the main rock support elements. A safe working environment for the miners and high accessibility to the mine are important issues. To address these issues and to improve the use of the support, LKAB initiated a project with the aim to study the interaction between their rock support system and the rock.
Aim: Identify important parameters involved in the interaction between shotcrete and rock and if necessary investigate important quantities of these parameters. To improve the understanding of the interaction of shotcrete and rock.
Approach: To achieve the first objective a number of laboratory and field tests will be carried out. The second objective will be achieved by conducting numerical analyses.
