Dynamic testing of full rock support systems for underground mines

Purpose and goal:

The purpose is to investigate the prerequisites for starting a full-scale project to build a test facility for dynamic testing of full rock support systems. The objective is to have a result supporting a decision on the start of such a project. The project has largely been able to execute and deliver results according to plan. 100% target fulfillment is expected Q1, 2023 when remaining activities are completed as below:

Budget and time plan for establishing the test facility Costs and time for performing tests in the facility Project plan for building the facility in a subsequent project Expected results and effects:

The pre-study will generate results that describe the prerequisites for and create a basis for deciding on the start of a full-scale project where we build a test facility for complete rock reinforcement systems. We see a large need for this type of testing facility from mines, manufacturers of rock reinforcement, as well as academia and expect to be able to continue working on realizing the planned facility in a new project.

Approach and implementation: The project has been organized and implemented in six work packages, with Swerim and LTU as the main executors: WP 1, Project coordination WP 2, Investigate and define the load cases and failure mechanisms for rock support systems in underground mines WP 3, State of the art analysis - Dynamic testing of full rock support systems

WP 4, Develop test set-up to represent the selected load cases WP 5, Budget and time schedule for establishing the test facility WP 6, Estimate costs for performing tests in the facility WP 7, Develop a project plan for the subsequent full-scale project
