Developed measurement approach for mining applications

Purpose and goal:

Mining undergoes a paradigm shift from manually obtaining information to automatically obtaining information for planning and streamlining processes in underground mining.

An efficient drilling process rely on sensors and measuring equipment which provide the operator with a basis for decisions. The objective of this project is to investigate the improvement potential and applicability of new technology for quality measurement in the drilling process. This has been fulfilled through a proof of value study where the technology is partially integrated into today´s work process.

Expected results and effects:

The project started with a knowledge gathering phase, assessing the value which hole quality measurement can add to the mining process. The value is found to be large for those cases where you have recurring problems with the blasting result, usually due to inappropriate rock size distribution. In the project, Epiroc performed tests together with a technology supplier to evaluate available technology for hole deviation measurement.

A number of adaptation needs have been identified and a demonstration prototype has been produced which has also been tested in Epiroc´s test mine. Approach and implementation: The project was carried out in three phases:

1. Knowledge gathering regarding value and area of use; This phase consisted of interviews, workshops, analysis of today´s solutions and shortcomings as well as a shorter concept study of the potential for improvement.

2. Demonstration prototype; This phase consisted of the creation of a physical demonstrator that demonstrates the applicability of key features that improve quality monitoring in the drill and blast process. 3. Reporting of results and description of continued need for technology and method development.
