Current projects
-
Sustainable Quality Drilling
This project will focus on identification of a fundamental setup that is required for transforming MWD data and hole deviation data into sensible design parameters and to integrate them in blast design theories. The project provides an opportunity to develop methodologies that will facilitate the de...

Optimisation of fragmentation and comminution at Boliden Mineral, Aitik Operation
Blasting is one of the main processes of mining and its results have a major impact on the mine's total economy. The result of fragmentation affects not only the mine's productivity and unit costs but also the subsequent processes of crushing and grinding in the mill.

Block Cave Ventilation, Electric Vehicles, and Zero Emission Mining
OZ Minerals is an Australian based mining company focusing on copper. Currently, OZ Minerals is developing a new mine called Carrapateena located in South Australia, approximately 460 km north of the State capital Adelaide. Carrapateena will initially use Sublevel Caving (SLC) as the mining method b...

MiReBooks: Mixed Reality Handbooks for Mining Education
MiReBooks produces a series of Virtual and Augmented Reality based (=Mixed Reality MR) interactive mining handbooks as a new digital standard for higher mining education across Europe. Many current challenges in mining education will be met in an innovative new way, by combining classical paper base...

IlluMINEation
The European project IlluMINEation, funded by the European Commission within the Horizon2020 Programme has recently been launched. The EU-funded illuMINEation project will highlight significant aspects of the digitalisation in underground mining.

Numerical modelling of blast-induced damage around rock tunnel using LS-DYNA
The overall goal is to develop a reliable numerical modelling process to predict blast-induced cracks in the tunnel wall and floor based on small-scale tests and earlier field investigations and then optimize the blast design of perimeter hole blasting.

New major EU project on sustainable mining
Luleå University of Technology is the only Swedish university that participates in a new large project on autonomous carbon neutral sustainable mining. In EU-funded NEXGEN SIMS, technology, methods and processes that will enable a more sustainable and efficient carbon neutral mining operation will b...

Numerical investigation on impacts of blast-hole deviation on fragmentation
The accurate drilling of holes is essential for a good blast performance. However, the blast-hole deviation is frequently experienced in mine as the bit advance deep into the rock mass.

Stress changes in underground mines - from theoretical investigation to practical recommendations
Stress changes due to underground mining are the main cause for mining-induced seismic events. These events can cause damage in the rock and mine infrastructure and even casualties and lead to long-term closure of large mine areas. Although the stress changes are important factor, currently there ar...

Destressing strategies for mining under highly stressed conditions in the deep mines of Sweden
The overall aim of this project is to explore and develop destressing strategies that allow mining engineers to mitigate rockburst risk and deformation potential of rock under highly stressed conditions in the deep mines of Sweden.
-
Augmented rock mechanics reality in underground mining
The mines extracts ore at an increasing depth. This means that the stresses increase, which in turn leads to a more unsafe work environment. Augmented reality (AR) is a technology where you can enhance (or augment) the real-world view with the help of computer-generated information. AR is thus a tec...

Evaluation of the limits of empirical stability graph method (SGM) for Swedish underground mines
Stoping-based mining methods (e.g. sub-level stoping) have been used in Swedish mines, such as Zinkgruvan mine, Garpenberg mine due to high rate of production and stability after backfilling. However, there are a number of challenges with this mining method, such as dilution due to instability of th...
