1. 1. Installation of cables for monitoring purposes in the ground by using Horizontal Directional Drilling

   University essay from Lunds universitet/Teknisk geologi; Lunds universitet/Väg- och vattenbyggnad (CI)

   Author : Eduardo Garcia Cañas; [2022]
   Keywords : HDD; Earth Embankment Dam; Resistivity; ERT; IP; Technology and Engineering;

   Abstract : The median age for Swedish earth embankment dams is about 60 years. Due to its longevity, one of the major concerns is the internal erosion causing increased seepage through the dam, which ultimately may increases the risk for dam failure. To meet this challenge, there is a need for improved monitoring methods. READ MORE

3. 2. Evaluation of Models and Optimisation Methods for Energy Minimisation of Drill Riggs

   University essay from Linköpings universitet/Fordonssystem

   Author : Mohamed Faraj; Max Olsson; [2022]
   Keywords : Vehicle Propulsion Systems; Electrical powertrain; Modeling; Simulation; Deterministic dynamic programming; AMESim;

   Abstract : There are many benefits from using electrical powertrains over diesel powertrains within the mining industries, where some of these benefits come from reducing the pollution within the mines and therefore improve the working environment as well as reduce the ventilation costs required from ventilating these pollution. It is also desired to optimise the use of the vehicle to increase the efficiency and reduce fuel consumption of the vehicle. READ MORE

4. 3. Development and application of a tool for assessing the impact of failure modes on performance of underground drill rigs.

   University essay from Örebro universitet/Institutionen för naturvetenskap och teknik

   Author : Rickard Larsson; [2021]
   Keywords : availability; functional contracts; failure modes; discrete event simulation; mining; drilling rigs; tillgänglighet; funktionella kontrakt; feltillstånd; diskret händelsestyrd simulering; gruvdrift; borriggar;

   Abstract : Trends such as increasing awareness of sustainable production, shorter product life cycles and personalised products create challenges for the mining industry. A solution to these challenges may be a functional product business model, where the provider sells the hardware’s function under a service contract and is responsible for delivering the combination of hardware and services over the duration of the contract.

5. 4. Developing a drill boom attachment to extract iron ore in a new mining system

   University essay from Karlstads universitet

   Author : Niklas Berntsson; [2021]
   Keywords : ;

   Abstract : The modern product development technique led this bachelor thesis forward with structure and finesse by using the Double Diamond theory. The bachelor thesis was carried out in collaboration with LKAB and NECAB with the aim of develop and design a two-parted mechanical attachment for their new mining system. READ MORE

6. 5. Evaluation of SCPT-surveys as method for accessing dynamic modulus

   University essay from Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

   Author : Joakim Granskär; [2018]
   Keywords : SCPT; Dynamic modulus; Seismic surveys;

   Abstract : The purpose of this master thesis is to evaluate the results from the completed SCPT (Seismic Cone Penetration Test) surveys with respect to the methods ability to estimate dynamic young´s modulus. This has been done by comparing the result from SCPT to other seismic methods and dynamic parameters converted from “static” geotechnical surveys. READ MORE
