  1. 11. Rock Strength Testing of Drill Core Samples From Kiirunavaara Below Level 1365

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Giorgios Doulamis; [2022]
    Keywords : Kiirunavaara; Point Load test; Leeb hardness test; intact rock strength; correlation factor;

    Abstract : The geotechnical parameters of the different lithologies are of great importance regarding mining, infrastructures development and safety. The main aims of this thesis project are the evaluation of the previously acquired point load tests (PLT) data and the acquisition of a larger set for the various lithologies and alterations.

  3. 12. Identifying Important Features to Minimize Hole Deviation in Percussive Drilling

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Ketan Dhananjay Deshpande; [2021]
    Keywords : Bending; Buckled profile; Drilling; Hole deviation; Mathematical model; Böjning; Buckled profil; Borrning; Hålavvikelse; Matematisk modell;

    Abstract : Hole deviation is one of the most significant problems in drilling applications. Deviated holes result in inefficient blasting and have severe economic impacts due to increased equipment consumption. Conversely, straighter holes help in increasing production scales and reduce operational costs. READ MORE

  4. 13. Localization of fractures in drill cores using Deep Learning

    University essay from KTH/Skolan för elektroteknik och datavetenskap (EECS)

    Author : Felix Magnell; [2021]
    Keywords : ;

    Abstract : Investigating and assessing rock structures requires extensive manual work, where geologists measure the fractures in drill cores to get a better understanding of the condition of the underlying rock. This study investigates the possibility to use Deep Learning for localizing fractures in images of drill cores, automating and facilitating the work of geologists. READ MORE

  5. 14. A Geometallurgical Approach Towards the Correlation Between Rock Type Mineralogy and Grindability: A case study in Aitik mine, Sweden

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

    Author : Raoul Schmitt; [2021]
    Keywords : Geometallurgy; autogenous grinding; process mineralogy; grindability test; abrasion breakage; automated mineralogy;

    Abstract : Aitik is a large copper porphyry type deposit located in northern Sweden, currently exploited at an annual rate of approximately 45Mt. The ore's exceptionally low head grade of 0.22 % Cu and varying degrees of hardness across the entire deposit pose challenges to the two fully autogenous grinding lines, each of which comprises a 22.

  6. 15. Analysis on how to estimate the number of holes a drill rig has completed based on its activity

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Elias Elfving; [2021]
    Keywords : frequency estimation; mining; drill rig; method analysis; machine learning;

    Abstract : Industrial processes have for a long time become more and more automated, this is no different in the mining industry. When excavating during mining operations special drill rigs are used to drill holes in the rock walls to be used for either explosives or bolts to support the structure. READ MORE
