  1. 1. Mineral Rights : Legal Systems Governing Exploration and Exploitation

    Författare :Eva Liedholm Johnson; Hans Mattsson; Barbro Julstad Julstad; Kauko Viitanen; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mineral Rights; mineral legislation; exploration permit; claim; exploitation- mining concession; lease; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur;

    Sammanfattning : The objective of this thesis is to examine the legal procedures and systems concerning granting or possessing mineral rights, and how such rights may be exercised, particularly given the diametric interests of land use, ownership and land tenure. The study, comparative in its nature, aims at highlighting the similarities and differences between the countries and states of comparison, and thereby identify interesting solutions of issues relating to the granting and exercising of mineral rights.

  3. 2. Seismic Exploration Solutions for Deep-Targeting Metallic Mineral Deposits : From high-fold 2D to sparse 3D, and deep-learning workflows

    Författare :Magdalena Markovic; Alireza Malehmir; Gilles Bellefleur; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Exploration; Seismic; Mineral Deposits; Diffraction; Deep learning;

    Sammanfattning : Mineral exploration has in recent years moved its focus to greater depths than ever before, particularly in brown fields. Exploring new deposits at depth, if economical, would not only expand the life of mine but also provide minimal environmental impacts. It allows the existing mining infrastructures to be used for a longer period. LÄS MER

  4. 3. A feasibility study of exploration for deep seated ore bodies in the Skellefte field

    Författare :Kerstin Malmqvist; Umeå universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Monte Carlo simulation; deep exploration; massive sulphides;

    Sammanfattning : Simulation technique has been used for a feasibility study of a deep exploration project for massive sulphides in an old mining district, the Skellefte field. The outcome under very different conditions has been studied. LÄS MER

  5. 4. Mining Futures : Predictions and Uncertainty in Swedish Mineral Exploration

    Författare :Tobias Olofsson; Patrik Aspers; Gholamreza Azarian; Trine Pallesen; Uppsala universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Uncertainty; Risk management; Sociology of the Future; Valuation; Justification; Mineral Exploration; Second Nature; Natural Resources; Sociologi; Sociology;

    Sammanfattning : Any forward-oriented enterprise must somehow manage the challenges posed by uncertainty and with its distant temporal horizons, high stakes, and low probability of success, mineral exploration is a good illustration of this general rule. Based on a combination of interviews, observations, and archival research, this thesis investigates how explorationists use predictions to manage the material complexities and the uncertainties that contribute to determining the future minability of mineral deposits.

  7. 5. Innovative seismic imaging solutions : From hardrock mineral exploration to quick-clay site characterization

    Författare :Tatiana Pertuz; Alireza Malehmir; Cesare Comina; Uppsala universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Seismic methods; mineral exploration; quick-clays; seismic imaging; seismic characterization; Geofysik med inriktning mot fasta jordens fysik; Geophysics with specialization in Solid Earth Physics;

    Sammanfattning : Seismic methods are an efficient and powerful tool to explore the subsurface. It principally helps to gain information on the subsurface structure, bedrock topography, and the nature of the host rock. LÄS MER
