Geokemisk undersökning vid Rävlidmyrgruvan, Västerbottens län : provtagning, analys och förslag till åtgärder

The mining industry, in terms of ore excavation and metal production, is and has been important to the Swedish economy. In connection with the ore excavation process, large amounts of partly sulphidic waste are produced. When the metal sulphides are exposed to air and water they are eventually oxidised, which leads to the formation of acidic water with high concentrations of metal cations and sulphate ions, so called Acid Mine Drainage (AMD). This water may reach the nearest surroundings and cause negative environmental effects. By covering the waste with soil or water, the oxidation process can be minimised. At the Rävlidmyran Mine in the county of Västerbotten open pit mining took place between 1951 and 1991.

Förmågan till minröjning, en verklighet för framtidens jägargrupp : Ökad förmåga till problemlösning i dagens konfliktområden

I dagens konfliktområden är förekomsten av minor och oexploderad ammunition(OXA) ett vanligt förekommande problem för civilbefolkning samt de militära enheter som arbetar i området för att skapa stabilitet och säkerhet. Den här uppsatsen avhandlar möjligheten att lösa eventuella problem som har att göra med förekomsten av minor och OXA i ett missionsområde utan tillgång till stödresurser i form av min- och ammunitionsröjningsteam. Uppsatsens syfte är att undersöka om det är möjligt att tillföra minröjningskompetens på gruppnivå utan att tappa ursprunglig kompetens och fokus från huvudtjänsten. Uppsatsen tar även upp vilken lägsta nivå av utbildning som krävs för att kunna röja Mineringar och OXA, samt hur man når upp till det målet. Uppsatsens frågeställning har varit: Går det att inom ramen för Jägarbataljon 09 utbilda en soldat som besitter kompetensen att kunna identifiera och röja Mineringar samt OXA? Om ja, vilken utrustning bör tillföras? Mina slutsatser är att det är praktiskt möjligt genom att tillföra en min- och amröjledare på bataljons nivå.

Scenografi till Batboy - the musical

This is the project of making a stage design for Batboy ? the musical, a cooporation with a network of musical artists. The aim of the project was to create a space on stage that strengthens and expands the experience of the story told, and find design solutions that give an extra dimension to the story. The prerequisites for my work were partly defined from the produc¬tion, as were my limitations. In the cast of ten artists some were to play more than one role, often one of the opposite sex.

Landvinning : scenarier för efterbehandling och gestaltning av Aitikgruvan, Gällivare

Open pit mining creates huge amounts of tailings and waste rock deposits. Due to it's content of sulphide Minerals, predominantly pyrite (FeS2), there is a risk of oxidation and formation of acid water containing heavy metals, known as Acid Rock Drainage (ARD). To prevent the process of oxidation, the tailings and waste rock have to be reclaimed. The most commonly used methods of reclamation are a coverage of water or soil. Mining also results in a large-scale interference in the landscape that will make an eternal change of its appearance.

Trycksättning och dimensionering av brandhiss för berganläggning

This thesis deals with the design of a combinated rescue-, personal-, and firefighting elevator for a nuclear waste storage facility to be constructed by the client SKB, Svensk Kärnbränslehantering AB. SKB:s mission is to dispose of all nuclear waste from all swedish nuclear power plants. The storage facility will be built in the rock 450 m under the surface and will consist of several kilometers of tunnel where capsules containing the nuclear waste will be placed. It will also hold a central area which contains spaces necessary for the operation and construction of the facility, such as elevator hall, storage hall etc. The facility will have two ways of access: a vehicle ramp and an elevator shaft.

Kemisk stabilisering av gruvavfall från Ljusnarsbergsfältet med mesakalk och avloppsslam

Mine waste from Ljusnarsbergsfältet in Kopparberg, Sweden, is considered to constitute a great risk for human health and the surrounding environment. Some of the waste rock consists of sulphide Minerals. When sulphide Minerals come into contact with dissolved oxygen and precipitation, oxidation may occur resulting in acid Mine drainage (AMD) and the release of heavy metals. The purpose of this study has been to characterise the waste material and try to chemically stabilize the waste rock with a mixture of sewage sludge and calcium carbonate. The drawback of using organic matter is the risk that dissolved organic matter can act as a complexing agent for heavy metals and in this way increase their mobility.

Grundvattnets geokemi vid Gladhammars gruvfält, Västervik. Effekter av äldre tiders kobolt- och kopparbrytning

The municipality of Västervik, with support from Envipro Miljöteknik AB, is carrying out a main study of the Minefields at Gladhammar. Mining of iron, copper and cobalt under different periods from the 16th century until the end of the 19th century has led to discharges of metals to the lakes situated downstream. The aim of the main study is to investigate the possibilities to reduce the environmental load on the surrounding ground and water caused by heavy metals from the Mine. The present report is a part of the main study. The aim of the work is to investigate the geochemistry of the groundwater.

En intuitiv & lättillgänglig flyktmask för gruvmiljö

I have always lived around Mines and around people work­ing with Mines. They are a natural part of my life and, inev­itably, a great interest of Mine. When time came to make a decision for a degree project, focusing on the Mine context felt as natural as breathing.In LKABs underground Mines, safety in fire accidents is a great priority. Of outmost importance for the escape is to have a personal gas filter for filtration of smoke and/or gas. My design project resulted in a concept which is aimed at shortening the user journey from the start of the accident until the user has applied the personal safety solution and is ready to escape.Throughout the project I?ve been working with a context which is heavily regulated, and all problems are serious, important ones.

If the choice was mine, what would I want? Continued management development within Social Services.

Svenskt abstract: Denna uppsats syftar till att undersöka och belysa vad enhetschefer på en socialförvaltning efterfrågar för kompetensutveckling avseende sin personal, samt deras förhållningssätt gentemot kompetensutvecklingars innehåll och utförare. Jag vill med denna uppsats belysa enhetschefernas attityder till, och kunskap om, olika typer av kompetensutveckling för sin personal. Detta görs med hjälp av intervjuer med enhetschefer och förklaras utifrån organisationsteori med inriktning på ett instrumentellt perspektiv. Resultat i denna uppsats visar att det enhetscheferna efterfrågar är beroende av hur organisationsstrukturen är utformad, vilken kompetens som finns idag och vilken kompetens som fattas i organisationen.

Datorsimulering av gruvlastare för funktionell testning

I denna rapport presenteras hur en simulatorlösning för funktionstestning av en gruvmaskin har tagits fram. Arbetet har skett i Atlas Copcos regi och består av tre delar: kartläggning i form av intervjuer, utvärdering av befintliga simulatoralternativ och slutligen val och implementation av lösning. Resultatet visar på en konceptuell prototyp, där en gruvmaskin visualiseras i en 3D-miljö tillsammans med en virtuell gruvgång. Detta möjliggör bland annat testning av autonom navigering, alltså att en gruvmaskin självständigt styr utifrån avläsning av tunnelväggar med hjälp av laser. Samtidigt tillåter lösningen också att kontrollvärden från olika sensorer, såsom vinkelgivare, kan hämtas ut ur simuleringen..

Ett förlorat bröst : En systematisk litteraturstudie om kvinnors erfarenheter av kroppsuppfattning och sexualitet till följd av mastektomi

The purpose of this study was to investigate how the adult world is produced in the books of Martin Widmark about LasseMajas detektivbyrå from a gender perspective.I wanted to answer questions concerning the appearance, personal characteristics, occupations and activities, and the relationship between children and adults to do my analysis.I decided to make a qualitative content analysis to answer my questions.I used the gender theories that describe how stereotypes excel. I related these gender theories to the books that I have studied.I also used previous research on gender roles in other children's books to compare their results with Mine.After reading, analyzing and comparing the books I have come to the conclusion that gender roles in books about LasseMajas detektivbyrå is very gender stereotyped..

Mikroskopering av opaka faser - en studie från Skyttgruvan, Falun.

In nature there are about 4,500 Minerals identified. These can roughly be divided into two groups, opaque phases and non-opaque phases, with the exception that some opaque phases also may act as a non-opaque phase in different circumstances. The division is made on the basis of the optical properties. Opaque phases are nontransparent, which means that a different type of microscope must be used. A conventional microscope uses transmitted light while the microscope for opaque phases or the ore microscope uses reflected light.

Mining for culture : performance arts center Ställberg?s Mine

This degree project summarizes five years of education at the landscape architecture program at the Swedish University of Agriculture Sciences, SLU, Alnarp and the School of architecture at Royal Institute of Technology, KTH, Stockholm. The project has been carried out by Lovisa Berg and Per Crona in collaboration with DRIFT Scenkonst. This master project is based on the ongoing transformation of a former mining site in Ställberg, Bergslagen situated in central Sweden. The organization DRIFT is in the process of recreating to former industrial mining site as a green cultural center. Their field of artistic examination concerns existential questions connected to the site. The aim is to offer a place for both performing and experiencing contemporary performing arts in Bergslagen. Our objective is to contribute to the growth of the performing arts project and to demonstrate in concrete terms how a conversion of a mining area can be completed, while taking into account both its history and its new function.
