Hästar vid Falu Gruva : 1540-1815Grein, Judit January 2017 (has links)
Falu Gruvas hästar har historiskt sett varit av stor betydelse för det dagliga arbetet vid gruvan. De användes ovan jord för transport av bland annat ved och malm, men även för att driva de många hästvindar som från och med 1540-talet användes för uppfordring samt för att pumpa upp grundvatten ur gruvan. Mellan 1697 och 1815 arbetade även hästar under jord med att driva hästvindar samt frakta malm. Dessa hästar hissades till en början ned i gruvan genom schakten dagligen, men fick sedan bo nere i gruvan där de kom att tillbringa merparten av sina liv. Uppsatsen ger en bred bild av flertalet aspekter av hästarnas liv, med fokus på tiden 1540 till 1815 då hästarna var som viktigast för att hålla igång gruvdriften. Trots hästarnas framstående roll i gruvans historia har de aldrig haft någon framträdande roll i historieskrivningen. Denna uppsats syftar till att skildra Falu Gruvas historia med hästen i fokus. / Falu mine horses have historically been of great importance for the daily work at the mine. They were used above ground for the transportation of for example wood and ore, but also to power the many horse capstans that were used for hoisting and for pumping groundwater out of the mine. Between 1697 and 1815 horses began to work underground as well, with running horse capstans and with transportation. At first, these horses were lowered to the bottom of the mine every day, but later they came to live below ground. This study gives a broad picture of several aspects of the horse's life, focusing on the period from 1540 to 1815, when the horses were very important to the mine. Despite the horses' prominent role in the mine's history, they have never fully been portrayed in historiography. This study aims to do that.

Modeling of experimental studies of fluid and particle transport in porous mediaHärlin Lennermark, Mikael January 2009 (has links)
<p>To extract metals and increase the pH value of water around a historical mine waste deposit a series of barrels are used. Polluted water is forced to pass inside these barrels where different filter materials purify the water. This research project is carried out in Sweden by MTM at Örebro University and Bergkraft in Kopparberg, titled “Methods for characterisation and remediation of historical mine waste”.</p><p> </p><p>The fluid flow trough the filter materials in the barrels are needed to be understood, in order to improve the extracting process.</p><p> </p><p>In this work a small transparent model filled with sand was made to visualise the fluid flow. In that model coloured water is representing the polluted water. To describe the flow in the transparent model a mathematical model is presented. The theory used in this work is the complex variable method in fluid dynamics together with numerical methods and computer programming. There is a pretty good match between the theoretical and experimental results presented in two dimensions. Continuing work could result in a three dimensional model with different geometries using the same technique.</p>

To extract metals and increase the pH value of water around a historical mine waste deposit a series of barrels are used. Polluted water is forced to pass inside these barrels where different filter materials purify the water. This research project is carried out in Sweden by MTM at Örebro University and Bergkraft in Kopparberg, titled “Methods for characterisation and remediation of historical mine waste”. The fluid flow trough the filter materials in the barrels are needed to be understood, in order to improve the extracting process. In this work a small transparent model filled with sand was made to visualise the fluid flow. In that model coloured water is representing the polluted water. To describe the flow in the transparent model a mathematical model is presented. The theory used in this work is the complex variable method in fluid dynamics together with numerical methods and computer programming.
