A tracer test developed for hydrodynamic investigations has been successfully tested in German underground mines and the results of one of those tests are reported on here. The objectives of the test were to investigate the kind and rate of flow within a flooded mine. At each sampling point, coloured spores were injected using a Lycopodium apparatus. Beginning one day after injection, two samples were collected per weekday at each sampling point. A considerably good recovery rate of 2% was obtained. The mean velocity of the mine water within the investigated part of the mine was 2.6 m min−1 and the different parts of the mine proved to be hydraulically well connected with each other. It appears that the hydrodynamic system within the flooded mine is dominated by convective flow from deeper parts of the mine to higher ones. [ABSTRACT FROM AUTHOR] |
