Development of underground mining techniques for extremely rich uranium deposits

Mining techniques for rich, deep uranium deposits are reviewed in which common techniques cannot be applied owing to the high radioactivity and poor mining conditions. The investigations are carried out on a model deposit based on data of the Athabasca uranium deposits in Saskatchewan, Canada. The deposit geology, planning parameters, bedrock stabilisation and supporting, mining techniques, the development of the mine layout, the underground infrastructure, and the choice of mining methods are gone into. The descriptions are not detailed enough to serve as a basis for planning. (DG)
