Abstract
The Ashanti Goldfields Corporation (Ghana) Limited is currently undergoing a major expansion programme. Part of this programme is to sink a 6.41m diameter shaft to a depth of 1,037m through 30.5m of water bearing decamposed Birimian phyllites. This paper discusses the plans for the site investigation, the engineering properties of the decamposed phyllite and field permeability tests to establish the bulk permeability of the ground within the vicinity of the shaft. The dewatering well design and the problems encountered during the wells installation and development are also presented.
