In several deep and high stress mines, squeezing rock conditions are caused by the presence of foliation and the orientation of the drift with respect to this foliation. This paper relies on field observations from two hard rock mines to support the hypothesis that the angle of the drift walls, with respect to the orientation of the foliation, has a significant influence on the level of squeezing. This study evolved by recognising that, irrespective of the employed support system, it was difficult to maintain open drifts developed subparallel with respect to foliation. This had a direct impact on the required rehabilitation to keep the drifts functional. A database was constructed at the Lapa and LaRonde mines of Agnico-Eagle, recording the observed levels of squeezing for drifts developed at varying angles with regard to foliation.
