Stull Stoping

An underground hardrock mining method that uses systematic or random timbering (stulls) placed between the foot and hanging wall of the vein. This method require that the hanging wall and often the footwall be of competent rock as the stull provide the only artifical support. These type of stopes have been used up to a depth of 3,500 and in stopes up to 12 feet wide.
