摘要
The method is for extracting minerals from deep mines or quarries. The roof of the mine gallery is supported by means of a number of panels (Dp) (Dp + 1) (Dp + 2) etc. Each panel is independently supported by supports (P). The mineral is then removed from the floor of the gallery so that the gallery roof is allowed to cave in area by area corresponding to the area of a panel (Dp) (Dp + 1) (Dp + 2) etc.
