Determination of strike and dip and geological cross section12/02/2017 · The dip direction will be in the general direction of the lower elevation. With a high point on the left side, the bed would have to be dipping from the left to right. To draw a dip line, take any point on strike line (CD) and draw a line perpendicular to line CD. So in this case the dip is in the SE direction. 7.

StopingStoping is the process of extracting the desired ore or other mineral from an underground mine, leaving behind an open space known as a stope. Stoping is used when the country rock is sufficiently strong not to collapse into the stope, although in most cases artificial support is also provided.. The earliest forms of stoping were conducted with hand tools or by firesetting; later gunpowder ...
