  • TOP CAVING – Mining Science and Technology

    Longwall Topcoal Caving (TCC) is a method of extraction for underground mining of thick seams. It uses a longwall set-up and natural forces to aid in the winning of coal. With this method of extraction only a single longwall is developed at the foot of the seam. The control of the roof layers at the face is by means of powered supports.
