Figure 1. The way of dividing a seam into panels and extraction sequence
Jerzy Kicki, Jacek Sobczyk · 2004
The mining section in which extraction of a thick and steep-dipping seam is to take place should be developed from the main level by means of a crosscut, from which a raise is to be driven on the seam’s footwall. The raise is the main development drive and should be connected to the ventilation system of the area.
