Underhand stoping is a method of extraction starting at the surface and continuing downwards. It is the oldest extraction technique for mining seams of ore. The underhand stopes at Ehrenfriedersdorf focus on the seams known as the Einigkeit (or Unity) seam and the Leimgrüben seam. The seams run almost parallel to one another from north to south. To the east of these stopes is the Prinzler underhand stope. The Einigkeit stope has been made partially accessible to visitors and the coe has been reconstructed. The stopes have been backfilled using spoil from mining activities.
