The soil loosened at the fron when heading is returned to the pressing pit and must be removed here and disposed.
The viscous concentrated soil could be sucked off ba a KTZ pump with "suction hat" (reversed inlet strainer).
The specific advantage was the operation of the pump which could be used also during pressing. Transporting off was simple as it was possible to pump the drilling material directly into the containers provided.
No tank truck was necessary.
