摘要
According to the invention, to collect the fine rock material coming through the fissure coverings, there are arranged on the fissure coverings collecting channels which reach under the fissures and extend in the longitudinal direction of the fissures so that rock material passing through falls directly into the collecting channels. Emptying of the collecting channels can take place e.g. by means of rinsing with water or even in a mechanical manner.
