ABSTRACT:
When breaking up lumps of stone from a subaqueous stony ground, the lumps are loosened by means of at least one chisel inserted into the ground and being moved along the ground surface. In order to break up lumps of stone by low power and to main a predetermined size of the loosened lumps of stone suitable for being lifted by a suction dredger system, the structure of the top layer of the stony ground is disturbed by inserting displacers from above into the ground at places distributed over the ground surface.
