Abstract

The invention relates to a device for excavating a mined-out area in a foundation (in combination with Figure 1), comprising at least one excavating tool for loosening the rock or soil mass of the surface to be removed of the mined-out area to be established, the at least one digging tool for loosening the rock is arranged on at least one swing arm (21) that can be moved relative to the surface, and the device has at least one microwave device (30) for generating and outputting microwaves into the rock of the surface, the microwave device has at least one applicator (36) for introducing microwaves into the rock, and the at least one applicator can be moved relative to the surface to be removed independently of the situation of the digging tool relative to the surface, characterized in that the at least one applicator is connected to a movement element (31), the movement element can be moved on a guide device (15) such that the at least one applicator can be moved around the digging tool on the guide device independently of the movement of the digging tool.
