Abstract (en)

The present disclosure relates to a device and a method for measuring the course of a longwall mining installation (1) extending along a longwall face (2). A movable course measuring device (30) comprises a first segment (40) extending along a first axis (B), a second segment (42) extending along a second axis (C). The second segment (42) may be movably connected to the first segment (40). The course measuring device (30) may further comprise a course measuring unit (46) for measuring a spacial relationship between the first axis (B) and the second axis (C). Based on measurements of the movable course measuring device (30), it may be possible to determine a polygonal course of the longwall mining installation along the longwall face (2).
