摘要

A method of backfilling excavations, in particular in coal mining, with a backfilling material having a dense structure in the final state and short-term, high compaction, the backfilling in a working direction being effected gradually in individual sections, and residue and waste materials preferably being added to the backfilling material, in which the backfilling with backfilling material in a direction approximately transversely to the working direction - transverse direction - likewise being effected in individual sections, likewise preferably gradually. The subject matter of the invention is also a device for backfilling appropriate excavations, in which each goaf wall section (2) is of U-shaped configuration in cross-section and encloses a goaf space section (14) open on the goaf side and narrowing at least partly in the return direction - working direction - and the free ends of adjacent goaf wall sections bear against one another in a sliding manner at least over the step length of the stope support (3).
