recommendations! Published in 2020 at "Rock Mechanics and Rock Engineering"

DOI: 10.1007/s00603-020-02173-5

Abstract: Deep and high-stress mining relies on backfilling the minedout voids to support the surrounding host rock and mitigate rockburst risk. Rational engineering design requires quantifying stress transfer from the host rock to the backfill as… read more here.
