Progress of fully mechanized mining with solid backfilling technology
Abstract：On the basis of a brief overview of mining with backfilling history and the objectives, requirements and diffi- culties of developing modern mining with backfilling technology, this paper systematically introduced the research pro- gress of fully mechanized mining with solid backfilling technology, focused on the expounding the strata movement the- ory of mining with dense backfilling,including equivalent mining height theory of strata movement control, continuous media mechanics model of strata movement, calculation formula of strata movement, and stope rock pressure and sup- port stress analysis, which are the prerequisites of the new technology. And then detailedly introduced the sys- tem, equipments and technics of fully mechanized mining with solid backfilling technology, and the engineering exam- ples of large-scale mining with backfilling under dense buildings, island village coal pillar, near the loosen aquifer and under the large embankment.
