Main factors for subsidence controlling by backfilling and its influence law
In order to further promote the application of backfilling technology in mining under buildings, water bodies and railways, this paper introduced three types of technology of solid backfilling, paste backfilling, and high water backfilling in coal mines.The influence of main factors on mining subsidence was systematically analyzed,such as: the original stress, the strength of coal seam, roof, and floor; the mining height; the cut width; the backfilling rate, and the strength of backfilling body, compression rate.It studied mining subsidence in backfilling and its three amounts of the roof subsidence, the non-touch-roof amount, and the compression amount.Finally, the paper proposed series of technical measures to improve the effect of subsidence control.
