Surface prediction of mining-keeping-backfilling method

摘要

Mining-keeping-backfilling method is a new propped strata movement control method.The mechanism is far different form strip mining and full goaf backfilling.For the prediction precision of Mining-keeping-backfilling method induced surface movement and deformation, this paper use numerical simulate results make regression analysis, and get the probability integral method parameter formula between roof fall collapse mining method and Mining-keeping-backfilling method.It gives method to predict the mining influence and reference for the mining scheme design.
