Spatiotemporal Synergetic Control of Roof Stability in Longwall Paste Backfill Mining: An Analytical Model Considering Time-Varying Backfill Characteristics

To address the difficulty of roof control in longwall paste backfill mining and to better capture the backfill’s ‘sequential bearing’ effect, this study proposes an elastic foundation beam model. Based on the Gaohe Coal Mine, the “coal-support-backfill” model incorporates the tim...
