چکیده انگلیسی

Based upon characteristic movement features of the overlying strata in solid backfill mining and in-situ observations, an associated model representing a roadway support system has been developed. Based on the Winkler foundation and beam model, the current study presents a static analysis of the model, thus permitting acquisition of a theoretical formula pertaining to roof convergence. Through use of working face 6304-1 (Jisan Colliery) as the research setting, the association between roof convergence magnitude and both packwall strength and width have been elucidated. Based upon observed conditions at the working face, realistic packwall parameters have been formulated, with numerical simulation results and field application results indicating that design parameters garnered from the developed formula successfully adapted to local geological movement and deformation. Accordingly, roadway deformation was shown to be within the permissible range, thus satisfying mine production requirements. The proposed method in the current study may give a design basis for pack design in the context of SBM under similar conditions.
