A video generating method includes acquiring video materials from an initial collection which comprises user-related videos, acquiring a target audio material serving as background music, performing image feature extraction on video frames of each video material, and performing segmentation processing according to image feature information corresponding to each video frame to acquire a target video segment corresponding to the video material, and merging the target video segment and the corresponding target audio material to generate a target video. The target video includes video segments which are obtained based on the target video segments respectively, the video segments in the target video are played in order of post time, and time lengths of the video segments are matched with time lengths of corresponding musical phrases in the target audio material.

A three-level prevention and control method for a rock burst roadway, the method comprising: pre-weakening a thick and hard rock layer above a roadway before the roadway is excavated; carrying out prestress support, pressure relief and reinforcement when the roadway is excavated; and carrying out stress transfer on an advance abutment pressure, and arranging a composite energy absorption protective structure around the roadway before the mining of a working face. By coordinating the spatio-temporal relationship between pressure relief, support and prevention, the energy dissipation in the rock burst roadway is changed from an unstable, disorderly and uncontrollable dissipation state to a stable, orderly and controllable dissipation state.
