Repeated mining of shallow-buried close-distance coal seams can disturb the fractured strata remaining in the goaf of the upper coal seam. Under gully terrain, mining disturbance is coupled with surface-relief effects, which may reactivate the overburden structure and induce dynamic strata-pressure behavior. In particu...

Due to the excellent regression performance for semi-supervised learning, semi-supervised support vector machine (S3VR) is introduced for dealing with quantities of unlabeled data in the real world. However, the optimal objective function is not differentiable, which is required to suffer tedious calculation burden and...
