An experimental study of ice-bed separation during glacial sliding...size.A laboratory ring-shear device allows sliding and ice-bed separation to be studied experimentally....
Mining-induced movement properties and fissure time-space evolution law in overlying strata... The results show that bed separation fissure and vertical fissure will appear in the overlying strata above mining face, which form the wedge-shaped fissure zone....
Analysis of overlying strata movement and disaster-causing effects of coal mining face under the action of hard thick magmatic rockWhen the hard and thick key strata are located above the working face, the bed separation structure is easy to be formed after mining because of the high strength and integrity of the hard and thick key strata and the initial breaking step is large....
Research on preventive technologies for bed-separation water hazard in china coal minesAbstract Bed-separation water is one of the major water hazards in coal mines....
