| Abstract: | Based on practical falling and filling condition of mined-out area in the steep seam and taking the caved debris filled in lower goaf as elastic foundation, the mechanical models of elastic foundation wall are founded. Using theoretical analysis and simulating experiments, the effects of height and strength of filling debris on breaking regularity of roof-rockwall along incline and rock pressure manifestation in working face are studied. |
