Abstract :The characteristics of overburden strata structural features of typical shallow seam with thin bedrock in Shandong mining area is: there is only one key stratum which controls the overburden strata movement insert ignore into journalissuearticles values(main roof);, when the thickness of bedrock is smaller insert ignore into journalissuearticles values(generally less than 50-60 m); and the key stratum located under the fissure zone or inside the caving zone through the analysis combined geological data Shandong mining area with the experience in mining practice for a long time. Strata behavior is comparatively fiercer in mining process and it’s easy to lose phreatic water and surface water resource
Keywords : linked fracture of shoal, shallow seam, caving zone, Shandong mining
