Analogue Simulation for Overlying Strata Movement Rule in Full-mechanized Caving Mining Shallow Buried Thick Coal-seam

In order to obtain overlying strata movement rule of full-mechanized caving mining shallow buried thick coal-seam in a mine,western area of China,analogue simulation was made to analyzing it from different conditions.Results obtained first cave and periodical cave pace of basic roof,cave form of overlying strata,three-zone characteristics and strata displacement characteristic,which provided reference for safe mining of coal-seam with similar geological condition.
