Study on Strata Behavior Law and Support Adaptability in Fault Island Pillar Light Caving Face

According to the geological conditions of coal seam and the specific circumstances of the roof and floor in 2123 fault island pillar light caving face of Shigejie mine, this paper studies strata behavior and fault disturbance in 2123 face. Research results show that weighting features in fault island pillar face under stress concentration are still is periodic weighting, pace distance from 14.5-18m, average 17.1m, but weighting strength is not big, average dynamic load coefficient is 1.23. Supporting parameters of ZFQ2500/16/24 type light fully mechanized top-coal caving support are reasonable and has better adaptability in 2123 fault island pillar face. Analysis and research on strata behavior and control technology of fault island pillar light caving face supply reference for similar mining conditions.
