Analysis on Strata Behaviors Laws of Thin Coal Zones in Liangbei Coal Mine

Taking 11061 island mining face in Liangbei coal mine as the research object,the datum of hydraulic supports and EMR during the thin seam transition period are used to summarize the mine pressure behave laws and variation characteristics before and after encountering thin coal seam,and the reason of the anomaly is analyzed.Meanwhile,the paper formulates targeted prevention and control measures to provide data support for the safety production in coal mines.
