摘　　要：通过对大柳塔22614薄基岩浅埋深综采工作面的矿压实测研究,对其矿压显现特征及来压规律进行了详细的分析,并对支架对工作面的适应性做了评价。得出如下结论:周期来压步距随基岩厚度增大而增大,来压强度随基岩厚度增大而减小,基岩变厚区比基岩变薄区来压步距大、来压强度大,9000kN支架基本符合该工作面开采要求等。The strata behavior measured regularity of 22614 fully-mechanized face of Daliuta in shallow coal seam with thin bedrock is and weighting regularity are analyzed in studied, and then its characteristics of strata behavior detail, the adaptability of supports to working face is appraised.The conclusions are drawn as follows：the periodic weighting length increases with bedrock thickness, the cycle weighting strength decreases with the bedrock thickness,the periodic weighting length and cycle weighting strength of bedrock thickness ascending region are larger than decreasing.9000kN hydraulic supports basically meet the requirements of the fully-mechanized face.
