摘　　要：通过对浅埋薄煤层1601综采工作面的矿压实测研究,分析了其矿压显现特征及来压规律,评价了支架对工作面的适应性。结果表明:工作面周期来压动载系数平均为1.29,动压不明显;工作面中部支架平均工作阻力比上下两端头大,符合开口向下的抛物线关系;支架平时载荷和来压期间载荷均未超过支架的额定工作阻力,支架适应性良好。Based on the strata behavior regularity learned in a study program on#1601fully-mechanized longwall face in a shallow thin coal seam,the characteristics of strata behavior and weighing regularity are analyzed in detail and the adaptability of powered supports to the working face is also assessed.The result shows that the#1601fully-mechanized longwall face＇s dynamic load coefficient of periodic weighing is averaged at 1.29while its dynamic load is not significant.The average working resistance of the powered supports in the middle part of the working face is bigger than those at both upper and lower ends of the face,which is in accordance with a parabol-ic curve.Either the supports＇load at normal time or weighing time doesn＇t exceed their rated working resistance,and the adaptability of supports is good.
