1) top coal movement
顶煤位移
1.
Based on the study of the top coal movement of top coal caving faces and the analysis of the producing and developing of top coal fractures, top coal can be divided into different regions on the basis of fracture character with on the spot bearing pressure curve, top coal movement curve and movement rate curve.
通过对放顶煤工作面顶煤位移的实测研究及顶煤裂隙发生发展的理论分析，利用实测的支撑压力曲线、顶煤位移曲线和位移速度曲线，按裂隙性质对顶煤进行分区，针对不同特点的分区，提出了利用裂隙性质改变现行注水范围、钻孔布置方式的新方法。
2) Track of top-coal moving
顶煤位移轨迹
3) Top-coal movement
顶煤运移
5) top displacement
顶点位移
1.
Design based on top displacement of confined boundary zones in a tall shear wall structure
某高层剪力墙约束边缘构件基于顶点位移的设计
2.
With the help of the software ANSYS,this article calculated shear wall top displacement under different transverse load,thus calculated shear wall equivalent stiffness under the conditions of the corresponding load in accordance with design requirements,providing a new way for calculation of equivalent stiffness of the open-cross shear wall.
利用商用程序ANSYS计算不同横向荷载作用下剪力墙顶点位移,从而根据设计需求计算相应荷载工况下剪力墙等效刚度,为规则和非规则开洞剪力墙的等效刚度的计算提供了一种新途径。
6) up displacement
上顶位移
补充资料：综采放顶煤
综采放顶煤：厚煤层煤炭开采技术之一。把原来分层开采的煤炭，一次采完。方法是，在煤层底部按传统方法开采，使上面的煤炭在矿压的作用下，自动落下来。
