中文摘要：

建立地表移动观测线是求取开采沉陷岩层移动参数的重要途径,鉴于某矿地表3211观测线的布设不严格平行于工作面走向或倾向方向,通过分析该观测站的实测资料,确定了沿观测线布设方向的斜向移动角;根据斜向移动角和移动角的空间关系,推算出了该矿区的岩层移动角.研究表明,基于空间关系推算岩层移动角的方法简洁实用,能够满足开采沉陷工程的实际要求.

英文摘要：

The important way of determining strata movement parameters is to establish a mining subsidence observation line.Considering that the ground observation line 3211 is not laid out strictly parallel to the trend or the tendency direction of the coal face,the angle of oblique critical deformation along the observation line layout direction is determined by the analysis of the observed data.According to the spatial relation between the angle of oblique critical deformation and the angle of critical deformation,the strata movement angle is calculated.The research shows that the calculation of the strata movement angle based on the spatial relationship is simple and practical,and can meet the practical requirements of mining subsidence engineering.
