本文是根据抚顺矿区多年来的岩层移动观测资料编写的.用相关分析的方法和最小二乘法原理,解出了在倾斜特厚煤层水砂充填开采条件下的下山岩层移动角、边缘角、破坏角和最大下沉角与煤层倾角的线性方程式. 求算这些角值的方程式,可供在相同地质采矿条件下或类似此条件的新矿区参考. This paper is based on the observation data of rock movement during the past years in Fushun Mining Area.According to the correlation analysis method and least square method, the displacement angle, Angular and maximum subsidence angle and coal seam inclination Equation for calculating these angle values ​​is available for reference to new mines under the same conditions of geological mining or similar conditions.
