该文以新安矿区小浪底水库南岸王家沟一带采空区为原型，进行室内相似模拟实验研究，通过在模拟岩层及地表设置位移观测点，获取不同推进距离引起的岩层变形值与移动值，进而绘制采空区上覆岩层移动与变形曲线，实验再现了不同推进距离引起地表变形下沉的全过程，掌握了水体浸入作用下采煤后岩层移动及地表下沉的规律，提出了地表下沉最大值点偏向于开切眼。

This paper takes the goafs in Wang Jia-gou which is in south of the Xiao Lang-di reservoir in Xin'an mining area as the prototype and conducts similar simulation experiments indoors. By setting the displacement observation points on the simulation rock strata and surface, we can get the value of the rock strata deformation and movement caused by different advancing distance, thus can draw out the curve of movement and deformation about the strata which is overlying the goafs. The whole process of the surface deformation and subsidence caused by different advancing distance is reappeared in this test and the rules of rock strata movement and surface subsidence under the effects of water immersion is mastered, and therefore the view that the point of maximum subsidence is partial to open-off cut is proposed.
