我们所要研究的对象是在库兹巴斯煤田地质条件复杂,且岩层受到破坏情况下,运用不同开采方法开采急倾斜煤层群时的地表岩层移动过程。就库兹巴斯煤田地质条件复杂而又受到破坏的岩层,其移动过程的特性如下: 1、在埋藏小于400m深,用冒落法开采急倾斜煤层时,塌坑出露地表。 2、在冲积层下方,向斜褶皱轴向表面露头上方,以裂隙和台阶形式形成集中变形。 3、移动盆地的形状及其变形分布的特点确定于被采动岩体内大断层和向斜轴向面的位置。 4、在确定由于采动引起总的移动和
The object we want to study is the movement process of surface strata when mining the steep coal seams with different mining methods when the geological conditions of the Kuzbass coalfield are complex and the rock layers are damaged. The characteristics of the moving process of rock formations with complicated and damaged geological conditions in Kuzbass coalfield are as follows: 1. When the steep coal seam is buried with a depth of less than 400m, the collapse pit exposes the ground surface. 2, below the alluvial layer, oblique folds above the axial surface of the outcrops, the formation of cracks and steps in the form of concentrated deformation. 3, the shape of the moving basin and its deformation distribution characteristics identified in the faulted mass of rock and the axis of the synclinal position. 4, in determining the total movement due to mining and movement
