摘要
用Flac3D软件对采煤沉陷控制作用分别进行了数值模拟,得出了开采背斜构造煤层可对地表移动变形起缓解作用,其最大下沉值的量值与背斜翼间角正相关,下沉盆地的影响范围与之负相关;开采向斜构造煤层可对地表移动起加剧作用,其最大下沉值的量值与向斜翼间角负相关,下沉盆地的影响范围与之正相关的结论.
By using Flac^3D software to simulate the control of fold structure on mining subsidence, some results are drawn ： if the other conditions are same, surface movement is alleviated by mining the anticline coal seam, and the positively significant correlation is found out between the maximal subsidence of the movement and angle of limbs of anticline, and the negatively significant correlation is found out between the incidence of subsidence basin and angle of limbs of anticline; on the other hand surface movement is aggravated by mining the syncline coal seam, and the negatively significant correlation is found out between the maximal subsidence of the movement and angle of limbs of syncline, and the positively significant correlation is found out between the incidence of subsidence basin and angle of limbs of syncline.
