多煤层开采覆岩移动及地表变形规律的相似模拟实验研究
Similar simulation of overlying rock movement and surface deformation behavior with multi-coal seam mining
摘要
Abstract
Taking geological conditions of Kangjiagou coal mine under Lishi-Jundu freeway as a prototype, similar material simulation was carried out for examining the behavior of overlying rock movement and surface deformation with multi-coal seam mining. The results show that under the condition of multi-coal seam mining, with the increase of total thickness of coal seam, the overlying rock subsidence of three zones of gob and surface subsidence, surface lean deformation, surface level movement, surface curvature deformation all show an increasing tendency, the overlying rock of gob is more broken, the surface deformation is more intense. The results provide the basis for the treatment design of gob with multi-coal seam under freeway.关键词
