Abstract

Abstract:

In the condition of mining under thick alluvial, the surface subsidence and deformation have themselves characteristics and regularity. According to geology and mining condition in thick alluvium mine-area, cloud charts of strata vertical movement and surface subsidence curves are obtained in different conditions of alluvial thickness among 100m～350m. the relations are discussed about subsidence maximum subsidence W、subsidence coefficient q、thickness of alluvium, particular laws of the surface movement and deformation are analyzed in the condition of mining under thick alluvial, also the reasons are explained from movement and deformation mechanism of strata and surface. Then the subsidence law is obtained in the specific thick alluvium mine-area.

Key words: thick alluvium, surface subsidence, strata movement, numerical stimulation, subsidence coefficient
