Abstract

Analysis on the current research status, this article studies on the dynamic subsidence principles of overburden rock strata during coal mining based on similar material simulation test. Close ranged industrial photogram metric system was introduced to collect data. After coordinate transformation, matching and model amendment, dynamic subsidence curves which can be used to analyze the continuity characteristics of overburden subsidence, changes of boundary angle and displacement angle, volume transferring law from rock to surface, etc. were got. The result is useful in further study of the dynamic rule of overburden strata and enriches mining subsidence principles.
