Study of Dynamic Coordinates Time Function in Mine Subsidence

Abstract:

According to hot research of subsidence time function at home and abroad in recent years that there are commonness of less parameters and difficult to extended reflecting surface subsidence characteristics in the dynamic process, the surface subsidence dynamic coordinates time function were proposed based on the probability integration principle, established the calculation methods of surface dynamic process, anal sized the applicability and limitations of the dynamic time function and verified some examples. The results show that the function is more accurate than the Knothe time function in analyzing the actual regularity of surface subsidence caused by underground mining, reflecting the dynamic characteristics of surface movement in real time, interoperating mining phenomenon, it is more accurate to predict dynamic ground displacement and deformation which has a certain significance value in mining design and subsidence disaster management.
