Abstract: Knothe time function is used to forecast surface subsidence, but the Knothe time function cannot simulate the subsidence rate and acceleration. According to the limitation of Knothe time function, the improved time function of surface subsidence, time function of surface subsidence based on Logistic growth model, is presented. Logistic time function can describe the whole process of surface subsidence and simulate the subsidence rate and acceleration according to the measured data of mine. The results indicate that the method is effective and applicable.

Key words: subsidence, time function, Logistic growth model, prediction
