|
|
Abstract The data of practical observation of rock movement and the Knothe time function are analyzed，the concept of cover rock characteristics is proposed as a supplement for the Knothe time function，and the determination method of the rock characteristic parameters and the time influencing parameters as well as the relations between them are discussed. The result has theoretical and practical value for predicting dynamic movement of surface and rock layer and mining designing.
