摘　　要：分析实际岩移观测资料及Knothe时间函数,提出完善、补充Knothe时间函数理论的覆岩岩性参数概念,探讨了覆岩岩性参数和时间影响参数的确定方法及二者之间的关系。这对地表及岩层的动态移动预测和三下开采设计具有理论和实用价值。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.
