摘　　要：用分形对3604S4工作面和回采巷道顶板进行了研究,得到了该工作面下沉速度的几种分维值。通过对分维的分析,说明分维能充分反映顶板运动,为科学的预报顶板来压提供了一种新方法。Study was conducted on the roof of No. 3604S4 coal face and the actual mining roadway with fractals, and a few kinds of functional values of subsidence velocity of this face were obtained. The analysis on the functional values showed that they can fully reflect roof movement and provide a new method for the scientific forecast of roof weighing.
