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.
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。
The result showed that, the point subsidence of the building was even, and the volume extent and velocity was limited.
分析结果表明，施工各阶段，建筑物主体体沉降速率及幅度均较小，各点沉降基本均匀。
The results showed that the settling velocity of tailings at different concentrations is very low as natural subsidence.
试验结果表明：自然沉降时，该尾矿在不同浓度下的沉降速度均很低；
