The result shows that when the emulsifying agent layer not perfectly covering the primary particles' surface or the primary particles' surface being covered with overmuch powder grain, it will lead to the higher plastisol viscosity.

结果表明初级粒子表面的乳化剂层包覆不严或表层粉粒太多，均会导致增塑糊粘度偏高；次级粒子聚结松散，结构脆弱，有较低的糊粘度和触变性；次级粒子聚结紧密，有熔结现象，增塑糊粘度偏高。

The time space regularity of overlying strata movement and damage induced by coal mining was studied using the dynamic mechanics model. The developing regularty of faults and bed separation as well as surface subsidence caused by mining was analyzed based on the geological and mining conditions of working face 5306 in Xinglongzhuang Coal Mine. The data explaination using the model is more reasonable than that using other models. So it can be used in practical mining activities.

采用采动岩体动态力学模型，对采动引起的覆岩移动破坏的时空规律进行了研究，结合兴隆庄矿5306工作面的地质、开采条件，对采动引起的断裂带发育发展规律，岩体内部离层发生发展规律、地表下沉规律等问题进行了分析，并对观测结果作出了较以前的各种理论模型更为符合实际的解释，该模型可在实际工作中得到很好地应用。
