煤矸石粉灌浆材料的试验研究

Experiment Research on the Filling Slurry Produced from Coal Refuse Powder

介绍了煤矸石粉灌浆材料及其结石的物理力学特性 (粘度、稳定性、凝结时间、抗压和抗渗强度等 )的实验研究成果。通过对煤矸石粉浆液掺入外加剂和改变制浆工艺来改善其相关性能 ,以获得具有一定流动度、较高的扩散性和渗透能力的稳定性浆液 。

Introduced were the experiment research results on preparation of filling slurry from coal refuse powder and the physical and mechanical characteristics of slurry and solidified mass thereafter (viscosity, stability, solidifying time, compression strength, anti permeability). By addition of some ingredient and process conversion, its related propertied had been improved and a stable filling slurry of higher disperse ability and permeability produced, which enabled the production of filling slurry from coal refuse powder.
