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 ,从而使得以煤矸石为主剂的灌浆材料成为可能 The experimental research results on the physical and mechanical properties (viscosity, stability, setting time, compressive strength and anti-seepage strength) of coal gangue powder grouting material and its stone are introduced. Coal Gangue slurry by adding admixture and change the pulping process to improve its performance, in order to obtain a certain degree of mobility, high diffusion and permeability of the stability of the slurry, so that the main gangue-based Grouting material is possible
