mines and can provide safe,environmentally friendly,and efficient technical support for deep underground mining.As the theoretical basis of paste backfill,the rheological concepts,characteristics,and models of paste had been systematically reviewed,and the rheological measurement methods were analyzed herein.Rheological measurement enables the quantitative characterization of the rheological behavior of paste,and on this basis,a series of studies,such as the rheological constitutive equations of paste,evaluation of the influence of both internal and external factors on paste rheology,and quality control of CPB,was conducted.Generally,the rheology of paste is influenced by certain constituents,including solids concentration,particle size distribution,density,and cement hydration,and various external conditions,such as shear stress and temperature.The rheological properties of paste differ significantly,and currently,a unified method is not yet available for the rheological measurement of paste.Hence,comprehensive knowledge of rheological measurement is essential to achieve a better combination of rheology and CPB engineering,particularly in consideration of the specific physical and chemical properties of tailings and the common practice in the mining field.Therefore,the principles and applications of commonly used approaches,including the vane rheometer,slump cone,L-shaped tube,inclined pipe,and loop facility,were summarized,with emphasis 收稿日期:2019-10-29 基金项目:中国博士后科学基金资助项目(2020T130272.2019M663576):国家自然科学基金资助项目(52074137.51834001):金属矿山高效
