With the improvement of mineral processing technology,the amount of tailings in storage is increasing year by year,and the particle size of tailings is getting finer and finer.However,such tailings have poor permeability,good water holding performance,long consolidation time and low mechanical strength.Such tailings often have problems such as difficult drainage,slow deposition and poor stability in the process of damfilling.In the complex climate and geographical environment,rainfall infiltration,water evaporation,repeated rise and fall of sat...
