摘要
针对钾石盐矿实现无发废开采的尾矿处理问题进行了研究,通过实验室镁水泥与钾石盐尾矿胶结强度试验,给出了满足嗣后充填和上向分层充填采矿法充填体强度的镁水泥添加量,并通过SEM研究镁水泥在钾石盐尾矿充填中的胶凝机理。
In this paper,a study was done about potash tailings disposal problems to realize mining paste-free in laboratory.The amount of oxy-chloride magnesium cement which suit the strength of subsequent-backfill and up-backfill mine method was given by the strength tests of oxy-chloride magnesium cement and potassium tailings bonded.In the same time,the gel mechanism of Oxy-Chloride Magnesium Cement and potassium tailings was studied by SEM.
