In order to study the stability effect of PVA fiber and cement on molybdenum tailings,unconfined compressive tests were conducted on PVA fiber reinforced cement stabilized molybdenum tailings.Through single admixture experiment and orthogonal experiment,the influence trend and degree of fiber content,fiber length and cement content on the unconfined compressive strength of fiber reinforced cement stabilized molybdenum tailings were studied.The results showed that fiber and cement had obvious stability effect on molybdenum tailings.With the increase of fiber content,the unconfined compressive strength and residual strength of fiber reinforced cement stabilized molybdenum tailings both showed a trend of increases at first and decreases followed.With the increase of cement content,the unconfined compressive strength of fiber reinforced cement stabilized molybdenum tailings showed a linear increase trend,and the residual strength was also constantly improved.The influence of fiber length on unconfined compressive strength of molybdenum tailings was not obvious.The influences of three factors on the unconfined compressive strength of molybdenum tailings were in descending order of cement content,fiber content,and fiber length.The optimum mix ratio is cement content of 8％,fiber content of 0.2％,fiber length of 12mm.The research results provide reference for the reuse of molybdenum tailings.
