摘　　要：论述了跳汰分选效果取决于分层效果和对二段最佳切割点跟踪的相关性,针对两段跳汰机同时排矸控制的特点和动力煤入洗煤质净煤灰分随机、频繁、大幅度变化条件下对跳汰分选效果的影响,运用"跳汰精煤灰分自动跟踪的闭环控制"新技术,解决了跳汰机二段最佳切割点自动跟踪的难题,实现了高效跳汰分选。Discussed was the relativity of jigging performance being dependent on optimal cut point in second stage; aiming at the special feature of simultaneous discharging refuse in 2 stages of jigging machine and the influence on separation performance by random,frequent and large range variation of clean coal ash of thermal feed coal,by use of closed circuit automatic tracing of the ash content of jig concentrate,the difficult problem of tracing the optimal cut point in second stage being solved and high efficient jigging separation realized.
