| 中文摘要: |
| 全尾砂膏体充填系统为复杂系统,为制备合格的膏体,对全尾砂胶结料的浓度及灰砂比控制要求极其严格,为此,设计合理的控制系统是制备合格的全尾砂膏体的前提条件.不同的矿山,充填工艺不同,充填材料组成及性能差别也很大,应进行控制系统专题研究与设计.本文通过对黑龙江某钼矿全尾砂膏体充填系统工艺特点及全尾砂膏体性能参数的分析,设计了充填控制系统的目标和结构,即实现对灰砂比和充填料浆浓度的控制,以及采用DCS结构.然后进一步对控制系统方案进行了设计,包括采用双闭环比值控制方案,模糊PID控制算法等,以便为进一步设计工作提供参考. |

| Unclassified-tailings paste filling system is a complex system.It's extremely strict with the requirements of concentration and cement-to-tailings ratio to produce qualified paste,therefore,it is the prerequisite to design an economical and efficacy control system to produce qualified paste.It is necessary to design the control system specially,because the backfilling material composition and the performance difference is big in different mining with diverse backfilling technology.This paper analyzes the process characteristics and the performance parameters of unclassified-tailings paste for backfill mining system in a molybdenum mine of Hei Longjiang at first,then designs the target and the structure of the system,that is,controlling the cement-to-tailings ratio and concentration efficiently,and adopting the DCS structure.Finally we design the scheme of the control system including the dual closed-loop ratio control scheme,the fuzzy PID control algorithm and so on,which is convenient for further design work. |
