摘　　要：介绍了刨煤机组支架电液控制系统结构,重点阐述了支架电液控制关键,包括推移精度控制、快速移架方法及最优梁端距排列控制,给出了相应的解决方案。实践表明,刨煤机组支架电液控制系统能够精准控制支架自动推移步距,移架时间约为8s,且工作面未出现掉顶或片帮现象。Structure of electro-hydraulic control system of support used for coal plough unit was introduced and keys of electro-hydraulic control of support as well as solutions were focused on including precision of support pushing, support quick-moving and optimal arrangement of tip-to-face distance. Application shows that the electro-hydraulic control system of support used for coal plough unit can precisely control automatic pushing-step of support with moving-forward time of 8 s, and there is no top off or rib spalling.
