Design of electro-hydraulic control system of withdraw shield support on fully-mechanized face

In view of problem that applying condition of withdraw shield support on fully-mechanized face is bad, and it has danger for underground worker to close to operate the support, an electro-hydraulic control system of withdraw shield support on fully-mechanized face was designed. It gave main technical parameters of the withdraw shield support and its arrangement mode in roadway, introduced composition and configuration of main devices of the electro-hydraulic control system of the withdraw shield support in details. Actual application shows that the system has reasonable design, simple operation and low fault rate, which avoids operation in dangerous area for underground worker.
