Intelligence Mining with Electro-Hydraulic Control Technology
The underlying way to reduce accidents is reducing the number of workers on the coal face. Automatic mining can realize this object. The key for unmanned automatic mining is the application of electro-hydraulic control technology used on workface support. The electro-hydraulic control system applied in Wannian colliery has following function: Automatic moving , lowering and rising of support, monitoring and display of roof pressure; Shearer locating, controlling of cutting height and shearer speed, remote operation and procedure running; Automatic tension of conveyor chain, conveyor operation with constant power and monitoring and fault diagnosis of conveyor speed reducer.
