Background technique

The fully mechanized caving face is composed of multiple hydraulic supports and other equipment. The coal discharge of the working face is controlled by the swing of the tail beam of the hydraulic support and the opening of the coal opening. In the fully mechanized caving face, it is generally allowed to have 2-3 coal discharges at the same time , therefore, there are 2-3 hydraulic supports that carry out the coal discharge operation at the same time on the working face. Coal discharge, multi-round coal discharge and other coal discharge methods. Coal discharge is generally carried out manually, and the coal discharge process is ended through manual observation. Coal discharge process parameters, coal discharge rounds and coal discharge time parameters are basically unchanged for a relatively period of time. When factors affecting coal discharge (such as coal seam thickness, roof pressure changes, etc.) change, the coal discharge process or coal discharge Parameter adjustment. Due to the many coal discharge process and coal discharge parameters of the hydraulic support, the work of modifying the coal discharge process and time parameters of the working face is more complicated, which is not conducive to adjustment, and the coal discharge process requires manual operation, with a large workload and many uncertainties Factors affecting the coal caving effect and coal caving quality have become the main bottleneck restricting the production efficiency of the top coal caving face.

The support controller is installed on the hydraulic support, the signal converter is installed on the hydraulic support at the end, and the monitoring host is installed at the monitoring center along the channel. Each hydraulic support on the working surface is equipped with a support controller, and the support controllers are connected through a connector to realize data communication between the support controllers. The support controller at the end is connected to the signal converter through a connector to realize The data communication between the support controller and the signal converter, the signal converter is connected with the monitoring host along the trough through the connector to realize the data exchange between the support controller of the working face and the monitoring host along the trough, and the operation is performed on the support controller of the working face. The tail beam and inserting plate of the hydraulic support are controlled by the support controller to realize the coal discharge control of the top coal caving hydraulic support. During the coal discharge process of the hydraulic support, the support controller can send the coal discharge control command to the monitoring system through the signal converter. on the host. When setting up the coal discharge process and time parameters for the first time, before starting coal discharge at the working face, it is necessary to set the memory coal discharge parameters on the monitoring host, and arrange operators on the working face to control coal discharge. The action data of the coal discharge port of the hydraulic support is recorded, stored and analyzed, and a complete set of coal discharge process and time parameters are generated at the end of the coal discharge. In the next coal discharge, the memory coal discharge function can be directly activated on the monitoring host, and the coal discharge process and time parameters saved by it can be controlled one by one according to the stored time sequence to control the coal discharge of the hydraulic support of the working face, thus realizing the coal discharge control of the working face Automatic control of hydraulic support coal discharge.
