Research On Automatic Control System Of Solid Filling Hydraulic Support

With the rapid development of coal mining industry,coal mining is gradually increasing.The solid waste produced by coal mining causes great pollution to the environment,and coal mining subsidence seriously damages the surface ecological environment,agricultural production and human settlements.As a green coal mining technology,solid filling mining technology can effectively solve the problems of waste accumulation and surface subsidence caused by coal mining.Solid filling hydraulic support is the key equipment to realize solid filling mining technology.It integrates coal mining support and filling support to ensure the human safety in working areas and the safety of mechanical equipment.In order to further improve the automatic control level of the solid filling hydraulic support,the research on electric control system of the support was carried out.Firstly,the basic technology of solid-filled coal mining and the solid-filled hydraulic support were studied and analyzed,and the overall scheme of the automatic control system was overview.Secondly,design the hardware architecture of the solid filling hydraulic support control system,then select the PLC,stroke sensor and pressure sensor in use.According to the control requirements of the filling system,design the support controller.The sensors required by the filling system are arranged,multi-source information is collected,and then integrated and comprehensively analyzed to generate a complete filling effect criterion,which realizes the automatic cycle operation of the compacting mechanism and improves the filling quality.Then based on the working process of solid filling hydraulic support and solid filling mining technology,the automatic control system software is designed,which mainly includes single frame with single action,single frame linkage,automatic pressure compensation and alarming.Finally,the monitoring system is designed to increase the human-computer interaction function.According to the filling and mining technology,and produce the related monitoring interface,alarm interface,data report,etc.with Kingview software.The increase of the monitoring interface facilitates the staff to monitor the related equipment more efficiently,perform the simulation debugging to control the movement of the support,and perform engineering application,which has a good control effect and improves the filling efficiency.The research on the electric control system of solid filling hydraulic support can provide some reference for the development of filling mining technology in the direction,and also lay a foundation for the construction of the electric control system,which has a certain practical significance.
