Description

Technical Field

[0001] This utility model relates to the field of coal mining automation, and in particular to an automatic control system for a coal mining face. Background Technology

[0002] The development of automated control technology for coal mining faces is an evolving process, transitioning from traditional to modern mining methods. In the initial stages, automated control technology focused primarily on the simple control of mining machinery, such as controlling the cutting speed and depth of the coal mining machine mechanically or hydraulically. With technological advancements, automated control technology for coal mining faces entered a developmental stage, characterized by the introduction of sensors and microprocessors, enabling remote control and real-time monitoring of the coal mining machine. However, the level of automation in current coal mining technologies remains low, primarily due to the inability to integrate electromechanical equipment and safety control systems, still heavily reliant on manual intervention. Currently, there is a lack of corresponding solutions to these problems. Utility Model Content
