Embodiment Construction
[0033] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.
[0034] The multi-stage control method of the intelligent fully mechanized mining face coal mining machine described in the present invention analyzes and establishes the coupling relational expression between the gas concentration of the upper corner and the return air channel and the traction speed of the shearer; the upper corner and the return The gas in the Fengshun tank is unified into one evaluation object, named "linkage control gas concentration"; the early warning value of the linkage control gas concentration is divided into five levels from high to low: red, orange, yellow, blue, and green, of which red is the alarm State, green is the safe state, and the other three levels are the early warning state; the traction speed of the shearer is divided into five levels from high to low: 4...
