Study on automatic and intelligent following control system of hydraulic powered support in fully- mechanized coal mining face

According to the automation following contral program, parameter static features and singleness of the hydraulic powered supports in the fully mechaniz ed coal mining face and to the problems of the dynamic automation following system not be well solved, beads on the varied environment, equipment, technique and dy namic features of the coal mining face and the automation and intelligent following control system was designed from the multi- factor and multi dimensions. The paper i ntroduced the automation following control principle of the powered support, analyzed the several factors affected to the moving speed of the powered support and intro duced the following control and hydraulic supply system, equipment performances, roof and floor conditions, speed of the coal shearer, coal mining technique coupling control strategies, balanced control strategies of the following control link capacity, overall following control and additional powered support added, and other control str ategy. The automation and intelligent following control system was tested in Huangling No. 1 Mine. The results showed that the application of system could improve the intelligent level of automation and intelligent following control system of hydraulic powered support and enhance the suitability of automation following function in order to provide promotion role to the promotion and application of the unmanned coal mining face.
