Application and Research on Intelligent Technology of Collaborative Control of Shearer Bracket
In response to the phenomenon of poor collaborative ability and frequent manual intervention during the automatic cutting of coal body by the shearer and the automatic pulling and moving brackets of the hydraulic support during the stoping period of the working face,taking the 22104 intelligent fully mechanized mining face of Huaning Coking Coal Company as the research object,a hydraulic system based shearer and bracket collaborative control system is constructed.The various parameters of the shearer are introduced into the joint modeling of GA-BP,and the method of combining genetic algorithm(GA)with BP neural network are adopted to optimize the collaborative control of the shearer and bracket,in order to achieve the effect of improving the spacing of the moving brackets and the extended type side protective role.The practice shows that this technological improvement can effectively enhance the control action on the bracket,reduce the deviation of the moving brackets spacing,increase the prediction accuracy by about 10%,greatly improve the production work efficiency of the fully mechanized mining face,and lay a good foundation for the intelligent and automated construction of the mine fully mechanized mining face.
