Abstract: The disadvantages of current emulsion supplying methods are discussed, the mathematical model of hydraulic support movement is established and the flow-rate demands of different operations on hydraulic support are analyzed. In order to meet the different flow-rate demands of different operations on hydraulic support, a new emulsion supplying method is proposed, which is based on the identification of the types of the operations on hydraulic support and can provide a matching flow-rate. For proving the reasonability and superiority of this new emulsion supplying methods, AMESim and MATLAB/Simulink are employed to accomplish a joint simulation of the emulsion supplying process.
