important means to increase output, improve productivity and reduce accident. The coal mining machine is core equipment in the prehensively mechanized coal mining technology, whose automation is the key to realize prehensive mechanized mining. The coal mining machine automatic technology mainly includes the automatic technology of Shearer Hauledpart and the coal mining machine high automatic control technology. In nowadays, the automatic technology of Shearer Hauledpart is rather mature, while drum lifting is not very satisfising, which has bee the the main bottleneck of coal automation. Based on the understanding of the logic relationship among basic structure, working principle and electric control system, this article describes that the coal mining machine cutting memory test bed is posed of mechanical, electrical control and test control system, determines the control logic relationship of electric control system, designs electric control systematic circuit to meet the technical requirements for the memory cutting. According to the test, electric control systematic circuit can control the logic relationship between electrical equipments well.
