Aiming at the system control requirements of MG900/2400-WD coal mining machine and SGZ1000/3×1200 scraper conveyor used in the mine,the cooperative control system of coal mining machine and scraper conveyor is set up.The test results show that:through the application of cooperative speed control technology,it can effectively reduce the ineffective mechanical loss and electric energy loss of the scraper conveyor by about 20％～30％,and the annual maintenance cost of a single piece of equipment can be saved by about 25,000 yuan,with significant technical and economic benefits,and it has achieved the expected purpose of the research.
