In order to solve the problem of energy waste and low transportation efficiency caused by the mismatch between the running speed of shearer and scraper conveyor, and the continuous high-speed running of scraper conveyor, through the study of two-way coal cutting technology, the running phase of shearer and scraper conveyor is analyzed, and a decision model of coordinated speed adjustment between shearer and scraper conveyor is established, which aims at optimizing the consumption of scraper conveyor, the fluctuation of transportation speed and the transportation efficiency. Seagull Optimization Algorithm is used to solve the optimal synergistic speed of each stage under the constraints of speed range and coal load of shearer and scraper conveyor. Finally, the simulation experiment with data from a coal mine working surface shows that the shearer traction speed and scraper conveyor transport speed can be planned by using the decision model of coordinated speed control between shearer and scraper conveyor, which can effectively reduce 28.7% energy consumption of scraper conveyor and increase transport efficiency by 6.8% without affecting production tasks.
