Design of electromechanical and hydraulic integration virtual simulation platform for shearer mining operatio

In view of problems that current virtual simulation of shearer mining operation are mostly based on preset trajectories, seldom consider impact of coal seam loading and can not show dynamic process of shearer operation, three-dimensional simulation of shearer mining operation, electrical and hydraulic system simulation, and specific working conditions are combined to design electromechanical and hydraulic integration virtual simulation platform for shearer mining operation using LabVIEW and Simulink interactive program development technology. Under condition of sudden change of coal seam load, the drum speed and traction speed are automatically adjusted to reduce the drum load through the control of electric speed control system and hydraulic height adjusting system. The test results show that the platform can accurately and visually display dynamic process of shearer operation and control process under condition of sudden change of coal seam load. In the shearer operation training, the platform can help shearer operator to master shearer control strategy under condition of sudden change of coal seam load to avoid actual operation risk.
