Abstract：To ensure the stable operation of the scraper chain transmission system and improve production efficiency,we investigated the tension control technology for scraper chain drive systems in bolter-miners.First,the working principle and mechanical characteristics of the scraper chain transmission system were analyzed to identify key parameters and influencing factors for tension control.Based on this,combining with the actual working conditions of bolter-miners,an adaptive control-based tension control strategy was proposed,thus to achieve precise control of the tension in the scraper chain transmission system by real-time monitoring of tension changes,integrating hydraulic transmission systems and system identification algorithms.Simulation and experimental studies were conducted.The simulation results show that this control strategy enables precise tension control of the scraper chain transmission system,avoiding issues such as chain slack or over-tensioning.Experimental results further verified the reliability and practicality of the control strategy,providing a new solution for tension control in the scraper chain transmission system of bolter-miners.
