In order to improve the intelligent control level and operation efficiency of scraper conveyor and reduce energy consumption,the SGZ 1000/2伊525 scraper conveyor of 9302 fully-mechanized mining face was taken as the research object,and the intelligent speed regulation control system was built and applied in engineering.Through the transformation of SGZ 1000/2伊525 type scraper conveyor drive system,the intelligent drive was realized.The coal cutting amount and blade coal amount can be predicted by combining the current changes of shearer and conveyor,and the load prediction of scraper conveyor can be realized by combining the monitoring data of AI camera,and the running speed can be adjusted intelligently according to the load changes.Field application proved that the intelligent speed regulation of scraper conveyors based on load prediction not only met the needs of efficient coal transportation in 9302 fully-mechanized mining face,but also reduced the energy consumption of scraper conveyors by 36.90%,achieving the expected construction goal.The research results can provide reference for the intelligent control of scraper conveyors in other mines.
