矸石分选是煤矿生产的重要环节 ,即在煤块中将矸石挑选出来 .目前我国大块矸石的分选大多采用手选 ,工人劳动强度大 ,生产效率低 ,工作环境恶劣 ,严重影响着工人的身心健康 .通过采用图像处理和模式识别技术对煤块和矸石进行识别 ,再结合计算机技术和机械自动化技术 ,从而达到了煤矸自动分选的目的 . Gangue sorting is an important part of coal production, that is, gangue will be picked out in the coal block.Most large gangue sorting hand-selected, the workers labor-intensive, low productivity, poor working conditions, seriously affecting the workers Physical and mental health.Through the use of image processing and pattern recognition technology to identify coal and gangue, combined with computer technology and mechanical automation technology, so as to achieve the purpose of automatic sorting coal gangue.
