| Abstract: | The characteristics of three kinds path of gangue mixing in coal flow from goaf,gob shield and directly into the scraper conveyor were analyzed. The high reliability sensors were designed. The intelligent top coal caving technology was put forward,which was different from manual top coal caving.The route sensor was installed in the jack of tail beam and spile,which realizes the precise control of top coal caving,and improves the practicability and reliability of top coal caving control system. |
