Abstract: The traditional top coal caving control mainly relies on manual coal caving control, which uses single-round of sequential coal caving. The working face equipped with electro-hydraulic control system mainly adopts the two-round sequential coal caving method combining program control and manual supplementary caving. If the implementation of coal releasing control is not sufficient, the coal recovery rate will be greatly reduced. If a large amount of gangue is mixed in the coal caving process, the coal mining quality will be significantly reduced. In order to solve the above problems, the intelligent coal caving technology in fully mechanized working face is studied. By analyzing the automatic caving process of fully mechanized working face, it is pointed out that in order to realize the intelligent caving process, it is necessary to upgrade shearer, hydraulic support, scraper conveyor and other equipment of the fully mechanized working face on the basis of the automatic caving process. By installing audio and video monitoring system on the fully mechanized caving support, it is able to monitor whether there are large pieces of coal blocking the coal caving opening, affecting the top coal caving. By installing motor current monitoring system at the rear scraper conveyor, it is able to realize automatic control of coal flow. At the same time, the system includes manual intervention functions, such as supplement and parking functions. By installing ash detection system at the end of the belt conveyor, it is able to analyze online whether the ash is increasing. By installing the vibration sensor-based coal and gangue identification device on the fully mechanized caving support, it is able to identify whether there is serious mixed gangue according to the amount of gangue falling based on the vibration sensor data. Combined with the intelligent coal caving process, the intelligent coal caving scheme is customized for the Wangjialing Coal Mine 12309 fully mechanized working face. Based on the automatic sequential coal caving and interval coal caving process, the gangue identification control of vibration signal and the manual coal caving flow control technology, the intelligent coal caving of this working face is obtained. Moreover, the actual application results have verified the effectiveness of the intelligent coal caving technology.
