In order to promote the development and application of intelligent fully-mechanized caving mining technology and comprehensively improve the technical level of intelligent coal mining,in response to industry common problems such as automatic coal caving and automatic coordinated operation of working face equipment,the development is based on the practice of top coal mining technology. The intelligent fully-mechanized caving control system with the goal of“equipment automation,automatic data acquisition and unattended operation” was proposed. The technical path and overall architecture of intelligent control system for fully mechanized caving mining were proposed. Complete set of reliability equipment such as MG750/1860-WD shearer,ZF12000/22/42D hydraulic support and SGZ1000/2400 scraper conveyor,BRW630/37.5 emulsion pump station and DSJ140/260/3×500 belt conveyer were equipped. Key technologies and control systems such as hydraulic support memory coal caving,shearer memory cutting,triangular coal cutting technology,coordinated operation of the conveyor system andautomatic control of pump station were developed and the“ground total monitoring and dispatching-roadway area control-subsystem”three -levels control system was built. Industrial tests were carried out on the No.7302 working face of Baodian Coal Mine,with the average thickness of coal seam of 9.04 m. The technical challenges of automatic cutting at the end of the working face and the optimization of intelligent time-sequence coal caving parameters were solved.  Methods such as optimization of mining technology and establishment of operating standards for important posts were used to ensure normalized and intelligent operation. The results show that the intelligent fully-mechanized caving system has realized the automatic and coordinated operation of“mining-caving -transporting”. The sequential automatic caving rate has reached more than 70%,the memory cutting operation rate has reached more than 85%,and the number of workers at the working face has been reduced by nearly 60%. Mining energy efficiency has been greatly improved,reaching an annual output of 10 million tons,realizing an intelligent fully-mechanized caving production mode of “automatic control as the mainstay and manual intervention as the supplement”.
