Abstract: This paper introduces the construction of full mine safety intelligent video system which is developed by Tiandi Science and Construction Wells Research Institute in Hongqingliang Coal Mine of Haohua Energy Group. This paper expounds the design principles of the system, and expounds the realization of intelligent video recognition algorithms such as the belt stacking coal warning, the over-circulation warning of continuous mining, the empty roof operation warning and the snap shot of personnel and vehicles, as well as the hardware architecture and software architecture, etc., in the intelligent video system, and finally introduces the practical application and effects of the system.
