The invention provides an intelligent analysis and early-warning method for monitoring illegal explosive filling during blasting of an open-pit mine. The intelligent analysis and early-warning methodcomprises the steps that 1, during blasting operation of an open-pit mine, a blast hole is drilled by a drillman, and the blast hole is filled with the explosive by a blaster; 2, a paying off sensor of an igniting primer is mounted, and the paying off speed is monitored; 3, a leg wire of the igniting primer is coated with double colors of the red color and the white color in sections; 4, when theexplosive is put, only the blaster and a supervisor are allowed to be at a blasting site, personnel not related to blasting operation is strictly prohibited to enter the site, and when video recognizes that irrelevant personnel is at the site, automatic alarming is conducted; 5, when the explosive is put, only the blaster and a supervisor are allowed to be at a blasting site, personnel not relatedto blasting operation is strictly prohibited to enter the site, and when video recognizes that irrelevant personnel is at the site, automatic alarming is conducted; and 6, early-warning information is transmitted to a production monitoring room through the 4G wireless network. According to the intelligent analysis and early-warning method for monitoring illegal explosive filling in open-pit mineblasting, all unnecessary casualties and property losses caused by illegal explosive filling during the blasting process can be greatly reduced.
