System evaluation method for block distribution after ore blasting

The invention relates to a system evaluation method for block distribution after ore blasting. The system evaluation method is characterized in that various ore blasting muck piles with uneven sizes formed after mining blasting are selected for shooting; a graduated scale is placed on the surface of the ore blasting muck piles to be shot; the ore blasting muck piles are shot using a method for shooting standard photos in a positive and vertical manner; the total shot area is larger than or equal to 10% of the surface area of the ore blasting muck piles; the photos are processed using the PHOTOSHOP software, a square grid is set on the selected pictures, and the selected pictures are acted by taking the square grid as a standard and are analyzed and evaluated one by one. The system evaluation method for block distribution after ore blasting has the advantages that the block distribution after ore blasting can be easily and quickly analyzed; the blasting quality can be directly and accurately evaluated; the blasting design can be optimized and adjusted according to the analysis result; the system evaluation method has a wide promotion value and can create favorable economic benefits in application.
