3d block modelling of a resource boundary in a post-blast muckpile to optimize destination delineation

A method for 3-D block modelling of a resource boundary in a post-blast muckpile to optimize grade control polygons for ore control, comprising:

• inputting an in-situ pre-blast block model;
• populating a movement vector field and inputting said vector field data;
• inputting post-blast topographic data;
• inputting blast data selected from the group consisting of blast design, explosive loading data, and hole detonation firing time;
• combining said pre-blast block model, said movement vector field data, said blast data, and said post-blast topographic data to generate a three-dimensional vector field;
• moving a plurality of pre-blast block model centroids to populate a three-dimensional post-blast model;
• and
• optimizing said populated three-dimensional post-blast model to determine a plurality of sets of optimal dig boundaries based upon said grade control polygons.

A method of optimizing grade control polygons in a post-blast muckpile, comprising,

• a memory module coupled to a computer processor configured to store in-situ pre-blast block model information;
• a processor module coupled to a computer configured to generate a 3-D vector field;
• determining in-situ pre-blast parameters and inputting said parameters into said memory module;
• gathering post-blast topographic survey data and inputting said data into said memory module;
• generating movement vector field data with said processor module;
• and
• optimizing said vector field data to determine optimal dig boundaries with said grade control polygons.

In an electronic system for storing and manipulating information, a computer implemented method of representing a three-dimensional post-blast block model of resource boundaries on a screen display, the method comprising:

• displaying on said screen display a three-dimensional vector field comprising optimal dig boundaries in said post-blast block model;
• said dig boundaries comprising stored data, at least some of said data comprising user-supplied information and formulas operative on said user-supplied information;
• said user supplied information comprising a plurality of centroids arranged horizontally according to a measured horizontal movement and an assumed horizontal movement between measured points;
• said user-supplied information further comprising pre-blast block model data, movement data, blast design information and post-blast topographic data;
• and
• said pre-blast block model data comprising design blast hole layouts, loading plans and hole detonation firing times.
