Abstract

Explosives are commonly used in the mining, quarrying, and excavation industries for breaking rocks and ore. Generally, a hole, referred to as a “blasthole,” is drilled in a surface, such as the ground and explosives are placed within the blasthole. Typically, multiple blastholes are used for breaking large amounts of rocks and ore, which introduces complexities for planning for a blast. A method for generating a blast plan to blast at least a portion of a blast site is disclosed. The method comprising receiving blast data comprising geometric and geological properties of a bench of the blast site to be blasted and a diameter and explosive properties of an available explosive product, wherein the geometric properties of the bench include a face height of the bench; determining a pattern footage representing an area capable of being properly fragmented by the available explosive product in a blasthole located in the bench, wherein determining the pattern footage comprises determining a relationship between the face height, the specific energy of the available explosive product, and the geological properties of the bench; determining a burden and a spacing from the pattern footage; and generating a blast plan using the burden and the spacing to blast at least a portion of the blast site.
