Abstract: According to an example, with respect to blast reconciliation for mines, pre blast measurement data and post blast measurement data associated with a blasting operation for a mining site may be ascertained from a pre and post blast measurer. A blast reconciliation model may be generated using existing pre blast measurement data and existing post blast measurement data, and used to analyze the ascertained pre blast measurement data and the ascertained post blast measurement data. Based on the analysis of the ascertained pre blast measurement data and the ascertained post blast measurement data, a blast material yield for the mining site may be determined as a result of the blasting operation. An alert indicative of the blast material yield may be generated.

Abstract: The present invention provides a method for setting parameters required for any type of blasting operation using a bar-like charge system by devising equations based on which the maximum blasting efficiency may be achieved within a safe range to prevent flying rock accidents even when the line of least resistance W or filler length P is unknown. When defining a blast hole diameter, i.e., charge diameter as d, a charge hole length as M, a filler length as P, a charge length N=M-P, a fracture radius or interval length as D, and the specific gravity of charge as A, if the charge hole angle with respect to the first free surface G1, is .alpha..ltoreq.90.degree., based on an equation for setting blasting coefficient c: ##EQU1## and by removing the filler length P therefrom, a fracture rock volume V may be determined as: ##EQU2## and a charge amount L may also be determined as: ##EQU3##

Abstract: Rock and other hard materials, such as concrete, are fragmented by a controlled small-charge blasting process. A cartridge containing an explosive charge is inserted at the bottom of a hole drilled in the rock. The explosive charge is configured to provide the desired pressure in the hole bottom, including, if desired, a strong shock spike at the hole bottom to enhance microfracturing. The cartridge is held in place or stemmed by a massive stemming bar of high-strength material such as steel which blocks the flow of gas up the drill hole except for a small leak path between the stemming bar and the drill hole walls. The cartridge-incorporates additional internal volume designed to control the application of pressure in the bottom hole volume by the detonating explosive.

Abstract: A method of smooth wall rock blasting is provided in which an alignment of boreholes for explosive charging is drilled into rock and a single, smaller diameter empty borehole is drilled close and parallel to, and on each side of each charged borehole. Upon detonation of the charged boreholes, the rock is cracked smoothly along the plane coincident with the axes of the holes. The method reduces drilling costs to a minimum and provides improved results over the previous pre-shearing and other known methods.
