Determining minimum burdens for quarry blasting

Determining minimum burdens for quarry blasting

The use of Power Factor in blast design Using the rock type the designer can select the Powder Factor range suitable for the quarry. The face profiles will identify reduced burdens. Table below relates the explosives loading rate and the reduced burden to the expected ‘In-Hole’ Powder Factor (for a one metre section of 110mm diameter borehole)

A Combination of Expert-Based System and Advanced

Nov 13, 2020 This study combined a fuzzy Delphi method (FDM) and two advanced decision-tree algorithms to predict air-overpressure (AOp) caused by mine blasting. The FDM was used for input selection. Thus, the panel of experts selected four inputs, including powder factor, max charge per delay, stemming length, and distance from the blast face. Once the input selection was completed, two
