Blastability Classification of Fractured Rock Mass Based on Weighted Clustering Analysis

open access: yesChemical Engineering Transactions, 2017
This paper classifies the blastability of fractured rock mass based on the solid coefficient, rock impedance, unit explosive consumption and mean fracture spacing. Specifically, an evaluation model was established according to the principle of clustering

Powder factor prediction in blasting operation using rock geo-mechanical properties and geometric parameters [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering, 2022
Prediction of powder factor is a major activity while preparing drilling and blasting operation, as the total production cost depends on it. It is a major input parameter in blast design as it influences the efficiency of subsequent operations in mining.

Development of new comprehensive relations to assess rock fragmentation by blasting for different open pit mines using GEP algorithm and MLR procedure [PDF]

open access: yesInternational Journal of Mining and Geo-Engineering, 2022
The fragment size of blasted rocks considerably affects the mining costs and production efficiency. The larger amount of blasthole diameter (ϕh) indicates the larger blasting pattern parameters, such as spacing (S), burden (B), stemming (St), charge ...
