Rock Fragmentation by Blasting - Orica
The fragmentation of rock is fundamental to mining. It is the first preparatory stage in the extraction process – making rock small enough and loose enough to be efficiently excavated. But this simple statement underestimates how important this activity is for the whole mining operation. By optimising rock fragmentation by blasting, you can achieve significant improvements in waste productivity, mill throughput, fragmentation profile and wall stability.
Development of 3D rock fragmentation measurement system ...
Run-of-mine fragmentation is an important aspect of mine productivity optimisation, as it affects all mine-to-mill processes. In this study, a 3D rock fragmentation measurement (3DFM) system is proposed that can surmount the limitations of conventional 2D photo-based rock fragmentation measurement methods.
Prediction of Rock Fragmentation Using a Gamma-based Blast ...
A blast fragmentation model is developed based on the gamma function to describe the run-of-mine fragmentation distribution. The model presented is aimed to benefit from simplicity in application and also to be efficient in description of the fine to coarse part of the blast rock fragments. In fact, the gamma based model (KC-KUM), gives a...

Image analysis as a technique for fragmentation measurement of rock piles has been the subject of research since the 1980’s and to date, run of mine (ROM) fragmentation optimisation studies have primarily relied on particle size measurement using photographic based 2D imaging systems. Cited by: 14
A new framework for evaluation of rock fragmentation in ...
Apr 01, 2019 · A model incorporating Rock Engineering Systems (RES) method was proposed by Faramarzi et al. (2013) to predict rock fragmentation in Sungun copper mine in Iran incorporating 16 effective parameters. Their model was compared by regression analysis and Kuz-Ram model. They concluded that the RES approach is more reliable than other two methods.

STORRE: Prediction of Rock Fragmentation in Open Pit Mines ...
Fragmentation of the rock after blasting is an important determinant of the cost associated with these two components of mine development. In this paper, fragmentation of the rock after blasting is estimated analytically by the use of neural network method.
Measurement of Size Distribution of Blasted Rock Using ...
fragmentation plays an important role in order to control and minimize the loading, hauling, and crushing costs. The size distribution analysis of the rock fragmentation by sieving is a direct and accurate method but it is very time consuming and costly. Fragmentation analysis by digital image processing is a low cost and quick method.
Prediction of Rock Fragmentation in Open Pit Mines
Three types of rock such as oxide, top magnetite and bottom magnetite are extracted in Gol-e-Gohar Iron Ore Mine. During the rock dimensions study, it is attempted to select 50 patterns until the fragmentation of all three rock types are being evaluated. Also waste and soil fragmented distribution are measured during shovel loading.

Rock Fragmentation by Blasting – a review The rock fragmentation process in mining currently being practiced in India needs re-examination to improve the productivity of the mine.
Blast optimization - liming
Optimizing blast fragmentation to improve comminution efficiency. The Run-of-Mine (ROM) size distribution has a large impact on the performance of downstream crushing and grinding processes. The in-situ ore properties, drill blast pattern, and properties of the explosive govern the size distribution of rocks produced from a blast and the energy efficiency of the blast.
