Prediction of Rock Fragmentation Using a Gamma-based . 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.

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.

Rock Fragmentation by Blasting

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.

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.

Rock fragmentation control in opencast blasting ...

Rock fragmentation distribution influences a range of mining and milling processes including load and haul rates, crushing and grinding performance and ore recovery in beneficiation processes (Michaud et al., 1997). In opencast mining, where blasting is employed for excavation, the overall cost effectiveness of the production operations is compatible with optimization of drilling and blasting parameters.

Measurement of Size Distribution of Blasted Rock Using ...

cement manufacturing. Fragmentation is the ultimate measure of efficiency of any production blasting operations. The degree of 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

The effects of short delay times on rock fragmentation in ...

Rock fragmentation is a fundamental goal of bench blasting where the most effective blasts can only be achieved through fragmentation optimization. The meaning of optimized fragmentation is site dependent, as there is no single fragment size that is the most cost effective for all mine sites, loading equipment, and processing facilities.

(PDF) Rock Fragmentation by Blasting – a review - ResearchGate

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. This is of immense importance that we should develop a better understanding of the explosive used and the rock mass …

Controlling fragmentation

Conclusion #1: Fragmentation control is one of the few ways to reduce volatility and increase overall production. This will be discussed further in a later section, giving case examples that consider a mine’s geology, the mining objectives, energy range of bulk explosives, blast design and initiating systems.

Break it Better - Mine Blast Fragmentation - International ...

Better fragmentation through team work at Dos Pobres mine, Safford, AZ, by D. Brandt et al, considered this a copper oxide heap-leach mine where, as mine depth increased, “the proper fragmentation size became harder to achieve due to less weathering and different rock types.

Investigation of rock blast fragmentation based on ...

Investigation of rock blast fragmentation based on specific explosive energy and in-situ block size ... was calibrated by nonlinear fits to 35 bench blasts in different sites from the Sungun copper mine, the Akdaglar quarry, the and Mrica quarry. ... to predict the run of the mine …

Split-TruckCam System - Rock fragmentation size image ...

Some of the benefits of measuring fragmentation of the run of mine material include: Boulder Detection at the Crusher: The system data can be integrated with the operator HMI to provide early indications of large boulders before being dumped into the crusher. Reduce crusher cleaning and rock hammering and overall crusher downtime.

Impact of rom PSD on the crushing and grinding circuit ...

Based on this goal, run-of-mine fragmentation analysis was conducted for four blasting designs resulting in powder factors of 0.44, 0.54, 0.64, and 0.94 kg/t. The powder factor of 0.44 represents a standard blasting design, while the 0.54 and 0.64 kg/t designs are high-energy blasts specifically to …

Productivity improvement of a Ghanaian open-pit gold mine ...

After a statistical analysis of the available data on post-blast fragmentation, it was observed that the desired run of mine (ROM) P80 target of 350 mm is rarely met.

Prediction of rock fragmentation due to blasting in Gol-E ...

Usually, the rock fragmentation is used in the mining industry as an index to estimate the effect of bench blasting. However, a good fragmentation is a concept that it mainly depends on the downstream process characteristics i.e. mucking equipment, processing plant, mining goal etc.
