Run Of Mine Rock Fragmentation

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.

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.

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.

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 ...

3. Measurement of Size Distribution of Blasted Rock at Limestone Quarry Site of investigation is a limestone quarry producing limestone for cement manufacturing. The mining method at the quarry uses the traditional open pit practice of drilling and blasting a planned rock bench, loading of material with wheel loaders, and hauling to the primary

(PDF) Rock Fragmentation by Blasting – a review

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 to be blasted.

Investigation of rock blast fragmentation based on ...

Bench height is another effective parameter on rock fragmentation. The higher bench height leads to the higher rock column in front of the blasthole. By increasing the height of rock column, its strength decreases. Therefore, the rock column should be better broken in such conditions [12, 43].

Controlling fragmentation - Orica

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.

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.

(PDF) Rock fragmentation control in opencast blasting

fragmentation control in opencast blasting, Journal of Rock Mechanics and Geotechnical Engineering (2016), doi: 10.1016/j.jrmge.2015.10.005. This is a PDF file of an unedited manuscript that has ...

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

Software & Service Overview - Hexagon Mining

from the mine; correlation of PSD to shovel maintenance and enhanced process control decisions; the only place to measure run-of-mine leach ore. Split-Desktop® is the industry approved software standard for manual, off-line coarse rock fragmentation size analysis of muck piles, leach pads and more. Split-NetSM service utilizes our

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 assist with mill production.

Critical Comparison of Julius Kruttschnitt Mineral ...

As part of the Australian Mineral Industries Research Association (AMIRA) P483A Mine to Mill™ project, the Two-Component Model (TCM) and Crush Zone Model (CZM), developed by the Julius Kruttschnitt Mineral Research Centre (JKMRC), were compared and evaluated to measured ROM fragmentation distributions.

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. It was concluded that the "Kuz-Ram" model used to predict the fragment size distribution is incorrectly applied, which resulted in a planned blast design that produces a coarse ...
