Feb 01, 2000018332Blasting as a means of rock removal is relatively expensive. A balance is required between the financial and environmental costs associated with blasting and the degree of fragmentation needed for mechanical extraction andor crushing operations to be viable.
Unitronic blasting using accelerated initiation timing has shown a notable improvement in the primary crushing process with throughput increased 18.3 percent, from 191 tph to 234 tph. This result was further calculated to show accelerated electronic timing delivered an additional 28,372 tonnes of primary crusher throughput with no additional ...

resulting from blasting using the blasting data measured at theAnguranmineinIran.Inaddition,anewalgorithmbased on the artiﬁcial bee colony ABC algorithm was utilized to optimize the blasting pattern in this mine. Previous investigation Numerous researchers have focused on the prediction of backbreak and fragmentation through artiﬁcial ...
Jun 10, 2015018332This can be difficult and here at Academy Blasting we spend a good amount of time taking student through many variations of connecting powder columns for proper initiations. Stemming is also extremely important in the top of a blast hole. Using proper stemming is one of the best ways to increase your fragmentation and sizing ranges.

The economic analysis of the use of explosives is an important part of blasting operations in mining and construction. Explosives are energy, and the efficient use of this energy is a major factor in keeping rock blasting costs under control. Highenergy explosives enhance fragmentation, which ultimately produces a positive effect on production ...

OPTIMISATION. BME’s exclusive M2M service offering delivers the full range of benefits across the mining value chain. Blast designs can be optimised to achieve required fragmentation, blast movement, and muckpile shape, delivering improved loading, crushing, and milling rates.
Aug 12, 2016018332TECHNICAL REPORT Control and Prediction of Blast Fragmentation and its Impact on Comminution JAMES DUNFORD 630024723 Abstract Blasting is a fundamental part of the comminution process in mining. Controlling and forecasting the fragmentation from a blast through design and modelling will help in the optimisation of the comminution circuitfor any ...
resulting in less crushing in the secondary and tertiary stages, may mean less improvement through crushing. Therefore, the mineral quality andor changes in physical properties of the product may be affected. Figure 52. Drilling Figure 53. Blast or Shot
Additional blast fragmentation improvement and its impact on blast damage and wall control was investigated as part of this contract. Following the PIO methodology described above, three trial blasts using higher energy intensity were conducted for the harder M4M4A ore and campaigned through the plant to assess the comminution circuit performance.
