·Rock fragmentation due to blasting depends upon many parameters The properties of the explosive are one of them In limestone quarries ammonium nitrate fuel oil ANFO or site mixed emulsion SME are generally used for rock fragmentation Both these explosives cause substantial changes in the breakage mechanism of rockmass thereby
MORE The pressure distributions of explosion fields in air resulted from 2 4 kg 15 kgand 42 kg of TNT and rock emulsion explosives were respectively measured and their pressurescaled distance relations consistent with the experiment results were also The
·The computation from the application package revealed that 611 blast holes require kg of high explosives 166 cartons of explosives and kg of low explosives 806 bags of explosives
·The explosive used in the test was rock emulsion explosive manufactured by Nanjing Changshan Chemical Co Ltd and the shape of the explosive was cylindrical The TNT equivalence coefficient of the rock emulsion explosive was determined to be by Fan et al [24] The explosive was hung m right above the mid span of the tested beam
·The charge weight of the rock emulsion explosive was converted to that of TNT by the equivalent coefficient obtained in the literature [20] In addition unlike spherical explosives the influence of the D/L ratio of the explosive cylinder [29] plays a key role in the overpressure and impulse Therefore the same D/L ratio was taken into
·Emulsion explosives EE are one of a typical industrial explosive that is widely used in engineering and mining applications due to its high detonation performance and ideal safety characteristics However since an EE is a multicomponent mixture with an oil in water structure the presence of some substances or impurities can reduce the safety of the EE and
·All explosives used were from the same batch of No 2 rock emulsion explosives The linear charge density ranged from 1 to g/cm 3 the charge diameter was 13 mm and the explosive
This paper examines the practical and economic benefits of using bulk emulsion explosives in underground development mining; compared to ANFO ANFO derivatives and packaged explosives The key economic benefit of bulk emulsion is the replacement of relatively high cost packaged explosives with a bulk product Key practical benefits include water resistance
In rock blasting for mining production stress waves play a major role in rock fracturing along with explosive gases Better energy distribution improves fragmentation and safety lowers production costs increases productivity and controls ore losses and dilution Blast outcomes vary significantly depending on the choice of the explosive and the properties of the rock mass
The use of explosives in the mining industry dates back to the seventeenth century when Caspar Weindel employed black powder known by the Chinese since the second century and used for war purposes since the twelfth century to break a rock in an underground mine in Schemnitz Banská Štiavnica in current Slovakia

Dyno Nobel is at the forefront of explosives technology delivering groundbreaking solutions We acknowledge the Traditional Owners of the lands upon which we operate and recognise their continuing connection to land waters and culture We
·Secondary emulsion explosives serve as the explosive material and non electric millisecond detonators are employed to simultaneously ignite the drilled holes Post blasting the surface cracks in the blasted hole sever the roof rock along the designated direction of
·To address the sensitivity of emulsion explosives to various parameters including pressure a study of a particular ammonium nitrate AN based emulsion explosive has been undertaken using the ARC
·The study shows that SC CO breaks the rock in an elliptical volume shape the explosives are round the range of SC CO fracturing breaks the rock is smaller than the range of explosives breaks the rock and the unit consumption of CO is 6 10 times of the unit
·This review explores the stability of emulsion explosive through summarizing its instability reason stability mechanism affecting factors improvement ways and evaluation methods The emulsion explosive can be recognized as highly concentrated emulsion due to the volume fraction of dispersed phase exceed 74% The polydispersity deformation of
·W Single blast equivalent of TNT explosive mass Kg Under the given atmospheric pressure conditions the TNT equivalent coefficient of the rock emulsion explosive is Fan et al 2011 then the TNT mass equivalent to emulsion explosive is W k m u ee 2 116
·This emulsion explosive had a relatively limited lifetime and an improved and stable emulsion explosive called aquaram was later invented by Bluhm in 1969 Bluhm emulsified a hot water solution of ammonium nitrate and sodium nitrate in mineral oil containing an emulsifier and then sensitized the emulsion by either aerating in a high shear mixer
