Access blasting knowledge faster- through our online information base
In the mining industry, in-depth knowledge is crucial for driving and sustaining change. The global DynoConsult group possess that knowledge and deliver it, often teaming up with industry to conduct technical studies and offer the industry insights to significantly reduce costs and optimise processes. Below is a library of papers we’ve developed:
The Enterprise Solution to Integrating Blasting into the Mining Process
This paper elaborates on the use of statistics to integrate blasting into the mining process to increase productivity, and indicates methods to maximize total enterprise returns starting from basic explosive physical processes to final profitability analysis.

A Statistical Approach to Integrating Blasting into the Mining Process
Complete modeling and simulation of the vibration and air blast results of blasting is now accomplished statistically from blasting database information. nevertheless, because of the unique nature of the blasting process and the equally unique mining processes, blasting and mining processes have not been fully integrated as with other physical systems.

A Blaster's Tool to Measure Fragmentation
The use of digital fragmentation photo analysis is growing in response to the needs of the mining industry to further integrate blasting into the mining process. While the commercial digital imaging systems are highly developed and very accurate, blasters cannot always afford the cost, cannot wait for the analysis nor do they always have the tools or time available to complete a full analysis using these commercial digital imaging systems or their services.

Blast Fragmentation for Maximising the Sag Mill Throughput at Porgera Gold Mine
The Porgera joint venture and Dyno Nobel have commissioned a joint project to optimise the drill and blast opertions to increase the overall profitability of the mine. One of the aims is to increase the throughput of semi autogenous (sag) mill by optimising the blast fragmentation.

Modelling the Impact of Rockmass and Blast Design Variation on Blast Fragmentation
Introduction of a stochastic modelling approach to blast fragmentation models, taking into account the effect rock mass properties, explosive properties and blast design variables have on the resulting fragmentation size distribution.

On the Use of Mechanistic Blast-Outcome Measurement and Modelling for Optimisation of Explosive Selection in Underground Mining
This paper describes the use of a range of dynamic blast measurement and outcome modelling techniques to explore the relationship between rock properties, explosive properties and mining process efficienciees; and discusses the understanding gained concerning the limitations and capabilities of a selection of analysis and modelling approaches.

Bulk Loading of Emulsion Explosives in Shaft Sinking
This paper discusses ways and means to improve productivity in the shaft sinking process, by looking at such factors as drilling, hole diameter, drill patterns, explosive type & load, initiation techniques, cut design, wall control, fragmentation and heated magazines.

Optimum Blasting?
Optimum Blasting? Is it minimum cost per broken rock or maximum value per broken rock?
More
Tamping Practices in Development Blasting
The influence of cartridge length and tamping practices on the efficiency of packaged emulsion explosives in development blasting.
More
Optimising Development Blasting
Discusses the use of blast monitoring/modelling technology for the optimisation of development blasting.
More
Benefits of Blend Programs in Surface Coal
Discusses the benefits of a 9mth and 4mth blast optimisation program for surface coal mines designed to demonstrate how using a 40/60 blend to replace ANFO could reduce overall mining cost.
More
Estimating ROM Size Distribution
A fragmentation model to estimate ROM size distribution in soft rock types.

DynoMiner™ APS Underground Explosive Loading System
This paper introduces a new, safer bulk emulsion loading system for underground mining operations. The features and benefits of the equipment, along with the use of Dyno Nobel patented gassed emulsion technology, is summarized in the application of a stope blast with very difficult and complex ground conditions.

Developments with Electronic Detonators
The mining and explosives industry is rapidly adopting technology in all forms in order to improve performance. One such technology that is being developed to improve blasting efficiency and mining economics is the electronic detonator.
More
Explosives Malfunction in Decked Blasts
The time domain during which an explosive detonates and causes rock to fragment and displace is on the order of tens of milliseconds. Because of this, the dynamic processes that occur during this time frame often become a source of confusion when trying to analyze the performance of explosive products in decked blast designs.

Geologic Considerations in Blasting and Mine Safety
Geology plays a major role in all aspects of a blast’s performance. It has been said that geology is the number one uncontrollable factor to be considered in efficient blast design. In the blast design process, bench heights are often selected based upon requirements of the excavating equipment to be used for rock removal.

Measurement Technology in Mining
The mining industry is moving toward a technology driven optimization process. In this optimization, the "cost centers" such as Drilling, Blasting, Excavation, Hauling and Crushing are seen as interrelated variables in the total cost equation. Electronic initiation systems are one of the emerging technologies that will drive this optimization process.
