Burden Distance Effect on Fragmentation

Definition of Burden
Burden is defined as the horizontal distance from the front of the blast hole to the nearest free face of rock. It plays a crucial role in determining how effectively explosive energy is utilized during blasting operations.

Burden and Spacing
Burden is closely related to spacing, which is the distance between adjacent blast holes. Together, these factors influence the distribution of explosive energy throughout the rock mass. Optimal burden and spacing ensure that energy is eff

From miners to material providers: making the energy transition a reality

Carly Leonida and Peter Bryant explore the challenges, opportunities and potential impacts on mining of the global shift towards a material intensive energy system

Mining’s role in accelerating the hydrogen economy

Pitt says Resources sector helps Australia’s economy weather the storm of COVID-19

Mining profits attained a record $55 billion, or close to $600 million per day in Q2, 2021 according to the Australian Bureau of Statistics (ABS), despite lagging economies in other sectors.

Turning mine sites into carbon vaults

Dr Alison Shaw explains how a carbon sequestration project developed and initiated by De Beers at its mines sites, could eventually help to mitigate climate change on a much larger scale

Australian Government: "Keep Digging"

Despite all the new regulations and restrictions to flatten the curve of the COVID-19 outbreak, the Australian government has sent a clear message to all miners to continue digging in order to keep one of the country's biggest export industries operating. State and federal ministers agree that the resources sector is essential in maintaining a strong Australian economy.

Recognition of a widespread Paleoproterozoic hydrothermal system in the southern McArthur Basin, northern Australia

The Paleoproterozoic hydrothermal system in the southern McArthur Basin, northern Australia, played a key role in the formation of the world-class clastic-dominant (CD)-type McArthur River Zn-Pb deposit, as well as several small-sized deposits nearby in this basin. However, the spatial scale of this hydrothermal system and its role in controlling mineralisation are uncertain. Such understanding is crucial for improving mineral exploration efficiency. In this study, we characterised the geochemis
