Mining Construction Mega Projects

Hello All,

I thought it would be worthwhile to have a post that speaks to Mining Construction Mega Projects.  The top 20 mining companies are postured to spend $60B/year on greenfield projects as well as brownfield expansions.  I wasn't able to find any other posts on the topic, therefore would like to ask the community; why do you think 4 out of 5 Mining Construction Mega Projects come in late and over budget by 50%?

Thanks,

Jason

BULK EMULSION IN UNDERGROUND MINING

Hi people around the world

I hope you and your family are safe.

I am working in a research about the application of bulk emulsion in underground mining, I read a lot of information about it and I hope you can help me with your opinions about its application in different mining methods and two question which are : 

What is the three best adavantages of this explosive ?

and

What is the best advance per blast that you obtained from its…

Approach to Estimating Shaft Costs

Hi Everyone...I posted this in the Shaft Sinking Group but thought it might get a lot more exposure and potential input here.

I work for a group that conducts mine cost estimating and we would like to begin updating an article that we publish regarding the costs to sink shafts. Currently, we provide pre-feasibility level estimated costs for a number of diameters (or rectangular dimensions) based on low, medium and hard Uniaxial Compressive Strengths. …

Trolley Feasibility

Hello all,

Just signed up with the group and kudos to Harald for setting this up.

Interested to see if any group members have experience with operating or the technical evaluation of trolley assisted haulage. I am interested in evaluating the technology for our project, but relevant experience seems hard to find.

Looking forward to your replies

Queensland has a rich and seasoned mineral mines and quarry industry. Continuous improvement of occupational safety and health related requirements creates opportunities for embracing more innovative techniques to ameliorate dust related hazards. Bearing testament to the progressive approach to reducing risks associated with respirable dust particles the Queensland Government recently updated guidelines for mineral mines and quarries under the Mining and Quarry Safety Health Act of 1999. The…

Autonomous Haulage - Business Case

Results indicate that cut-offs for the application are presently in excess of 12 Mtpa of total earthmoving. All of the current implementations of an AHS are based in mines that exceed this amount of total material moved.
Truck count cut-off thresholds vary by payload capacity, but a minimum of six to eight trucks is generally required. In its present form, an AHS is therefore not likely to be applicable to all surface mines as scale is a key factor.

The mining boom and political risk

VANCOUVER: After a nine-year lull, investors are fast-taking notice of the once-neglected precious-metals sector. Gold was among 2019’s best-performing asset classes and it was only days into the arrival of the Covid-19 pandemic before the metal regained its USD 1,700/oz footing from a low of $1,471.

On 21 April, Bank of America predicted a gold price of $3,000 per ounce within 18 months suggesting that AU could continue to outperform even if the Covid bear-market continues. In line…

I appreciate the way Emmanuel explains exactly what is the difference between geostatistics and machine learning in a way that is applicable to mining. In particular, this section lays out how the two will come together to be essential for the future of mining.
 

“Recent advances in cloud computing may be allowing geostatistics to crunch more data, faster, but its merging with machine learning techniques that will continue to be the most exciting development in the…
