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. …

Those involved on commercial minerals processing and metallurgical operations: what are the things that consume most of an operator's/metallurgist's time & energy on a daily, weekly and/or monthly basis?

This question is broad on purpose. Speak from your experience as much as possible.

Thank you in advance!

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

Hi all - what's the biggest thing that will change over the next 15 years in mining? I'm doing some research with the largest survey into innovation in mining, would love to hear your thoughts on what's going to change in your operating environment: stateofplay.org/survey-2018
