Jan 01, 2017 Daily expenses such as chemical and electricity costs are listed as operational expenses. The authors found that maintenance costs varied for each mine site and ranged between 0.2 and 1.45 of total capital costs. Therefore, this analysis used the median value of 0.83 of total capital costs when estimating the maintenance cost.

The mine made some small changes to increase the flow of oxygen, which, as predicted, generated a significant yield gain. The increase in yield translated into a sustainable 10 million to 20 million annual profit improvement, with no need for substantial capital outlays or reorganizations.
A tangle of undercapitalised companies are coming forward to cash in on old deep coal mines in Wales, writes Guy Shrubsole - by digging them all out from above from huge open cast pits.

Aug 23, 2019 In the current study, we investigated a total of 74 open-cast mining projects and forecasted their mining capital cost. Based on confident, fixed and capable elements representing most of the mines, we have developed six AI models that can accurately describe and predict mining capital cost for the mines.
