Surface mining planning and design of open pit mining 1.This material is intended for use in lectures, presentations and as handouts to students, and is provided in power point format so as to allow customization for the individual needs of course instructors.Permission of the author and publisher is required for any other usage.
This process continues on the section until the pit limit is set at a point where the calculated stripping ratio and breakeven stripping ratio are equal.In fig.2, the grade on the right side of the pit was estimated to be 0.6 cu.At a price of 2.25 per kg of copper.

MoreCoal resource availability, recoverability, and economic.For example, the current maximum depth for underground coal mining is.Between an analysis using a break-even economic hurdle and inclusion of at least 1 or 2 percent profit to technically meet the definition of reserves is minor, especially for evaluations extensive, very thick, low stripping ratio resources in the prb.
MoreIfric 20 considers when and how to account separately for these two benefits arising from the stripping activity, as well as how to measure these benefits both initially and subsequently.Ifric 20 only deals with waste removal costs that are incurred in surface mining activity during the production phase of the mine production stripping costs.

MoreFor conducting a mining projects break even analysis, you first need to know about the operational expenses opex.When the opex is known, you can calculate the minerals cut off grade, which is the break even grade, below which it is not economically viable to mine the ore.To find out how i come up with the cost price per tonne opex if a feasibility study isnt available, i refer you.
MoreFor surface mining, the stripping ratio and ore grade were determined to be key parameters that combined to contribute approximately 80 of the uncertainty for the land transformation factors of nickel metal.For underground mining, the ore grade and backfilling.
MoreIn this paper,according to the actual example that decides open-pit boundary of a coal deposit,a new formula is deduced that calculates boundary stripping ratio.This new method is superior to the traditional method of calculating pit limit stripping ratio,it is simple.

MoreYes, a 31 stripping ratio means that mining one cubic meter of ore will require mining three cubic meters of waste rock.Calculation of break-even point.
MoreIn coal mining contour strip mining.If the break-even stripping ratio remains favourable, further cuts into the hillside will be made.Otherwise, if there are sufficient reserves under the knob of the hill, the coal may be recovered by underground mining or by augering.
MoreIt should be noted here that a stripping ratio of 2 to1 means t hat there is twice as much waste rock mined as mineral ore, coal, etc.Two types of methods may be used in surface mining.

MoreThe stripping ratio method of calculating the profitability of the mining procedure is commonly used in the ore or coal mining process.In relation to its application in the mining of ore, the utility of the stripping ratio is the determination of the approximate ratio of waste material that must be moved in order to reach a certain ratio of ore.
