Stripping Ratio Mining Britannica

the break-even stripping ratio is a function of ore value and the costs involved. read more inspire your inbox sign up for daily fun facts about this day in history, updates, and special offers.apr 12, 2018 the break even stripping ratio is that s.r at which the costs of mining the ore and waste are same as the revenue for that block of orecoal. b.e.s.r refers only to the last increment mined along the pit wall. It is calculated for the point at which break even occurs and the necessary stripping is paid for by the net value of the break even stripping ratio given an underground total mining cost of $8.85 per tonne, surface mining costs of $2.95 per tonne of ore, and surface mining stripping costs of $1.75 per tonne of waste, calculate the break even stripping ratio between surface and underground mining.wijaya, kiki gustiawan and idrus, arifudin and wahyu sasongko, wahyu sasongko analisis break even stripping ratio dan desain pit tambang batubara pt.x. in: pit iagi yogyakarta 2012 the iagi annual convention and exhibition, september 2012, yogyakarta.

If the break-even stripping ratio remains favourable, further cuts into the hillside will be made. We divide the overburden thickness by ore thickness to get the stripping ratio for example if we have an overburden thickness of and ore thickness ofgiven an underground total mining cost of $8.85 per tonne, surface mining costs of $2.95 per tonne of ore, and surface mining stripping costs of $1.75 per tonne of waste, calculate the break even stripping ratio lower break-even point the strip straddle will return a loss if price of underlying security upper break-even point and lower break-even point maximum loss is limited to the initial investment and occurs when price

Break Even Analysis How To Calculate The Cut Off Grade

for conducting a mining projects break even analysis, you first need to know about the operational expenses .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 come up with the cost price per tonne if a feasibility study isnt available, refer you mar 30, 2014 setelah semuanya telah diketahui baik volume OB dan tonase bb, maka di gunakanlah rumus striping ratio break even stripping ratio yaitu perbandingan antara keuntungan kotor dengan ongkos pembuangan ob. cost penggalian bijih besr ----- cost pengupasan OB untuk memilih system penambangan digunakan istilah besr-1 bagi open pit yaitu break even stripping ratio adalah perbandingan antara biaya penggalian batubara dengan biaya pengupasan tanah penutup atau merupakan perbandingan biaya penambangan bawah tanah dengan penambangan terbuka. break even stripping ratio ini disebut juga overall stripping ratio, yang dapat dinyatakan sebagai berikutWe divide the overburden thickness by ore thickness to get the stripping ratio for example if we have an overburden thickness of and ore thickness of then the stripping ratio will be

Break Even Stripping Ratio Britannica

In 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.maximum allowable stripping ratio. the maximum allowable stripping ratio is significant because it is purely economic ratio and determines the pit limit at current economic scenario. cost is applied to the physical waste and ore tonnages and that determines the profitability.the maximum allowable stripping ratio defines break even stripping ratio .this represents the highest possible units of waste that can be handled. If the SR exceeds the besr then the operation will be uneconomical as the income generated by the ore is insufficient to offset the costs incurred in mining.may 09, 2020 stripping ratio is a term that is derived from the mining industry and is used in reference to the open-pit mining process. the 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
