The formula for break-even analysis is as follows: Break-Even Quantity = Fixed Costs / (Sales Price per Unit – Variable Cost Per Unit) where: Fixed Costs are costs that do not change with varying output (e.g., salary, rent, building machinery) Sales Price per Unit is the selling price per unit. Variable Cost per Unit is the variable cost ...

Stripping ratio is the ratio of the volume of waste rock stripped off to the volume of ore exploited during the process of surface mining. It indicates the volume of waste rock required to be stripped for mining per cubic ore. Stripping ratio (see Fig. 1) is an important technical-economic indica-tor in open-pit mining, which reflects the eco ...

Langkah 3: Hitung Stripping Ratio. Setelah mengetahui volume tanah dan volume batubara, langkah terakhir adalah menghitung stripping ratio. Stripping ratio dapat dihitung dengan menghitung rasio antara volume tanah yang harus dibuang dan volume batubara yang dapat diperoleh: Stripping ratio = volume tanah : volume batubara.
The maximum stripping ratio, which is also known as the breakeven stripping ratio, is an economic calculation based on the cost of removing the overburden and the value of the coal or ore that is exposed when the overburden is removed. Thus, given the stripping cost and the value of the exposed ore, we can calculate the breakeven or maximum ...
The Instantaneous Stripping Ratio (ISR) is the stripping ratio for a given push back, where a tiny slice of material, i.e., ore and/or waste, is removed from a pit wall.
