Historically, mining companies have tended to operate as focused mineral extractors, supplying their product to the metals commodity markets or under long-term contracts to a small number of customers. Under this model, the key to success has been the ability to secure low-cost resources and manage efficient, stable operations in each location.
Open-pit mine Type of mining that is used for shallow deposits; coal or ore is extracted by digging a succession of benches from the surface of the ground downward. Crater Depression that forms the bottom of the quarry; it is a result of the extraction of .
Coal prices at surface mines are generally lower than prices at underground mines. In locations where coal beds are thick and near the surface, such as in Wyoming, mining costs and coal prices tend to be lower than in locations where the beds are thinner and deeper, such as in Appalachia.
Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped. In best practice a detailed rehabilitation or reclamation plan is designed and approved for each coal mine, covering the period from the start of operations until well after mining .

Mining Cost Model. 5,000 Tonne per Day Open Pit Mine Model. This mine is an open pit mine producing 5,000 tonnes ore and 5,000 tonnes waste per day. The total resource to be mined is 18,715,000 tonnes. Ore is hauled 1,068 meters to an ore stockpile. Waste is hauled 535 meters to a waste rock dump.
Although the United States has the vast coal resource described in the previous chapter, perhaps as much as 4 trillion tons, the key issue for policy makers is the amount of coal that is economically recoverable.This is not a fixed quantity, but depends on the geological resource, the market price, and the cost of mining. The particular characteristics of the coal mining industry create unique ...

Extremely high and volatile metallurgical coal prices since mid-2016 have, after 3-4 years of scrutiny on cost reduction, shifted the focus of the industry away from costs of production – with spot prices spiking to ~200% above average costs of the industry, as they have done twice in the last year or so, changes to operating costs have, inevitably, seemed of little importance.

Also updated dynamic referencing for cost inputs. This financial model takes into account all the general capital costs, employee wages, and supplies required to operate an open-pit mine and sets them against possible revenue so you can see what annual cash flow/break even scenarios look like.
the model hypothesizes a tradeo between safety and productivity. In the model, each mine chooses the level of safety input that balances the marginal cost of having additional safety labor input against the bene ts in terms of lower expected payments from accidents. Thus, mines attempt to maximize pro ts from expected coal
to estimate costs for future coal mining projects within a coal-mining country. The model runs from an MS Excel® spreadsheet and capital costs are estimated to an order-of-magnitude level, which is appropriate for use at a concept study level. With all the cost models, data is .
Labor productivity in the mining industry has been declining rapidly around the world. In the US coal sector, for example, labor productivity declined by an average of 27.5% from 2009 to 2012.
The revised EPRI coal mining cost models represent a computerized approach to the analysis of production costs and mining requirements of either surface or underground mining projects. The models estimate all capital and operating costs typically .

The main mining valuation methods in the industry include price to net asset value P/NAV, price to cash flow P/CF, total acquisition cost TAC & EV/Resources. The best way to value a mining asset or company is to build a discounted cash flow (DCF) model that takes into account a mine plan produced in a technical report

econometric formulation that relates the mine mouth prices of coal for each supply curve to a set of independent variables. The independent variables include capacity utilization of mines, mining capacity, labor productivity, the user cost of capital of mining equipment, the cost of factor inputs (labor and fuel), and other mine supply costs.
Dec 03, 2013· I've actually been through a few of these and agree with the majority of the answers listed here but for one fact. When you value things you typically have three methods: 1. DCF (present value of estimated future earnings from the project) 2. Com...
