Question: You own a coal mining company and are considering opening a new mine. The mine will cost $119.6 million to open. If this money is spent immediately, the mine will generate $20.1 million for the next 10 years. After that, the coal will run out and the site must be cleaned and maintained at environmental standards.

Key Findings. Open-cut or surface mines are the most visible sign of coal mining in Australia, and the country's largest coal mines are getting larger. Increasing strip ratios – the amount of overlying rock that has to be removed to expose the coal seam – are contributing to higher costs for miners and increased emissions.

Historical data collected in various coal-producing countries indicate a general upward trend in the cost of building coal mines. In general, the cost of such facilities ranges from 30 to 80 million euros per 1 million tons of coal per year, so the cost of even small projects can easily exceed 100 million euros.
