Coal mining and transportation U.S. Energy Information
Coal miners use two primary methods to remove coal. Surface mining is often used when coal is less than 200 feet underground. In surface mining, large machines remove the topsoil and layers of rock known as overburden to expose coal seams. Mountaintop removal is a form of surface mining where the tops of mountains are removed to access coal seams.Coal mining, extraction of coal deposits from the surface of Earth from underground. Coal has been used since the Bronze Age, 3,000 to 4,000 years ago, and was the basic energy source that fueled the Industrial Revolution of the 18th and 19th centuries.

W.}, abstractNote = {The revised EPRI coal mining cost models represent a computerized process engineering approach to the analysis of production costs and mining requirements of either surface or underground mining projects.Underground mining, sometimes called deep mining, is a process that retrieves coal from deep below the Earth’s surface—sometimes as far as 300 meters (1,000 feet). Miners travel by elevator down a mine shaft to reach the depths of the mine, and operate heavy machinery that extracts the coal and moves it above ground.Coal National Geographic Society

Activity Based Costing: Challenging the way we cost
The way coal mining systems are currently costed Falconer3 documented a costing approach, which formed the basis for his analysis of costing three underground coal mining methods. In terms of the definition of the costing systems above, the way Falconer conducted his research was based on the traditional costing (Process Costing) This costing system is seen a lot in custom product and service companies. The job order costing system determines the cost of a product or service based upon three components of price. This includes:Manufacturing Costs of Job Order Cost Systems Study

Prices and costs Coal 2020 Analysis IEA
Prices. Coal prices vary by region as well as by grade and quality. The price rebound starting in 2016 ended in 2018, moving in a downward trend in 2019. After stabilisation of prices in the beginning of 2020, Covid-related demand suppression pushed prices down. FOB prices for thermal coal with a calorific value (CV) of 6 000 kcal/kg which hadAuthors conclude that such effects endanger the future of mining companies, therefore reducing production costs would be advisable. Concerning the coal price in China, Li, Zhou, and Lu (Citation 2009) analyse the economic conditions of coal mining and show that total coal cost influences coal prices and optimal resource allocation.
