In surface mining, the ground covering the coal seam (the overburden) is first removed to expose the coal seam for extraction. The elements of a surface mining operation are (1) topsoil removal and storage for later use, (2) drilling and blasting the strata overlying the coal seam, (3) loading and ...
Coal Cost Guide Benefits - CostMine - Your Mining Cost Data .... To get that information, many of them turn to Mining Cost Service and now, the 2013 Coal Cost Guide. The Coal Cost Guide is ...Mine and Prep Plant Cost Models.
Abstract. Large-scale surface coal mining will play a key role in meeting the future energy needs of the U.S., especially in affecting the costs of coal conversion and advanced combustion processes being developed by ERDA.

In the second part, two basic methods of extracting coal, i.e. surface mining and underground mining, are introduced. Firstly, two main methods—strip mining and open-pit mining—of surface mining are discussed. In underground mining, room and pillar, shortwall, and longwall mining …
Coal Cost Indexes. Surface and underground coal mining and coal processing. Cost indexes provide a means of adjusting outdated cost information for the effects of inflation. They are based on statistical averages of costs for specific items and time periods.
The guide provides coal-specific estimating information similar to the Mining Cost Service. Along with sections such as Taxes, Wages and Supplies, it includes: Mine & Prep Plant cost models; Coal production data; Mine & Processing Equipment prices; Cost Indexes for Coal Mining

Coal companies use two methods to mine coal: surface mining and ... it goes to a preparation plant for cleaning. The plant removes rock, ash, sulfur, and other impurities ... Deciding how to ship coal is very important because it can cost more to ship it than to mine it.
The coal is then loaded on to large trucks or conveyors for transport to either the coal preparation plant or direct to where it will be used. Mine rehabilitation. Coal mining is only a temporary use of land, so it is vital that rehabilitation of land takes place once mining operations have stopped.
• Two different mining techniques –surface & underground Surface mining is cheaper • Coal seam must be no deeper than 60 m (200 ft) • Accounts for 2/3 of U.S. production but only 40% of world production • Coal typically must go to a preparation plant to increase its heating value • Shipping costs frequently more expensive that ...
Coal deposits Prospecting and exploration Choosing a mining method Surface mining Underground mining Coal preparation Coal transportation. There are several methods for moving prepared coal from the mine to the markets. The cost of transport can be substantial and can account for a large fraction of the total cost to the consumer.

Coal Handling Preparation Plants (CHPP) Mining Industry The cleaner the coal is able to become, the higher the market value will be, plus less waste material means less weight, resulting in lower overall transportation costs.
The important economic parameters are the relative costs of mining coal by surface and underground methods including costs associated with any site-specific land use constraints, the cost of removing the material above the coal seam in the surface method, and the price of coal.
