Activity Based Costing: Challenging the way we cost

costing technique does not work well for multiple products. When one thinks of a multi-product mine producing coal for export and local consumption, it is difficult to separate the mining activity as, for example, a blending operation to obtain the right product may skew the costing analysis. Further, this costing approach does not identify variable/avoidable costs (as these are absorbed into

Coal prices and outlook U.S. Energy Information

The higher cost of coal from underground mines reflects the more difficult mining conditions and the need for more miners. When coal is burned, it releases impurities that can combine with oxygen to form sulfur dioxide (SO2). When SO2 combines with moisture in the atmosphere, it produces acid rain that can harm forests and lakes. Because of environmental regulations limiting sulfur emissions

Drift mining Wikipedia

Drift mining is either the mining of an ore deposit by underground methods, or the working of coal seams accessed by adits driven into the surface outcrop of the coal bed. A drift mine is an underground mine in which the entry or access is above water level and generally on the slope of a hill, driven horizontally into the ore seam. Random House dictionary says the origin of the term "drift

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. 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 has finished. Underground mining. There are two main

Underground mine ventilation Wikipedia

Underground mine ventilation provides a flow of air to the underground workings of a mine of sufficient volume to dilute and remove dust and noxious gases (typically NO x, SO 2, methane, CO 2 and CO) and to regulate temperature.The source of these gases are equipment that runs on diesel engines, blasting with explosives, and the orebody itself.

MINE VENTILATION SYSTEMS

In the U.S., as well as in the rest of the world, mine ventilation practice is heavily regulated, especially in coal and gassy (noncoal) mines, and other statutes relate to air quantities required to dilute diesel emissions, blasting fumes, radiation, dusts, battery

Mine Rehabilitation and Closure Cost

Large open cut mines can cost hundreds of millions and some cases over a billion dollars to close.

A mining company purchased a coal mine on Jan 1 20X5 for $2,800,000. The estimated capacity of the mine is 1,750,000 tons of coal and the estimated salvage value is zero. The company incurred additional $50,000 on development of mine for extraction purposes. They had extracted 210,000 tons of coal from the mine up to Jan 31, 20X5 and sold all but 13,000 tons of the coal extracted from the mine
