When coal seams are near the surface, it may be economical to extract the coal using open cut (also referred to as open cast, open pit, mountaintop removal or strip) mining methods. Opencast coal mining recovers a greater proportion of the coal deposit than underground methods, as more of the coal seams in the strata may be exploited
Open-cast mining continues near a fire at Jharia in India A coal-seam fire is a natural burning of an outcrop or underground coal seam . Most coal-seam fires exhibit smoldering combustion,  particularly underground coal-seam fires, because of limited atmospheric oxygen availability.
About 40 percent of the world’s coal mines are the more damaging strip mines (also called open cast, open pit, mountaintop or surface mining). Strip mining impacts. Strip mining is highly destructive. Yet the industry often prefers to strip mine because it takes less labour and yields more coal than underground mining.
Sub-bituminous coal, Bituminous coal and Anthracite. Open cast mining and underground mining (room pillar, long wall, drift, shaft, slope mining) are some types of coal mining. Proper Environment impact assessment of coal mining is very important and here we take some issues which should be considered and some
Strip mining. Strip mining (also known as open cast, mountaintop or surface mining) involves scraping away earth and rocks to get to coal buried near the surface. In many cases, mountains are literally blasted apart to reach thin coal seams within, leaving permanent scars on the landscape as a result.

Open pit mining. Open pit mining, where material is excavated from an open pit, is one of the most common forms of mining for strategic minerals. This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined.

The current paper reviews published evidence on the public health impacts of surface coal mining. Particular attention is paid to recent evidence for a form of surface mining practiced in the United States, namely mountaintop removal mining. Studies from other parts of the world are also briefly described.
A major part of iron ore, non-ferrous metals, brown coal, building materials and minerals for industry is being excavated in open-cast mines. This type of mining has a deep impact on the natural strata. Open-cast mining changes geological, hydrological and geotechnical conditions. It influences the existing ecological system and landscape.
Dust control practices in the Indian mining industry Jai Krishna Pandey cause of these health hazards to miners. Indian coals are considered to be of 'drift' origin and therefore for settled dust which becomes airborne in favourable condition e.g. haul roads of open cast mines.
When coal has been extracted from the area, the roof is allowed to collapse. Over 75% of the coal in the deposit can be extracted from panels of coal that can extend 3km through the coal seam. Technological advancements have made coal mining today more productive than it has ever been.
15-9-2014· Coal mining companies predictably argue that they are better job creators than agriculture and tourism, but even the biggest mines employ surprisingly few people full-time. Many of the new coal mining projects are short-term, with life-of-mine projections of between three and five years, and maximum employee numbers of less than 100 people.
