Mining is experiencing an exciting shift, thanks to spatial (or geospatial) data. Spatial data is becoming more detailed and clearer than ever: Threedimensional (3D) Modelling creates a viewable, lifelike impression with depth perception that allows the human brain to understand and relate to complex interrelated issues. 3D modelling supports firms by reimagining the mine more efficiently.

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
Biomining is a technique of extracting metals from ores and other solid materials typically using prokaryotes, fungi or plants (phytoextraction also known as phytomining or biomining). These organisms secrete different organic compounds that chelate metals from the environment and bring it back to the cell where they are typically used to coordinate electrons.
Coal occurs after living materials like plants and animals collect in a swampy region decay and degrade by decomposition of microorganism resulting in solid products, which can produce heat. On the other hand, charcoal occurs after plats, especially woods and plant trumps are exposed to heat and a limited supply of oxygen.

#0183;#32;Coal Coal Problems associated with the use of coal: Coal is abundant. Assuming that current rates of usage and production do not change, estimates of reserves indicate that enough coal remains to last more than 200 years. There are, however, a variety of problems associated with the use of coal. Mining operations are hazardous.
#0183;#32;Strip mining is commonly used for mining coal seams and phosphate beds. In hilly terrain the mining of the overburden and the deposit (usually a coal seam) follows the contour around the hill and into the hillside up to the economic limits; hence it is called contour mining.
mining and deep underground mining are the two basic methods of mining used in South Africa. Approximately 51% of South African coal mining is done underground and about 49% is produced by opencast techniques.
Reported characteristics and ranges of ARD for coal mining operations are summarized in Table 1. Usually, metal mining ARD contains a greater variety of metals, such as copper, zinc, cadmium, arsenic, lead, nickel etc., in elevated concentrations.

#0183;#32;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.

Early coal extraction was smallscale, the coal lying either on the surface, or very close to it. Typical methods for extraction included drift mining and bell well as drift mines, small scale shaft mining was used. This took the form of a bell pit, the extraction working outward from a central shaft, or a technique called room and pillar in which ''rooms'' of coal were extracted with

Coal Mining and Processing | Energy Trends Insider. Heavy machinery is used in mining to explore and develop sites, to remove and stockpile overburden, to break and remove rocks of various hardness and toughness, to process the ore, and to carry out reclamation projects after the mine is closed.

For many years the only microorganism thought to be important in the leaching of metals from ores was the rodshaped bacterium Thiobacillus ferrooxidans. This microorganism was discovered in the acidic water draining coal mines; it was not until 1957 that a correlation was recognized between the presence of the bacterium and the dissolution of metals in copperleaching operations.
