Coal mining under the sea has been carried out in many different parts of the world. The first consideration associated with undersea mining or for that matter under bodies of water or under subsurface aquifers, is to limit disturbance of the strata above the working faces, in order to prevent water entering the working areas.
10 Challenging Problems in Data Mining Research. In October 2005, we took an initiative to identify 10 challenging problems in data mining research, by consulting some of the most active researchers in data mining and machine learning for their opinions on what are considered important and worthy topics for future research in data mining.
Most countries require reclamation of mining sites, to undo the environmental damage. ... especially in South Africa where the problem has been ignored for over 100 years. ... I am pleased with the good work you are doing can i get an information on small scale mining. Reply. Sandile.
Solutions to Mining Industry Risk Challenges. The very nature of mining natural resources means that many businesses will have operations in some of the most remote and inhospitable areas in the world and very often coupled with a high susceptibility to natural catastrophe. In .

Top challenges faced by the mining industry and its implications (Part 1) An interconnected system is needed as models should account for consideration of the sources (ground water, surface water, public supply), complete water usage (process control, dust control, recycling, potable water) and external factor patterns (hydrologic environment, evaporation, precipitation, snow melting).
INTRODUCTION TO MINING ... It should be noted that the mining engineer is associated with the extraction of nearly all these mineral resources. However,the production of petroleum MINING TERMINOLOGY 3. and natural gas has evolved into a separate industry with a specialized
Highlights. Elemental beryllium has a wide variety of applications. Occupational exposure most often occurs in mining, extraction, and in the processing of alloy metals containing beryllium. Beryllium can cause sensitization, lung and skin disease in a significant percentage of exposed workers.
the missing ethics of mining There is a maddening futility about speaking of "mining," as if it were singular or coherent. It is like talking about "Africa" or addressing the "international community" in the fashion of humanitarians, as if it is all one big thing.
Coal mining deep underground involves a higher safety risk than coal mined in opencast pits, due primarily to problems associated with mine ventilation and the potential for mine collapse. However, there are safety risks associated with all forms of coal mining, not least because of the heavy machinery utilised in coal excavation.
Overexposure to excessive noise can result in tinnitus (ringing in the ears), sleep disturbances, concentration problems and even permanent hearing loss," Clark explains. To protect workers against noise, mining companies should evaluate working conditions and .
Acid mine drainage is a major problem with many hardrock mines, including almost all mines where the metal ore is bound up with sulfur (metal sulfide mines). A significant number of coal mines also suffer from acid mine drainage.
Mining and burning coal for fuel is harmful to the environment; but, because coal is so abundant and cheap, many people are reluctant to give it up as a fuel source. ...

The current turbulence in the mining industry in South Africa has its roots in several different factors. First, the fall in global demand for platinum and other minerals due to recession; second, the consequences of the Marikana disaster in destabilising labour relations; .
The Southern African Institute of Mining and Metallurgy Surface Mining 2008 S Yirenkyi Page 182 Some of the effects of surface mining identified were: 1. Relocation/Resettlement of host communities and its negative effects; 2. Disturbance to Flora and Fauna; 3. Disturbance to Sacred Places; 4. Land Degradation; 5. Noise and Air Pollution; and 6.
Mining industry in Africa is making TB epidemic worse. They found that both the number of mines in a country and the presence of a mining sector that was larger than the African average strongly influenced the number of incident TB cases. Mining for gold was strongly associated with a higher TB burden, regardless of a country's HIV prevalence, probably due to much higher silica exposure in gold mines.
The rationalization of mining activities in many countries has resulted in a high turnover of mineworkers, particularly affecting older, more experienced workers. This has led to a loss of institutional memory. More intensive working, including extended shifts, has become a prerequisite for economic survival.
The environmental impact of mining includes erosion in ... (2014) provide an overview of the lifecycle wide environmental impacts of metal production associated with 62 metals in ... Dissolution and transport of metals and heavy metals by runoff and ground water is another example of environmental problems with mining, such as the ...
The dangers that occur in mining include accidents which have resulted in significant loss of life over the years, as well as health hazards that miners face on a day to day basis. There have however been significant strides in recent years to improve the working conditions for miners, and to create a safer, healthier work environment.
Abandoned mine lands (AMLs) present serious threats to human health and the environment. Addressing AML impacts is becoming increasingly important due to increased exposure to people and risks of accidents, injuries, and tort claims.
Problems in coal mining. If the coal seam reaches a fault, the seam may be significantly displaced, depending on the type of fault and its offset. Machinery trying to mine the coal may not be able to reach the displaced seam, if the displacement is too large. Coal mines use a combination of boreholes and highresolution seismic reflection data...
