major problems facing the development of coal and gas resources of the hartshorne coalbeds include the complex distribution of minable and unminable coal, high methane content and bed pressure, faulting, variations in degree of dip, presence of natural gas fields in associated sandstones, and legal problems, caused by local geologic characteristics, in identifying gas origin.
important problems of coal mining in india are mentioned below: i. most of the coal deposits occur in the north-eastern part of the indian peninsula. other parts of the country either have no coal deposits or limited reserves of poor quality coal. coal distribution is highly uneven throughout india. ii. coal
when stratified mining is adopted in high-gas and extrathick coal seam, a large amount of pressure-relief gas of the lower layer flows into the upper layer goaf along the cracks in the layer, resulting in upper layer working face to frequently exceed the gas limit. and ordinary drilling can no longer meet the requirements of the pressure-relief gas drainage of the lower layer. the 205 working
there are, however, a variety of problems associated with the use of coal. mining operations are hazardous. each year hundreds of coal miners lose their lives or are seriously injured. major mine hazards include roof falls, rock bursts, and fires and explosions.
the problems arisen in open coal mining by the early 1990s are considered. the structure of productive capacity arrangement, relations between the reserves and the intensity of their mining, quality of produced coals, as well as resource-intensity and replacement of
when companies break up materials during mining, the dust can release a variety of heavy metals commonly associated with health problems. as dust, these minerals (such as the asbestos-like mineral riebeckite) can be absorbed into lung tissue, causing problems like pneumoconiosis and silicosis, commonly known as 'black lung' (paul & campbell, 2011).

one of the most obvious (albeit perhaps least harmful) environmental effects of coal mining is noise pollution. coal mining is a loud, day- and night-long process that disrupts the lives of those in the surrounding communities, reduces the quality of life and can go on for decades. #11 loss of wildlife
there were two big engineering problems in mining coal underground: a system to drain water from the mine. a system to ventilate the mine and to provide fresh air to the miners. a special problem in coal mines was the methane (a gas) that sometimes accompanied coal, and which could--and too often did--catch fire and explode. andrew roy was one
potential mining problems near tectonic faults. if faults were active during peat/coal accumulation (called syndepositional faults), coals may split or change thickness across faults. if faults were active just after peat/coal accumulation, roof rocks may
