Land subsidence caused by coal mining is a most harmful, most widespread and most prolonged geological hazard in mining areas of western China. It also seriously affects water environment in that it not only destroys hydrogeological conditions and changes water cycle patterns but also sharply reduces...
The origins of the termgreenhouse effectare unclear. French mathematicianJoseph Fourieris sometimes givencreditas the first person to coin the termgreenhouse effectbased on his conclusion in 1824 that Earth’s atmosphere functioned similarly to a “hotbox”—that is, a heliothermometer (an insulated ...
EFFECT OF COAL TYPE ON ENTRAINED GASIFICATION (AXISYMMETRIC, PROFILE). The effect of coal type for four coals of varying rank was studied in an entrained flow gasifier, which was modified to increase residence time, to reduce ... BW Brown - Brigham Young University. 被引量: 0发表: 1985年...
The effect of each greenhouse gas on Earth’s climate depends on its chemical nature and its relative concentration in theatmosphere. Some gases have a highcapacityfor absorbing infrared radiation or occur in significant quantities, whereas others have considerably lower capacities for absorption or occ...
The effect of the coal macerals, mineral matter and coalrank on the carbon dioxide adsorption of the samples was evaluated. The coal samplescovered a maturity range from 0.69 % to 2.28 %. The maceral compositions of thefractions varied from 92.8 % to 0.4 % vitrinite and 78.8 % to 0.4 %...
Under this present study, thermal and mechanical behaviors dependence of insulating fire bricks (produced by burnout process) on coal percentage (mass %) were investigated. Waste coal powders or coal dust were collected from mines, transport vehicles, storage areas etc. Specimen insulating bricks were...
Microbial depyritization of coal was carried out in stirred tank batch reactors in presence of an iron-free 9K medium. The results indicate that microbial depyritization of coal using moderate thermophiles is an efficient process. Moreover, particle size of coal is an important parameter which ...
Dilip Kumar, Deepak Kumar, in Sustainable Management of Coal Preparation, 2018 13.2 Health Hazards Noise has become a serious problem in the industrial environment. Different people have different sensitivities to the same noise and are affected differently. The detrimental effects on people may be cl...
