1736 Coal mines in Colonial America Several “coal mines” are shown on a map of the upper Potomac River, near what is now the border of Maryland and West Virginia. 1748 First commercial coal production The first commercial coal production in colonial America is recorded near Richmond, Virginia...
Notably given the similarities between coal and lignin, it was anticipated that our coal derived isolates would exhibit ligninolytic potential [75]. Considering the harsh conditions in underground coalmines, it is reasonable to anticipate the isolation of robust ligninolytic bacteria from this environment...
This study aims to provide decisionmakers with scientifically substantiated management recommendations with respect to SOC sequestration through selected available recultivation technologies. Considering that coal mines are currently or will be decommissioned all around the globe, particular emphasis was placed ...
Over the years traffic slowly disappeared as mines closed and timber tracts were exhausted. The B&O lost an important source of traffic via the BC&G after December 30, 1963 when the Rich Mine shut down. The BC&G took another hit in 1965 when the mill at Swandale switched to trucks, ...
plan. Business sense dictates that in such an industry an emergency plan would have been developed for their own safe operation, and for insurance purposes. • Union Carbide developed a town called Uravan. Ore from mines of the surrounding area, rich in uranium and vanadium deposits went to ...
In order to analyze the key points and change trends of the coal mine intelligent policy, it is necessary to screen and collect the text of the coal mine intelligent policy [5,6,7]. In order to speed up the intelligent construction of coal mines, the central and local energy bureaus ...
The underlying mechanisms of the functional roles of bacteria, fungi, and plants in coal-associated sites (abandoned mines, surface coal mines, and post-coal mining activities) and affecting environmental factors are yet to be fully explored; Although recent evidence has implicated the vast potential...
2.3.2 Interactive Resource Tenure Map The Queensland Department of Energy and Mines (DME) maintains the Interactive Resource Tenure Map (IRTM). The IRTM enables the user to search and display mining tenure and exploration information. In particular, it is possible to search and display historic ...
It is usually enough to show through outcrops of coal and/or subsurface drill wells or even the presence of mines that coal-bearing sediments occur. These types of data, even if sparse, establish if there is some continuity of the coal-bearing zone, though specific correlation of coal beds...
Evaluation of water resources carrying capacity in ecologically fragile mining areas under the influence of underground reservoirs in coal mines. J. Clean. Prod. 2022, 379, 134449. [Google Scholar] [CrossRef] Zhang, S.Y.; Wang, H.; He, X.W.; Guo, S.Q.; Xia, Y.; Zhou, Y.X.; ...
