This article reviews evidence for the public health impacts of coal across the extraction, processing, use, and waste disposal continuum. Surface coal mining and processing impose public health risks on residential communities through air and water pollution. Burning coal in power plants emits more nitrogen oxides, sulfur dioxide, particulate matter, and heavy metals per unit of energy than ...
Sep 18, 2007· Considering ground instability problems of underground coal mines at shallow covers, this paper reviews and describes problems of optimal extraction of coal stuck below surface/subsurface constraints at Indian coal fields. Importance of thickness and quality of interburden between the working horizon and surface/subsurface constraints is discussed from a ground movement point of view during ...
Frank Matero''s Pit and Quarry: The Cement and Slate Landscapes of Pennsylvania, meanwhile, looks at a region whose history lay in building materials — steel and cement production, coal mining, and slate. He asks how we might best preserve this iconic industrial heritage and these historic extraction .
Determining the optimal extrication location of the high extraction roadway can improve the gas extrication effect of highly gassy mine and solve the problem of gas concentration overrun at the upper corner, which is of great significance to safety and efficient mine production. According to the actual situation of mine, the gas gushing amount in the goaf, pressure difference at both ends of ...
