Coal


Book Description

Coal will continue to provide a major portion of energy requirements in the United States for at least the next several decades. It is imperative that accurate information describing the amount, location, and quality of the coal resources and reserves be available to fulfill energy needs. It is also important that the United States extract its coal resources efficiently, safely, and in an environmentally responsible manner. A renewed focus on federal support for coal-related research, coordinated across agencies and with the active participation of the states and industrial sector, is a critical element for each of these requirements. Coal focuses on the research and development needs and priorities in the areas of coal resource and reserve assessments, coal mining and processing, transportation of coal and coal products, and coal utilization.

The Analogy and Differences Between Coal Slurry Transport Systems and Hydraulic Dredging


Book Description

The oil crises in 1973 and 1978 caused many countries to initiate a diversification policy for power generating fuels to reduce their dependence on oil. A renewed interest in the utilization of coal appeared, and around 1980 the prospects for the future use of coal were very optimistic. Although this optimism has since been considerably reduced, steam coal consumption is expected to rise steadily and thus the export and import quantities of coal. As a result, the transshipment and further transport capacities are expanding. One possible method of transporting coal is by pipeline, where a differentiation should be made between long distance fine coal transport and short distance coarse coal transport. Slurry handling of coal has many similarities, but also substantial differences, when compared with the hydraulic handling of solids in the dredging industry. In this paper long distance fine coal slurry and short distance coarse coal slurry transport will be discussed as well as the similarities and differences when compared with hydraulic transportation of solids in the dredging industry. As a coarse coal system, a slurry unloading terminal will be discussed in more detail.
