Opportunities for coal to methanol conversion

Description: The accumulations of mining residues in the anthracite coal regions of Pennsylvania offer a unique opportunity to convert the coal content into methanol that could be utilized in that area as an alternative to gasoline or to extend the supplies through blending. Additional demand may develop through the requirements of public utility gas turbines located in that region. The cost to run this refuse through coal preparation plants may result in a clean coal at about $17.00 per ton. After gasifica… more

Effects of the DOE proposals for new source performance standards for utility boilers firing anthracite coal

Description: Currently, the most important expansion market for anthracite is the electrical utilities/power generation area, where the major competitors are other forms of coal. However, anthracite is more expensive to mine than bituminous coal and requires more expensive boilers and other plant equipment. Advantages of anthracite include its geographic location and, most importantly, its low sulfur content and slightly higher heating value relative to bituminous coal. Because of these factors, anthracite … more

Review of subsidence prediction research conducted at Sandia National Laboratories

Description: This paper reviews the results of the subsidence research program at Sandia National Laboratories. The manuscript highlights the following: the application of empirical methods (profile functions) to the subsidence above longwall panels in the US; the use of the rubble model to describe the behavior of broken strata as it distends when it falls to the mine floor (or top of the rubble pile) and then is subsequently compacted as it is loaded by overlying elements of strata; and, the application o… more

Revegetation of Alaskan coal mine spoils. Progress report

Description: Activities initiated after the start of the revegetation project on Alaskan coal mine spoils on September 1, 1979 have consisted mainly of some fall plantings (dormant seedings) and soil and coal spoil samplings and analyses. Because of the late summer start for the project, only a limited amount of field work could be initiated in plant material studies. This consisted of a fall planting at the Usibelli mine site at Healy in interior Alaska. The planting was intended to test the efficacy of se… more

Role of UCG in maximizing coal utilization: site specific study

Description: The Department of Energy is sponsoring a project to develop a planning scheme for improving the utilization of coal deposits. This prototype study, called Total Economic Coal Utilization (TECU), is being applied to specific coal reserves within the Centralia-Chehalis District of Washington State. A significant aspect of the study is to determine the potential role for in situ gasification in maximizing the energy recovery and use. The results obtained indicate that UCG could be used to realize … more

A review of existing models and methods to estimate employment effects of pollution control policies

Description: The purpose of this paper is to provide information about existing models and methods used to estimate coal mining employment impacts of pollution control policies. The EPA is currently assessing the consequences of various alternative policies to reduce air pollution. One important potential consequence of these policies is that coal mining employment may decline or shift from low-sulfur to high-sulfur coal producing regions. The EPA requires models that can estimate the magnitude and cost of … more

Effects of a flexible definition of new source performance standards for utility boilers firing anthracite coal

Description: The primary constraints and incentives affecting the viability of increased anthracite production for use as a utility boiler fuel are related to: (1) inherent advantages and disadvantages of anthracite versus bituminous coal, (2) geographical considerations, and (3) the existing and future state and federal regulatory framework. Anthracite is inherently low in sulfur content (a nominal 0.7% versus 2.0% for bituminous coal) and thus is capable of providing energy in a more environmentally benef… more

Health and safety evaluation of a modified tunnel-borer design for application to single-entry coal-mine development

Description: The health and safety analysis is part of an overall effort to identify and develop innovative underground coal extraction systems. The single-entry tunnel borer system was initially considered an innovative approach to underground mining because it exhibited a means of increasing the speed and efficiency of entry development by reducing the number of entries. However, to be considered a truly advanced system, the tunnel borer had to meet distinct safety criteria as well. The objective was to e… more

Dragline bucket improvement survey. Final report, September 30, 1977-September 29, 1979

Description: An operating dragline bucket receives a lot of abuse. It logs about a million dig cycles every two or three years, all the while operating through abrasive overburden on a round-the-clock basis. It is to the credit of designers, operators and maintenance men alike that these buckets perform so well under such adverse conditions. Comments made in this report are for the purpose of focusing on areas in which further improvements can be made, and in no way are intended to reflect adversely on the … more

Evaluation of European empirical methods for subsidence in US coal fields

Description: The purpose of this study was to assess the applicability of European subsidence methods for the emerging US longwall practice. Subsidence prediction in Europe has typically used either graphical methods (United Kingdom) or mathematical methods. The mathematical methods utilize either profile or influence functions. The graphical methods were developed in the United Kingdom (UK) by the National Coal Board (NCB) from subsidence data obtained from numerous mines. Although a large data base in the… more

Regional Issue Identification and Assessment program (RIIA). Environmental impacts and issues of the EIA MID-MID scenario: Federal Region III (mid-Atlantic)

Description: The EIA MID-MID scenario generally reinforces existing environmental concerns in the mid-Atlantic region. This results in part from the emphasis on existing rather than new energy technologies. The widespread public opposition to nuclear power in the region is likely to impede realization of the nuclear goals of the scenario. About 50% improvement in sulfur oxides air quality is projected for the region (all states), based on emissions reductions both within the region and in neighboring region… more
