Analysis of sensitivities of local socioeconomic impacts to variations in types and rates of coal development and to differences in local site characteristics

Description: For any given coal project, certain site-specific factors presage the nature and magnitude of the accompanying changes in population and employment. Proper attention given to these factors before energy facilities are sited can do much to mitigate socio-economic impacts. For instance, in those counties where these economic and demographic factors indicate a high susceptibility to impact, the severe cycles of ''boom-bust'' growth conditions can be moderated considerably by me… more

Update on Use of Mine Pool Water for Power Generation.

Description: In 2004, nearly 90 percent of the country's electricity was generated at power plants using steam-based systems (EIA 2005). Electricity generation at steam electric plants requires a cooling system to condense the steam. With the exception of a few plants using air-cooled condensers, most U.S. steam electric power plants use water for cooling. Water usage occurs through once-through cooling or as make-up water in a closed-cycle system (generally involving one or more cooling towers). According … more

Application of a damage model for rock fragmentation to the Straight Creek Mine blast experiments

Description: Early attempts at estimation of stress wave damage due to blasting by use of finite element calculations met with limited success due to numerical instabilities that prevented calculations from being carried past the fragmentation limit. More recently, the improved damage model PRONTO has allowed finite element calculations which remain stable and yield good agreement between calculated fragmented regions and excavated crater profiles for blasting experiments in granite. Application of this dam… more

In situ determination of desorbable methane content by use of three different decay functions

Description: The desorptive properties of methane in selected western coal seams were studied through actual field measurements using a manual bubble desorbometer and later verified through laboratory modeling. Data were reduced using a power decay function, a quadratic function, and an exponential function. Methane desorption characteristics from individual coal seams were shown theoretically to be a good estimator of a seams total methane content to within {plus minus}20%. A laboratory was set up and equi… more

Impact of petroleum industry horizontal divestiture on the coal market. [Proposed for consideration by Congress]

Description: The US Congress has set forth proposals which would prohibit oil companies from acquiring coal companies or other non-petroleum energy resources. Some proposals would require oil companies to divest themselves of any such resources that they already hold. The first legislation was introduced on this topic in the 94th Congress and alternative proposals are under serious consideration at the current time. We have analyzed some major variants of these legislative propsals with a study of likely ec… more

Directory of coal production ownership, 1979

Description: Ownership patterns in the coal industry are highly complex. Many producers are diversified into other lines of activity. The pattern and extent of this diversification has varied through time. In the past, steel and nonferrous metals companies had major coal industry involvement. This is still true today. However, other types of enterprises have entered the industry de novo or through merger. Those of greatest significance in recent times have involved petroleum and particularly public utility … more

Water effects of the use of western coal for electrical production

Description: Water may be a constraint on the expanded development of coal resources in the semi-arid western United States. Water allocation in the West has been determined by the appropriative rights doctrine which allows perpetual use of water sources by those who first claim it for beneficial purposes. This has had the effect of placing a dominative interest in water allocation in one economic sector: agriculture. New water sources are available to coal producers but political and economic problems must… more
