an increasing numbcr af biaxial reflectance indicatrixes arc being reported from coals of >arious ranks from around the world (Cook, et ul., 1972: Stone and Cook. 1979; Hower and Davis. 1981; Levlnc and Davis. 19841. The objective of this preliminary study was to examinc a variety of coals from the Peacc Kiver Coalfield to determine if any biaxial reflecting coals are present, and to dcvise a m...

This report is part of an ongoing project, begun in IYX7, drain the district. Most of the coalfield is covered by till which limits exposures to the showline, rivers and roadcuts. Climate is fairly mild and wet, and snowfall is common to update knwledge of the coal basins of Vancouver Island. Limited information exists pertaining to coelmeasures of the Squash crudfield or snh-basin (the terms c...

The Huaibei coalfield is an important coal base and one of the hot spots coalbed methane development in China. Therefore, a detailed understanding gas occurrence great significance. This paper analyzes from perspective multiple-level tectonic control, i.e., regional level, mining area mine level. study deduces that characterized by control. At located southeast margin North China plate, affecte...

Thar desert is located in south-east Pakistan carries 175 billion tons of coal and the biggest coalfield Asia. In this paper mathematical framework developed for accurate estimation power production from available capacity. Annual TWh possible energy period 2020 to 2040 followed by detailed analysis capacity factor Maximizing share percentage total mix at least 40% presented. The findings revea...

The Central Institute of Psychiatry provides extension consultation services at two coalfield hospitals of Bihar, representing the intermediate and central level of health care delivery system. Analysis of data covering a period of one year, from September 1988 to August 1989, revealed significant differences in the utilization pattern of the two centres. The differences relate to the proportio...

Mining subsidence associated with longwall extractions beneath significant natural features such as rivers and streams in the Southern Coalfield of New South Wales has posed risks to the natural environment. In this paper, a case study is presented showing the methodology in two-dimensional UDEC (Itasca 2006) modeling for mining induced subsidence around river valley, taking advantage of the di...

Elevated levels of total dissolved solids (TDS) have been identified as stressors to aquatic life in Central Appalachian coalfield streams. At present there are no aquatic life water quality criteria for TDS in the primary coal-producing Central Appalachian states (KY, VA, WV). In all three states, mining-related impacts on aquatic life have been characterized using measures of benthic macroinv...
