This study is part of the Coal Quality project, and involves washability characteristics of British Columbia coals. The first two parts of the project involved collection and analysis of washability data from assessment reports (Holuszko and Grievr:, 1990; Holusrko, 199 I ). The washability characteristics of coals from different regions, geological ftwmations and seams were studied wing classi...

Section III of the text discusses the method we use to calculate a coal price index. Here we report the regression results for each region (see Table A.1). We also show the national average for comparison. While the type of coal a power plant purchases may change in response to natural gas prices, we are concerned that the heterogeneity in coal transactions within a plant may also reflect noise...

The effective production of high-quality anthracite has attracted increasing global attention. Based on the coal occurrence in Yongxia Mining Area and mining conditions of a coalface in Xinqiao Coal Mine, we proposed a systematic study on the technical support for the production of high-quality anthracite. Six key steps were explored, including coal falling at the coalface, transport, undergrou...

The Olang area is a part of Gheshlagh-Olang synclinal, which is a member of eastern Alborz coal basin and is situated at a distance of70 km northeast of Shahroud city. Coal-bearing strata of this region are part of the Shemshak group (Upper Triassic to Lower Jurassic).Samples from the 9 coal seams of the Olang coal deposits were collected and ashed. The aim of this study is to determine theoccu...

Until recently, it was conventional wisdom that ‘clean coal’ meant abandoning high sulfur coal resources, reducing plant efficiencies and increasing costs. ZECA Corporation is developing a new ‘Zero Emission’ technology that was invented at Los Alamos National Laboratory. It may stand this preconceived notion on its head. The ZECA Technology has the potential to readily accept high sulfur coal,...

This paper describes the application of innovative hydrothermal technology on local municipal solid waste (MSW) to produce low chlorine content solid co-firing fuel with coal. Raw MSW was treated at temperatures ranging from 210 to 235°C with 30 to 90 minutes holding period. The process yielded slump products which were then naturally dried to 5% moisture content, resulted in dry products with ...

The presence of methane in coal mines is one of the major problems in underground coal mines. Every year, in underground coal mines, a lot of casualties due to outbursts and explosions of methane gas is occurring. Existence of this gas in the mines not only creates a difficult and dangerous situation for work but also makes it more expensive. The release of this gas to the air causes a further ...
