Some of high rank coal occurrences in Kalimantan Basins-Indonesia have been identified an on of the bituminous umented as coking Coal deposits The occurrence of the coking coal deposits boea y high fluidity, although the atent of inert macerals appears coals in general are dominated by vitrinite macerals with minor inertinite and liptinite contents …
Predominant quartz sandstones in this area belong to the Balikpapan beds. It is light grey to white in color and turned brown in weathered rocks, fine to medium grained, subangular to angular, well bedded sorted and partly with coal grain impurities. Limonitic concretion or limitc coatings were usually found above the quartz sandstone bed. Mudstones…
In the 1960s 'and early 1970s the growth in world seaborne coal trade mainly reflected the increasing • demand for steel. Following the oil shocks of the 970s, the further strong growth in world coal trade been driven primarily by the rapid growth in cctricity generating capacity. Consequently, wh…
Macerals are the microscopically recognizable individual constituents of coal and depending on their quantitative participation and their association, they control the chemical, physical and technological properties of a coal of a given rank. In this new classification (ICCP system 1994) the maceral group has been revised from its previous classific…
Coal, a relatively low-cost fuel that produces significant amounts of pollutants, supplies 18.7% of the Korean economy's energy needs. The total amount of coal consumed in 1995 was 43;6 million tons, and the demand is forecast to increase
3.5% annually by 2010. Of the 43.6 million tons, only 5.5 million tons are domest…
In the past, conventional reflection seismic techniques were not very successful when applied to typical mining exploration:They lacked resolution in the shallow range or were not cost effective. By combining a light earth tamper source, special geophones and field procedures, a stacking process of the returning seismic events using a microprocessor…
52 tons of Indonesian briquetted coke were put through a small blast furnace of friedrichshutte at Herdcorf with the aim of determining the suitability of this coke for metallurgical purposes and thus for the blast furnace. The small blast furnace has a herath diameter of 1.8 m and normally puts through 50 - 60 tons of coke per day corresponing to a…
Mudstones (interbedded clay, silt and very fine grained quartz sandstone) and coal beds were encountered as intercalations in the quartz sandstone beds. Its bedding plane could rather well be measured, morover on the contact rocks. Brown to black clays (carbonaceous clays/shales)nwere found under the coal beds.
These proceedings are a compilation of papers presented at the inaugural APEC Coal Trade and Investment Liberalisation and Facilitation Workshop held in Jakarta, Indonesia on 5 and 6 August 1997. The Workshop Series is being organised by the Australian Department of Primary Industry and Energy (OPIE) and the Japanese Commi…
