Coalbedmethane is increasingly playing a major role as a gas resource in the United States, Presently, about eight percent of the total annual natural gas produced in the United States is coalbed methane (fig. I). Coalbed methane was originally thought to be economicallyproduced only from high-rank coal. However,with the advent of economic coalbed …

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…

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.
