Article history Received 1 October 2011 Received in revised form 6 March 2012 As at the end of 2011, total coal resources in Malaysia stood at 1819 Mt, of which 1468 Mt or 80.7% were located in Sarawak, 334 Mt or 18.3% in Sabah, and the remaining 1% in coalfield in 1986.
Abstract Since the Carboniferous, tropical latitudes have been the site of formation of many economic coal deposits, most of which have a restricted range of mineralogical composition as a result of their depositional environment, climatic conditions, and diagenesis. Mineralogical and microscopic investigations of tropical peats from Tasek Bera, Peninsular Malaysia, were performed in order to ...
M.S. Blinderman, ... A. Taskaev, in Underground Coal Gasification and Combustion, 2018 12.10.2 Exploration requirements. Exploration for UCG is different from that for underground coal mining since UCG requires much better understanding of coal geology and hydrogeology. As in exploration for coal mining, the rules and specifications are dependent on local geologic conditions.

Coal is a combustible black or brownish-black sedimentary rock, formed as rock strata called coal seams al is mostly carbon with variable amounts of other elements, chiefly hydrogen, sulfur, oxygen, and nitrogen. Coal is formed when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial over millions of years.

This is the first study that focuses on the evaluation of a newly discovered oil shale deposit in the eastern Chenor area in the state of Pahang, Malaysia. Previously, this deposit was reported as carbonaceous/coaly mudstone. However, in this study, organic-rich immature carbonaceous mudstone containing above 15 wt % total organic carbon (TOC) is evaluated as oil shale, and that below 3.5 wt ...

Coal is mined by both surface or ''opencut'' (or opencast) and underground or ''deep'' mining methods, depending on the local geology of the deposit. Underground mining currently accounts for about 60 per cent of world coal production but around 80 per cent of Australia''s coal is produced from opencut mines.
· Mining Publication: Geologic Hazards and Roof Stability in Coal Mines. The U.S. underground coal miner faces a continuing hazard from the fall of roof. At the root of many injuries and fatalities are weak or defective roof strata. Throughout mining history, millions of miles of entry have provided exposure of every conceivable geologic roof hazard.
