Bursa-Orhaneli coalfield
Turkey
Opis:
Bursa-Orhaneli lignite coalfield is located in the North-West of Turkey. This coalfield has three sectors: Burmu, Çivili, and Sagirlar, having similar stratigraphic sequences in the northwest of Bursa Province. The mined coal seam is Miocene of age, and its thickness varies between 1.10-14.50 m. The pre-Neogene rocks in the area are made up of Palaeozoic aged metamorphic schists and marbles, and Upper Cretaceous aged ophiolites. The Neogene formations of detrital rocks with basal conglomerates, coal bearing marl and tuffites are found at the base, and volcanic basalt tuffs and andesite lava flows, at the top. The post-Neogene sediments are Pleistocene aged gravels and Holocene alluvium.The deposit has been worked as an open-pit mine in the Burmu and Sagirlar sectors and is going to be worked by underground mining methods in the near future. The chemical analysis have shown that the percentage of water is 22.66-27.30%, ash 24.57-44.39%, volatile matter 18.52-29.44%, fixed carbon 23.87-29.52%, and total sulphur 1.84-2.64% in the original coal, and its calorific value is 2010-3032 kcal/kg, whereas the air dried coal is composed of 5.51-10.41% water, 26.99-54.18% ash, 21.83-35.49% volatile matter, 28.10-36.03% fixed carbon, and 2.42-3.06% total sulphur, with calorific value of 2483-3938 kcal/kg. The proven and workable lignite reserves are 60,877,079 and 47,308,406 tonnes respectively. Stripping and production operations are made by a dragline, excavators and trucks. Mined coal is used both in domestic heating and the Orhaneli thermic power plant, which has a capacity of 1x210 MW.

Opis:
The paper presents the methodology of economic evaluation of coalbed methane exploitation in coal mines. The methodology consists of seven phases, which analyse: gassy conditions of coal deposit, coal exploitation scope, ventilation conditions of underground workings, productivity of degasification system as well as economics of both coal exploitation and methane recovery. In the result of the analyses classification, of methane resources and their subdivision into economic reserves and potentially economic resources can be done on the ground of either economic findings or methane content figures. The analyses also show, that methane extraction is always economic, but it can be proved only, if profit resulted coal exploitation during degasification is taken into account.

Bogdanka coal mine
Opis:
During the early part of 1999 Steffen, Robertson and Kirsten (UK) Ltd (SRK) were commissioned by Price Waterhouse Coopers to carry out the technical due diligence study of the Bogdanka Coal Mine as part of their contract with the Treasury Ministry of Poland for pre-privatisation analysis. A visit was undertaken by four experienced consultants specialising in the fields of geology, mining, coal preparation and environment. The team also undertook a review of management, manning levels, performance and other broad issues affecting the operation of the mine. In this paper the author outlines the general geology of the mine, and attempts to show how an experienced consultant comes to terms with a meaningful assessment of a mine and coalfield of which he has little or no previous knowledge, particularly given the very short time available for the commission.The relevance of such aspects as mineral rights and concessions, the exploration history, cover deposits, coal bearing strata, geological structure, coal quality and potential hazards to the assessment will be examined. The assessment of reserves and resources to standards acceptable to international banking organisations will be looked at in more detail. Finally some of the critical non-geological factors of the assessment will be outlined.

Opis:
On the turn of the 1980s and 1990s several unfavourable events affected the Polish hard coal mining. Critical for the mining sector were breakdown of the country's request for energy and drop of coal prices on the world market. In the period of 1989-1998, Poland's economic reserves (balance sheet resources) of hard coal decreased by 17%, and the industrial reserves dropped by 41%. Simultaneously, there was and there is still in progress a programme of technical and economic restructuring of the hard coal mining. According to the restructuring programme of coal mining, the total yearly output of Polish hard coalmines will drop from 101 million t in 2003 to 80 million t in 2020. However, there should be taken into consideration that in consequence of 2003-2020 liquidation of consecutive coalmines, ceasing of mining of the coal balance sheet reserves contained in seams below 1.50 m thick as well as other factors may limit the recoverable reserves of coal. In this context, it is highly possible that in the period 2010-2020 the availability of coal resources will be one of the critical problems of hard coal mining in Poland.
