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:
The paper presents results of geochemical analyses of organic matter (OM) in a tonstein bed and surrounding bituminous coal from the Upper Carboniferous (Westphalian B) coal seam no. 385/2 from the Bogdanka mine, Lublin Coal Basin. In all studied samples, including those of tonstein and bituminous coal, OM was found to be very similar in composition. Distribution of hydrocarbons in investigated rocks is characterized by strong predominance with odd-number carbon-atom of the long-chain n-alkanes in comparison to the even-number and high concentration of C29 steranes, what implies relatively high input of higher-plant OM in these samples. Minor concentration of C28 steranes and perylene points at presence of fungi. In all extracts, the tri- and tetracyclic diterpanes co-occur with their aromatized derivatives, what suggests presence of the tap resin species - precursors of the conifer families in the plant community. The abundance of sesquiterpanes, pentacyclic triterpanes and benzohopanes indicates a significant bacterial input, most possibly connected with bacterial activity after deposition of terrestrial OM. The original material of tonstein was pyroclastic in orgin, and deposited directly on plants living at the surface of a mire. That material hadn’t had any direct influence on chemicalOMtransformation. The biomarker data, both for coals and tonstein, reveals that sedimentary organic matter was heated up to a temperature corresponding to the level of immature/start of oil window. On the other hand, the increase in thermal maturity value, based on distribution of the aromatic hydrocarbons in organic matter in tonstein (theoretical vitrinite values - Rc, Rcs) are probably due to the presence of incompletely burned organic remains (charcoals), transported to the sedimentary basin along with volcanic ashes.
