Ewolucja prawnej regulacji dotyczącej korzystania z zasobów naturalnych wnętrza ziemi w kontekście przemian ustrojowych w Polsce
(Wydawnictwa AGH, 2010) Mikosz, Ryszard
The article concerns the most important legal changes, which after the year 1989 on hale taken place in the field of using the natural resources, located inside the Earth. Its main aim is to present the connection between these changes and the transformation of the legal system in Poland. This connection seems to be indubitable, although one often does not realize it clearly or to the satisfactory extent. The matter is considered on the example of the evolution of the regulation of the geological and mining law concerning: property of mineral deposits, licensing on searching and excavation of these deposits, as well as charges and liability for damages connected with this activity.
Międzynarodowe klasyfikacje zasobów złóż kopalin
(Wydawnictwa AGH, 2010) Nieć, Marek
Three main resources and reserves classifications, internationally recognized are: United Nations Framework Classification of Resources/Reserves (UNFC), CRIRSCO for solid mineral commodities and PRMS for hydrocarbons. The most universal is UNFC formulated within UN Economic Commission of Europe. It allows comparison of varied used national and institutional classifications and present resources data in uniform manner. Its application is recommended by UN Economic and Social Commission (ECOSOC resolution 2004/233). In the UNFC resources are classified on the basis of three criteria: economic and social viability (E), feasibility status (F) and geological assurance (G). Each of them is categorized using numerical coding system. The combinations of particular categories form classes of resources designed by three digit symbol representing EFG categories respectively. Polish classification is based on similar rules as UNFC, CRIRSCO and PRMS and with some assumptions respective classes of UNFC can be found. The substantial difference is the mode of presentation of resources and reserves data: hierarchical in the Polish classification and complementary in UNFC (as well CRIRSCO and PRMS). In Polish resources inventory, according to international rules should be presented separately: industrial, not industrial resources and supposed economic (balance) resources not subdivided to industrial and not industrial.
Ryzyko i niepewność a koncepcja kompleksowego zarządzania złożem
(Wydawnictwa AGH, 2010) Byrska-Rąpała, Alicja
Risk and uncertainty are associated with each part of the projects' life, from exploration, by development, production to abandon. Level of risk and uncertainty result from owned knowledge about deposit and state of reconnaissance in investment projects' surroundings. The main aim of this article is to discuss the concepts of reservoir and value management. The integrated reservoir management concept is based on integration of technology (seismic, geologic, geostatistics, drilling, environmental ect.), people (management, geoscientists, engineers), tools (from seismic to computer hardware and software) and data (geological, geophysical, financial). Risk and uncertainty' management is strong related with value-based management and value creation for shareholders. In article author tries to assign each level of risk estimation stage of investment project realization as well as tools of analysis, which are allowing quantifying level of risk and uncertainty.
Procesy restrukturyzacyjne w polskim górnictwie węgla kamiennego w aspekcie zrealizowanych przemian i zmiany bazy zasobowej
(Wydawnictwa AGH, 2010) Paszcza, Henryk
The article presents selected issues of hard coal sector restructuring process in the last twenty years, particularly the processes of organizational changes, activities aimed at excessive production capacity and overfull employment reduction. Individual governmental programmes have been presented in details and the analysis of effectiveness of their implementation in mining sector has been conducted. The comparison of functioning of the sector to the assumptions of these programmes has been done. The evaluation of compliance of realized activities with the directions of governmental programmes has been done in conclusions as well as the basic technical and economic indexes of mining activity in the previous decades have been presented.
Gospodarka zasobami złóż węgla kamiennego
(Wydawnictwa AGH, 2010) Kulczycki, Zdzisław; Sowa, Artur
It the paper, on background of changing of law regulation, the authors showed the general principles of development of resources of hard coal in period 1989-2009. They indicated the part of state mining authority in process extraction of deposits of hard coal. It the analysis of maintaining of the records of the economically viable geological resources and industrial resources were showed as resulting of mining activity. The authors presented changes of economically viable geological resources and industrial resources from actualizing deposits development plan by entrepreneurs.
