The paper presents an author’s method of eco-efficiency assessment of mining production processes in hard coal mines, which enables integrating results of evaluating both environmental and economic aspects. The proposed method uses life cycle approach to assess environmental efficiency and the result of operating activities to assess economic efficiency. The comprehensive method of assessing mining production processes was proposed as the Key Performance Indicator (KPI) in hard coal mines in Poland to be used to support decision making in mining companies.
The actual situation of hard coal mining in Poland has been presented. In particular, these factors, which have impact on the competiveness of mining sector were highlighted and need of its improving has been stressed. Outlining present situation of hard coal mining an attention was paid to its specific threats. The primary analytical material is based on the results of questionnaire conducted among 92 specialists and experts from the mining sector. The questions were related to chances and threats for development of hard coal mining in Poland. The factors determining them were grouped in such domains as economy, technology, geology, social and law aspects. Moreover, the special attention was paid to the problem of increasing and high costs of coal production which constitute significant threat for the financial and economic situation of the mining enterprises. Also the adverse influence of these high cost on the competitiveness of Polish hard coal with other world producers and with other energy carriers was emphasized. The conclusions summarize the achieved results of analysis.Keywords: hard coal mining sector, factors determining chances for development, factors determining threats for development, cost of coal mining.Górnictwo węgla kamiennego jest strategicznym sektorem polskiej gospodarki, z uwagi na wysoki, blisko 90%, udział paliwa węglowego w wytwarzaniu energii elektrycznej, z czego około 60% stanowi węgiel kamienny. Różnego rodzaju prognozy długoterminowe wskazują, że pomimo zmian w strukturze polskiego miksu energetycznego węgiel kamienny nadal pozostanie ważnym nośnikiem energii. Tym niemniej istotnym problemem jest to aby był nim nadal węgiel wydobywany w polskich kopalniach. Stąd, analiza szans i zagrożeń dla rozwoju górnictwa węgla kamiennego w Polsce jest niezwykle ważna, a jej wyniki mogą stanowić podstawę racjonalnych planów i działań zapewniających konkurencyjność cenową tego paliwa w wymiarze globalnym. Ponadto, należy mieć na uwadze fakt, że górnictwo węgla kamiennego jest jednym z największych pracodawców w Polsce, ocenianym na blisko 500 tysięcy miejsc pracy, zarówno tych bezpośrednich w kopalniach jak i otoczeniu tego górnictwa. Niestety negatywnym zjawiskiem, które stwarza istotne zagrożenie dla rozwoju polskiego górnictwa węgla kamiennego są Dla rozpoznania przedmiotowego problemu szans i zagrożeń w polskim górnictwie węgla kamiennego została zastosowana metodyka badań eksperckich, polegająca na pozyskaniu, a następnie specjalistycznej analizie opinii, odpowiednio licznego zbioru danych, uzyskanego od 92 respondentów uznanych jako ekspertów. Dane te zostały zawarte w specjalnie opracowanym kwestionariuszu, który składał się z trzech części: A -dotyczącej szans rozwojowych górnictwa, B -dotyczącej zagrożeń dla tego przemysłu i C -dotyczącej diagnozy stanowiącej podsumowanie sytuacji w analizowanych obszarach. W metodologii analizy wyników została zastosowana jednolita skala ilościowej oceny stopnia ważności wyróżnionych czynników, od 5 -bardzo ważny, do 1 -trudno powiedzieć.Na wstępie p...
Coal mine closure processes are being carried out in the European Union due to the current energy transition. The use of coal-fired power plants has been significantly reduced in recent years. Because of the significant financial outlays, processes of rationalization and minimization of the mine liquidation cost should be carried out. In this paper, a statistical analysis of the liquidation processes in hard coal mines in Poland was carried out. A new tool was developed in order to optimize the mine liquidation costs. The mine liquidation process can be divided into ten different processes, which have been analyzed in detail in this research work. The method of the assessment of the amount of estimated liquidation costs described is based on the analysis of the total liquidation cost. The presented method of signaling deviations of the costs of the liquidation of the mining plant from the average value is a useful tool in the process approach to the issues connected with the restructuring of post-industrial property. The presented cost assessment procedure may facilitate the monitoring of conducted activities in terms of rationalization and minimization of the costs incurred. Finally, the proposed method for assessing the cost of mine liquidation is understandable, simple, and easy to use for applications in preliminary design works and on-going engineering works.
