Purpose: Growing global warming increases the threat of energy supply security in the form of the “blackout” phenomenon. Pumping stations pump out approximately 100 million m3 of water annually (data from 2023). Discontinuation of mine water pumping would expose neighbouring mines and lower-lying areas to flooding. Design/methodology/approach: For the designed database of functional scenarios of the mine water pumping station, the optimal variant was selected based on economic and ecological criteria as well as the energy security criterion. Findings: The research analyzed five technically feasible variants of modernization of mine water pumping stations. Each variant is characterized by a different degree of security of energy supply and a different level of meeting energy demand. Research limitations/implications: All variants of modernization of the pumping station provide for the production of electricity for own needs. All investment attractiveness factors should be taken into account while making investment decisions. It is up to the decision-maker to make the final multi-criteria decision so as to implement the selected variant. Practical implications: One of the challenge is to ensure security of energy supplies in the event of a sudden energy shortage. Pumping stations have some retention, nevertheless a longer shutdown time could lead to environmental problems. Removing the damage would definitely require large financial expenditures and would take several years. Social implications: The planned project of the energy supply security can have a positive impact on the local community and economy. The projects discussed will create new markets related to "green energy". Originality/value: The aim of the article is to assess the investment relevance of safety projects for power supply to mine water pumping stations. The combination of the problems of drainage of liquidated mines, the use of renewable energy sources and energy storage to improve the security of power supply to pumping stations has not been the subject of scientific research so far.

Zmiany klimatyczne, nadmierna emisja gazów cieplarnianych oraz pogarszająca się jakość zasobów wodnych, wymusza działania łagodzące skutki działalności przemysłowej. W artykule przedstawiono przykład możliwości planowania zmian techniczno-organizacyjnych rutynowych działań Spółki Restrukturyzacji Kopalń S.A., związanych z odpompowywaniem wód dołowych w taki sposób, by zarówno ograniczyć wykorzystanie energii ze źródeł kopalnych, zminimalizować emisję CO2, jaki i przyczynić się do ograniczenia zużycia wody ze źródeł konwencjonalnych. Wyniki badań dowiodły, że dostępne projekty w zakresie samowystarczalności energetycznej SRK S.A. charakteryzuje zróżnicowana atrakcyjność inwestycyjną w zależności od przyjętego kryterium oceny, lecz za najbardziej pożądane należy uznać te projekty, w których balans pomiędzy nakładami inwestycyjnymi, a prognozowanym zabezpieczeniem zaopatrzenia w wodę, potrzebami energetycznymi i oczekiwaniami społecznymi jest najkorzystniejszy.

Climate change, excessive emission of greenhouse gases and deterioration of the quality of water resources require measures to mitigate the effects of industrial activity. The article presents an example of the possi bility of planning technical and organizational changes in the routine activities of Spółka Restrukturacji Kopalń S.A. related to the pumping of mine water in such a way as to limit the use of energy from fossil sources, minimize carbon dioxide emissions and contribute to the reduction of water consumption from conventional sources. The results of the research have shown that the available projects in the ﬁeld of energy self-sufﬁciency of SRK S.A. are characterized by a variety of different investment attractiveness, depending on the applied evaluation criterion. Nevertheless, the most desirable projects should be those in which the balance between the investment costs and the forecasted security of water supply, energy needs and social expectations is the most favorable.

The purpose of this study is to outline the current problems with the company's documentation workflow process and propose a plan to implement a new automated system to eliminate waste and improve the company's cash flow. Every enterprise is required to accurately record business operations. Accounting is the foundation of an organization, serving not only to meet legal requirements, but also to support management processes. In the case of large enterprises, complex accounting carries the risk of problems with timely and correct accounting, which can lead to delays in payments, reminders, collection procedures and interruptions in deliveries. As a result, it becomes crucial to put processes in place to safeguard liquidity. The study includes an analysis of the company's current documentation workflow process and identification of problems associated with it. A plan is then proposed to implement a new automated system to eliminate waste. The methodology is based on an analysis of the company's internal data and available technological solutions. The main results of the study include the identification of existing problems in the documentation workflow process and a plan for implementing a new system. The findings indicate that improving process efficiency can help increase the company's cash flow. The study introduces a new perspective on records management in enterprises, especially in the context of eliminating waste and improving liquidity. The theoretical value of the work lies in identifying opportunities for effective records management in the context of supporting business processes. The introduction of an automated documentation workflow system can bring practical benefits, such as reducing payment delays, avoiding debt collection procedures and improving the overall efficiency of business operations.
