In connection with the implementation of the international project TEXMIN within the framework of the RFCS fund, a project for the liquidation of the Głowacki Shaft in Rybnik (Poland) was undertaken, which takes into account the effects of climate change, i.e. evaluation of the increase of precipitation in the region. In addition to the standard research undertaken before liquidation activities, precipitation data recorded by the Institute of Meteorology and Water Management from 1995 to 2019 was collected and the precipitation variability was analysed. As a result, a method for liquidation of the shaft was selected consisting of constructing a permeable backfill column in the shaft and using a shaft pipe filled with permeable backfill material. Metallurgical aggregate was identified as a suitable backfill material, for which degradation tests, filtration coefficient tests and an assessment of its impact on water quality were carried out. It has been determined that a backfill column constructed in this manner can fulfil its function as a long-term gravity-driven water flow.

It is widely known and accepted that the global climate is changing with unprecedented speed. Climate models project increasing temperatures and changes in precipitation regimes which will alter the frequency, magnitude, and geographic distribution of climate-related hazards including flood, drought and heat waves. In the mining industry, climate change impacts are an area of research around the world, mostly in relation to the mining industry in Australia and Canada, where mining policies and mitigation actions based on the results of this research were adopted and applied. In Poland, there is still a lack of research on how climate change, and especially extreme weather events, impacts mining activity. This impact may be of particular importance in Poland, where the mining industry is in the process of intensive transition. The paper presents an overview of hazardous events in mining in Poland that were related to extreme weather phenomena. The needs and recommended actions in the scope of mitigating the impact of future climate change on mining in all stages of its functioning were also indicated. The presented analyses and conclusions are the results of the first activities in the TEXMIN project: The impact of extreme weather events on mining activities, identifying the most important factors resulting from climate change impact on mining.

W ostatnim czasie nastąpiły w Polsce zasadnicze zmiany w zakresie legislacyjnym, które przyniosło ze sobą wejście w życie przepisów ustawy Prawo wodne z 20 lipca 2017 r. Jednym z wymagań dotyczących ochrony ujęć wód jest obowiązek przeprowadzenia analizy ryzyka. Co powinna ona zawierać? Jakie nowe obowiązki spoczywają na podmiotach realizujących zbiorowe zaopatrzenie w wodę?
