Oddawany do rąk Czytelników rocznik „Gospodarka surowcami mineralnymi w Polsce w latach 2012–2021” jest drugą edycją tego wydawnictwa, przygotowaną przez Pracownię Polityki Surowcowej Instytutu Gospodarki Surowcami Mineralnymi i Energią PAN w Krakowie. Rocznik ten prezentuje podstawowe dane statystyczne w zakresie gospodarowania surowcami mineralny...

This work is an attempt to determine the scale of threats to the mineral security of Poland in the area of non-energy raw materials resulting from Russia’s invasion of Ukraine. In particular, it aims to identify those industries whose proper functioning may be threatened in the face of the limited supply of raw materials from three directions – Rus...

W latach 1993-2015 zespół Pracowni Polityki Surowcowej Instytutu Gospodarki Surowcami Mineralnymi i Energią PAN przygotowywał i wydawał rocznik pt. „Bilans gospodarki surowcami mineralnymi Polski i świata”, natomiast w latach 1997–2015 – także anglojęzyczny „Minerals Yearbook of Poland”. Działania te były możliwe dzięki finansowaniu przez ministers...

The sandstones with a laminated structure are common building materials. Lamination is macroscopically expressed as colour and grain size variations observed both in the deposit and within individual beds; therefore, the properties of such sandstones are diverse depending on the spatial distribution of the binding mass and framework components. For...

The Istebna sandstones are one of the main stone materials used for centuries in the construction industry in Kraków and the surrounding area. It was supported not only by their decorative properties and technical parameters, but also the proximity of the outcrops. The results of research on changes in the physical and mechanical properties of samp...

A lithological profile and measurements of the orientation and spacings of natural discontinuity planes were carried out in the Górka-Mucharz sandstone excavation (Krosno Beds, Outer Carpathians, Poland). In addition, the density of the discontinuities was assessed by measuring their spacings using oriented digital photographs of the quarry walls....

The subject of the research was the Middle Miocene red algal limestone from the Włochy deposit, which is currently the only place of exploitation of the Pińczów Limestone representing a local type of the Leitha Limestone. The collected samples of this rock belong to the organodetric facies of diverse grain size and sorting of clastic material. Cons...

The work concerned the effects of the thermal treatment of diatomites from the Jawornik deposit (an example of the diatomites of the Leszczawka Member of the Polish Outer Carpathians). Five distinct lithological varieties were subjected to calcination at 600°C in ambient air.The thermal impact induced the following changes to the rocks. Their overa...

Grain-size analyses were carried out on three samples representing parallel laminated, convoluted and massive sandstones. Thin sections were cut perpendicular and parallel to the bedding of the rocks. Applying a digital camera coupled to a polarizing microscope and an image analysis software, the type of the detrital material was identified and the...

Sandstones of different genesis and development were studied with the aim of establishing an impact of directional microstructures on rock properties. The investigations included petrographical observations and physico-mechanical determinations. The microstructures were manifested in the presence of elongated grains arranged along preferred directi...

Grain-size analyses were carried out on three samples representing parallel laminated, convoluted and massive sandstones.

The paper is an attempt to evaluate the geological and quarrying conditions of the Blessed Salomea "marble". Its physico-mechanical properties were determined in relation to the lithology. The probable volume of excavated rock material was compared to the volume of the small architecture elements, mainly altars and tombstones made of this stone. Th...

Diatomites belonging to a list of raw materials used in the EU criticality assessment are essential to many industrial applications due to a unique combination of their physical properties, i.e. porous and permeable structure, high specific surface area and adsorption capacity, low density and thermal conductivity, and chemical inertness. The pres...

The complex pore space considerably affects the unique properties of diatomite and its significant potential for many industrial applications. The pore network in the diatomite from the Lower Miocene strata of the Skole nappe (the Jawornik deposit, SE Poland) has been investigated using a fractal approach. The fractal dimension of the pore-space vo...

One of the fundamental characteristics of diatomites is their structural porosity as it controls specific properties of these rocks and their possible industrial applications. The authors examined the interaction between natural diatomites (not calcinated) from Polish Carpathian Flysch Belt and a brine composed of the mixture of NaCl, KCl and MgCl2...

Streszczenie Przedstawiono stan kopalń na tle tradycji wydobycia i użytkowania surowców kamiennych. Wytypowano czynne kamieniołomy, w których tradycyjnie pozyskiwane były bloki, jak też i takie, w których z racji wykształcenia serii złożowych, bloki mogą być przedmiotem eksploatacji w przyszłości. Oceniono też złoża, w których niegdyś wydobywano ma...

This article presents the history of mining for rock raw materials in the Cieszyn area since the beginning of the 20th century. The study assessed the possibility of continuing these activities in relation to the ongoing enlargement of conservation areas. The conflict between mining these deposits and environmental interests was described. The resu...

The paper presents results of investigations on the influence of joint and micro-fractures on the shape of a crushed grain - one of the most important parameter of the quality of crushed aggregate. Three structural types of the Jurassic limestone exploited in the Nielepice deposit nearby Kraków (Poland) were analysed. Cuboidal samples of platy and...
