“…A literature search revealed the phrase 'mineral security' in just 10 publications, compared with 46,535 for food security (Web of Science; 25 May 2022), with few prior definitions of the term. In all prior uses, and like the term 'critical minerals', mineral security has been used in the context of a state's quest to secure critical supplies for defence and industry [38][39][40] . A literature search for the phrase 'mineral poverty' revealed no results (Web of Science; 25 May 2022).…”

“…Mining is the cornerstone of global economic growth [1], and the extraction of mineral resources provides important raw materials for the economic development of countries [2,3]. However, by the nonstop ore mining, the sum of generated underground voids increases, posing a serious risk to the environment [4,5].…”

In undercut-and-fill mining, backfills show weak tensile strength and poor ductility properties since they act as artificial pillars to support stope roofs. Hence, the enhancement of the stability of mining structures and backfills is a crucial requisite for underground mining backfill operations. This study addresses the reinforcing effect of polypropylene (PP) on the strength features of combined cement-based tailing backfill (CCTB) with varied cement/tail ratios (c/t: 1:8 to 1:4) at both macroscopic and microscopic levels. Fill specimens containing a fixed solid content of 70 wt% were reinforced with fiber (0.6 wt%) and with no fiber (classified as a reference sample). They were then cast in mold sizes of 160 × 40 × 40 mm3, and cured for 7 days. Following curing, some experiments covering three-point bending assisted by DIC and SEM were performed to inspect the microstructure and strength features of CCTB. The results illustrate that the flexural strength of fiber-oriented CCTB increases along with the c/t fraction, but it is not greater than that of specimens with a high c/t fraction without fiber. Adding PP fiber, the peak deflection of CCTB specimens was improved, and the increment of peak deflection increased linearly with rising c/t fraction, enhancing CCTB’s bending characteristics. CCTB damage starts from the bottom to the middle, and the main cause of the damage is the stress distribution at the lowest section. The addition of fiber to CCTBs increases the ability to dissipate energy, which helps to hinder crack extension and prevent brittle damage from occurring. The microstructure shows that AFt and CSH were key hydrate materials in CCTB. As a result, this study develops the security of mining with backfill and helps to determine its design properties for safe production inputs and sustainable filling operations.

“…In the USCB, all technological types of hard coal occur, including coking coal, which, since 2014, has been included in the European list of critical raw materials [1][2][3]. The total prognostic resources of hard coal in the USCB amounted to 4616.17 Mt and 20,926.58 Mt of prospective resources.…”

“…Energy coals represent almost three-fourths of the resources (70.96%) and coke coals are above one-fourth (27.83%), whereas other types of coals remain negligible. [1]. The USCB has also a high potential for coal-bed methane (CBM) [3][4][5][6][7][8].…”

“…Therefore, the main goals of this study were (1) to analyze the major and trace elements' concentrations in the sedimentary rocks of the coal-bearing succession of the USCB, (2) to demonstrate the distribution and stratigraphical variability of the selected elements, (3) to discuss quartz origin, sediment provenance, and source-area rock compositions, and (4) to establish if chemostratigraphy tools could be successfully applied to analyze the coalbearing series of the USCB.…”

The Upper Silesian Coal Basin (USCB), located in southern Poland, is the major coal basin in Poland, and all technological types of hard coal, including coking coal, are exploited. It is also an area of high potential for coal-bed methane (CBM). Despite the increasing availability of alternative energy sources globally, it is a fact that the use of fossil fuels will remain necessary for the next few decades. Therefore, research on coal-bearing formations using modern research methods is still very important. The application of geochemistry and chemostratigraphy in reservoir characterization has become increasingly common in recent years. This paper presents the possibility of applying chemostratigraphic techniques to the study of the Carboniferous coal-bearing succession of the Upper Silesian Coal Basin. The material studied comes from 121 core samples (depth 481–1298 m), representing the Mudstone Series (Westphalian A, B). Major oxide concentrations of Al2O3, SiO2, Fe2O3, P2O5, K2O, MgO, CaO, Na2O, K2O, MnO, TiO2, and Cr2O3 were obtained using X-ray fluorescence (XRF) spectrometry. Trace elements were analyzed using inductively coupled plasma mass spectrometry (ICP/MS). The geochemical record from the Mudstone Series shows changes in the concentration of major elements and selected trace elements, leading to the identification of four chemostratigraphic units. These units differ primarily in the content of Fe, Ca, Mg, Mn, and P as well as the concentration of Zr, Hf, Nb, Ta, and Ti. The study also discusses quartz origin (based on SiO2 and TiO2), sediment provenance and source-area rock compositions (based on Al2O3/ TiO2, TiO2/Zr, and La/Th), and paleoredox conditions (based on V/Cr, Ni/Co, U/Th, (Cu+Mo)/Zn, and Sr/Ba) for the chemostratigraphic units. Chemostratigraphy was used for the first time in the study of the Carboniferous coal-bearing series of the USCB, concluding that it can be used as an effective stratigraphic tool and provide new information on the possibility of correlating barren sequences of the coal-bearing succession.
