Abstract (English):	This study addresses the critical issue of technogenic safety and revitalization of devastated landscapes in the Kryvyi Rih basin, a major mining region in Ukraine. It highlights the environmental challenges posed by extensive mining activities, including sinkhole formation, soil degradation, and biodiversity loss, exacerbated by climate change and erosion. The research evaluates the effectiveness of vegetation cover through phytomelioration efficiency coefficients (Kfm), revealing a steady decline from 1984 to 2024 due to expanding devastated areas. For instance, Kfm values dropped from 3.6 to 2.8 for sinkhole No. 1, indicating reduced ecological resilience. A key focus is the proposed cemented paste backfilling technology, utilizing mining waste to fill sinkholes. This method aims to mitigate surface deformations, enhance public safety, and restore soil integrity while repurposing industrial byproducts. The study analyzes sinkhole dynamics using GIS and historical data, identifying nonlinear growth patterns, particularly during 1995-2005. Polynomial models (R² up to 0.997) effectively describe these trends. Economic analysis underscores the escalating costs of delayed revitalization, with expenses rising up to sevenfold over 38 years. The research advocates for timely intervention to reduce both environmental risks and financial burdens. In conclusion, the integration of backfilling technologies and phytomelioration strategies offers a sustainable solution for restoring Kryvyi Rih's landscapes, aligning with global climate goals and regional development needs. The findings emphasize the urgency of implementing these measures to ensure ecological stability and long-term socio-economic benefits. [ABSTRACT FROM AUTHOR]
Abstract (Croatian):	Studija istražuje kritična pitanja tehnogene sigurnosti i obnove devastiranih krajolika u bazenu Krivoga Roga, jednom od najvažnijih rudarskih područja Ukrajine. Istraživanje naglašava ekološke izazove uzrokovane intenzivnom rudarskom aktivnošću, uključujući stvaranje vrtača, degradaciju tla i gubitak bioraznolikosti, što je dodatno pogoršano klimatskim promjenama i erozijom. Analizom koeficijenata fitomelioracijske učinkovitosti (Kfm) studija procjenjuje učinkovitost vegetacijskoga pokrova, otkrivajući stalan pad od 1984. do 2024. zbog širenja devastiranih područja. Primjerice, vrijednosti Kfm za vrtaču br. 1 pale su s 3,6 na 2,8, a to upućuje na smanjenu ekološku otpornost. Ključni fokus istraživanja jest tehnologija ispunjavanja s cementiranom pastom, koja se koristi rudarskim otpadom za popunjavanje vrtača. Cilj je ove metode smanjiti devastirane površine, poboljšati javnu sigurnost i obnoviti strukturu tla, istovremeno reciklirajući industrijske nusproizvode. Korištenjem GIS-a i povijesnih podataka studija analizira dinamiku vrtača, identificirajući nelinearne obrasce povećanja, posebno u razdoblju od 1995. do 2005. Polinomski modeli (s R² do 0,997) učinkovito opisuju ove trendove. Ekonomska analiza ističe rastuće troškove odgađane revitalizacije, s povećanjem troškova do sedam puta tijekom 38 godina. Zaključeno je kako kombinacija tehnologije ispunjavanja i strategije fitomelioracije nudi održivo rješenje za obnovu krajolika Krivoga Roga usklađujući se s globalnim klimatskim ciljevima i regionalnim razvojnim potrebama. Rezultati ističu hitnu potrebu za provedbom predloženih mjera kako bi se osigurala ekološka stabilnost i dugoročne socioekonomske koristi. [ABSTRACT FROM AUTHOR]
