“…Packed technique was used in order to determine the equilibrium data. After defining optimum reaction conditions (pH, resin dosage, contact time), experimental results were applied to the wastewaters [34][35][36]. It is thought that results of this study can be useful for treat ment processes of sectors containing heavy metal in their wastewaters.…”

Spatiotemporal subsidence over Pabdana coal mine Kerman Province, central Iran using time-series of Sentinel-1 remote sensing imagery

Environmental monitoring of mining regions using satellite imagery is crucial for sustainable exploitation and preventing geohazards. Movements due to the failure of the roof in underground coal mining, by migrating upwards and outwards from the seam being mined, could eventually appear as ground deformation. To investigate the matter further, the surface deformation that occurred over the Pabdana mining area was monitored in three time periods, between October 2, 2014, and July 27, 2019. Persistent scatterer interferometry (PSI) was used based on 150 ascending and descending Sentinel-1A images. The maximum mining subsidence rate during the studied periods was about 30 to 35 mm/yr. The PSI analysis shows that the subsidence rate varied both temporally and spatially during the three studied periods. The time series and the displacement rate for various cross-sections highlight a clear quantitative relationship between coal extraction progress and subsidence, which proceeded southward throughout the three study periods. So, considering coal mining subsidence as a geohazard, land developments and structures over the mining area may be safeguarded. The approach used in this investigation can be implemented in other similar coal mining zones.

“…Although the mineralogy, inorganic geochemistry, and stratigraphy of the Mesozoic coals of Iran have been investigated by several authors (e.g. Pazand 2015;Goodarzi et al 2006;Ghassabiyan et al 2010; Moore and Esmaeili 2012;Ardebili et al 2012;Moosavirad et al 2013;Ghavidel-Syooki et al 2015;Rajabzadeh et al 2016), only little information is available on the characteristics of organic material that formed these coals (Solaymani and Taghipour 2012;Stasiuk et al 2006;Alizadeh et al 2011Alizadeh et al , 2015Ghavidel-Syooki et al 2015). In order to investigate depositional conditions, plant input and thermal maturity of the aforementioned Iranian coal deposits, a wide range of organic petrological and organic geochemical methods was applied.…”

Jurassic and Triassic coals and organic matter-rich shales of the Tabas Basin, Iran, were investigated with respect to their thermal maturation and petrographic composition. The Triassic coals of the Parvadeh coal field range in vitrinite reflectance between 1.17% and 1.37% and the Jurassic coals of the Mazino coal field between 2.08% and 2.29% VR r . Maceral analysis revealed a predominance of vitrinite in all samples, with slightly higher percentages of inertinite in the Jurassic samples. Rock-Eval analyses confirm the presence of type III kerogen in the Triassic coals, while the Jurassic coals contain strongly carbonized residual kerogen. The range of sulfur contents for coals from the Parvadeh coal field (0.37% to 4.64%) and Mazino coal field (0.45% to 2.92%) is related to the effect of marine water in peat. The studied samples are characterized by the predominance of short-over long-chained n-alkanes. The relatively high Pr/Ph ratios indicate predominance of terrestrial organic matter whereas Pr/n-C 17 and Ph/n-C 18 ratios prove oxic conditions during deposition. In addition, the DBT/Phen ratio shows that these coals formed in fluvial/deltaic environments. Molecular geochemical parameters such as carbon preference index (CPI, 0.99-1.04), methyl phenanthrene index (MPI, 1.20-1.60), methyl naphthalene ratio (MNR, 1.61-3.45), and ethyl naphthalene ratio (ENR, 4-6.78) confirm the high maturity of the samples. Burial and thermal history reconstruction indicates necessity of an erosional thickness of about 4000 m in the Parvadeh area. Towards the Mazino area, a higher basal heat flow up to 80 mW m -2 is assumed for the Paleogene leading to higher maturities.
