Abstract: Old graves site of MSW (municipal solid waste) remain active as environmental source of pollution. The purpose of our research is the desire to study and improve an ecological aspect including the topic of surface and groundwater. Currently, the main waste disposal site for the Voronezh millionth city is a landfill located on the right bank of the Don near the rural area of the Devitsa in the Semilukskiy district of Voronezh region. This landfill of MSW began to be used in 2012. It is located closer to former used landfill closed in the same year. The former and now existing landfills were created on the site of previously worked quarries for the extraction of clay and sand for the construction industry. The landfill for receiving solid household waste (MSW – there was such a name in these years) was started to be used after excluding the significant comments of the place of former used Sredniy quarry mine in 1993. Waste collection began to work in 11.11.1993. The landfill accepted waste for disposal until 16.03.2012. Moreover, the situation with the storage of waste was considered as an emergency over the past few years. Since, according to the project, the landfill was overfilled by 30%! The main purpose of this article is to assess the intake of pollutants into groundwater from a closed landfill at the Sredniy mine in the Semiluksky district of the Voronezh Region and to determine their release into the Don River through the aquifer. The report of the monitoring activities of LLC Voronezhgeologiya will be used in the context of research. As a result, solutions of reducing the pollution impact on this area will be identified.

Abstract: The composite strata of coal floor is an important barrier to block the lifting and bursting of thick limestone groundwater into the mining space. Taking J3 and J4 mining areas of Handicapping Coalfield as the object, this paper selected the thickness ratio of plastic brittle rock core recovery rate, composite comprehensive strength, Equivalent water barrier coefficient, Effective water-resistant layer thickness and fault complexity as the main control factors, and determined the comprehensive weight of index factors based on the entropy weight theory. Using the Archaist vulnerability index grading evaluation model, the water-isolation ability of the composite strata in the floor of J16-17 coal seam is quantitatively evaluated and divided into five grades: extremely weak, weak, medium, strong and extremely strong. The results show that the areas with strong and extremely strong water-isolation ability of the composite strata of coal floor account for 38.67% of the total area, the areas with moderate and extremely weak water-isolation ability account for 51.45%, and the areas with weak and extremely weak water-isolation ability account for 9.88%. In this paper, the coupling effect of multiple factors on composite strata is considered, and the quantitative classification and zoning discrimination of water-isolation ability of composite strata is realized, which provides technical support for accurate evaluation of water-inrush risk of coal floor.

Abstract: Aeromagnetic data and Landsat image, were assessed to establish a relationship between morphostructural feature and borehole yield of a sub-basin of Osun basin in the Northern part of Ilesha, southwestern Nigeria. Four morphostructural factors (Geomorphological unit, Slope, regional structure, and lineament) were considered. Geomorphological units were classified based on digital elevation model (DEM), Lineaments were identified and extracted using edge detection technique, slope were generated from the digital data derived from Landsat imagery, and the regional structure were extracted using magnetic data filtering and enhancement techniques processes. The results of morphostructural features shows five (5) various geomorphic units; (Denudation hill, linear ridge, pediment inselberg complex, pediment and moderately weathered Pediplain) and four (4) main structural trends (NE-SW, NW-SE, ENE-WSW and E-W directions). The relationship between the morphostructural factors and borehole yield were assessed using spatial global autocorrelation and spearman rank correlation. Moran’s I global tests for dependence shows that geomorphological units, and regional structures were clustered given the z-scores of 2.46 and 1.99, p-values of 0.01 and 0.04, Moran’s I index value of 0.08 and 0.06 respectively. Likewise, borehole yield, lineament and slope were dispersed given the z-scores of 0.89, -0.43 and -1.15, p-values of 0.38, 0.66 and 0.25, Moran’s I index value of -0.06, -0.04 and -0.07 respectively. The Spearman’s rank correlation for the four independent variables (Geomorphological unit, Slope, Fracture, and Lineament) are statistically significant to the observed borehole yield, with correlation coefficients of -0.332, 0.137, -0.031, 0.200 respectively. The study concluded that slope and lineament are capable of favoring high borehole yield indicative of active surface recharge mechanism that is prominent in Schist belts and regional structures have little or no contribution to borehole yield in schist belts due to the influence of developed clayey filling resulting from the deep weathering processes.
