The purpose of the study is to investigate and characterize the hydrogeological conditions at the Alpu Sector-A Coal Field which is located in the Eskisehir Province in Turkey. This is required to provide baseline hydrogeological information before environmental impact assessment of the planned mining operations can be done. The characterization studies included hydrogeological and hydrochemical analysis of groundwater and surface water. The spatial and temporal variations in groundwater levels are determined by measuring the groundwater levels in drilled observation and pumping wells and analyzing the pore pressure from the vibrating wire piezometers installed in different depths. The hydraulic parameters of the groundwater system are estimated by conducting aquifer tests in drilled pumping wells. The hydrochemical characteristics of the waters are based upon measured field water quality parameters and chemical analyses of the samples taken at periodic intervals from both surface and groundwater. The most prolific aquifer in the Sector-A is the alluvium aquifer which interacts with the Porsuk Stream. There is a vertical upward hydraulic gradient with excessive pore pressure beneath the coal seams. None of the waters in the study area are suitable for drinking and irrigation purposes.

Fırat, Egemen; Yazıcıgil, Hasan; Department of Geological Engineering (2013)
The purpose of this study is to characterize the hydrogeological conditions at the northern part of the Kışladağ Gold Mine located in Uşak Province in the West of Turkey. Because of the planned mining activities in the area, it is essential to characterize the system in order to assess the impacts of mining operations on surface and groundwater systems. The characterization studies included the hydrological, hydrogeological, and hydrochemical analysis of surface and groundwater. Hereby, the relevant measure...
Stability analyses of the dump site culvert in Tınaz surface mine
Özcan, Ömer Can; Ünal, Erdal; Department of Mining Engineering (2003)
In this thesis, studies associated with the stability analyses of the box-shaped dump-site culvert constructed in Tınaz Surface Mine of Turkish Coal Enterprises (TKİ) are presented. In addition, stability conditions of other culvert alternatives are evaluated. Existence of creeks in a surface mining area is a significant factor to be considered in selection of dump-site location. Since, the dumped overburden material on the valley acts as a barrier and behaves like a dam causing flood problem behind the dum...
Hydrogeochemical investigation of groundwater characteristics in Alpu coal field, Eskisehir-Turkey
Tural, Ceren Yazıgülü; Çamur, Mehmet Zeki; Department of Geological Engineering (2021-6)
Hydrogeochemical characteristics and quality of groundwater resources in Alpu Coal field to the north of Porsuk Creek are investigated. EC, pH, DO and ORP average value ranges are determined as 438-1227 μS/cm, 7.43-8.69, 3.29-6.05 mg/l and 106-180 mv, respectively in spring waters and as 452-30233 μS/cm, 7.46-8.48, 0.6-6.0 mg/l ve 198- -183 mv, respectively in well waters. All spring waters are in HCO3 - Mg, Mix(Ca-Mg), Ca facies. Groundwater facies, stratigraphically downward: change in the order of HCO3, ...
