Determining the source of groundwater infiltrating mine pits is one of the most interesting challenge for mining engineers and designers. The uncontrolled groundwater flow will delay the planned schedule and have a negative impact on extraction costs and mining operations. Determining the groundwater source by hydrochemical and isotopical interpretations in the Goharzamin iron mine, located in south-central Iran, plays a significant role in comprehending hydrochemical and hydrogeological processes and designing an effective dewatering system in this mining area. Through three phases of groundwater sample collection from seepages and boreholes, a total of 75 samples were gathered for analysis, including 12 samples containing heavy metals and stable isotopic data (D and 18O), 5 samples containing 14C and 13C, and another 5 samples containing 3H data. Results indicated that all samples belonged to saline and brackish water categories (EC > 4 mS cm− 1), with a predominant sequence of Cl−-SO42−-HCO3−-NO3−, and Na+-Ca2+-Mg2+-K+ for anions and cations, respectively. Conservative tracers (Cl, Br, and B) and stable isotopes demonstrated that Kheirabad Salt Lake (located approximately 13 km north of the mine) is unlikely to be the source of groundwater. Radiocarbon and tritium age dating suggested that the majority of groundwater in the mining area was infiltrated during the Holocene and late Pleistocene epochs (paleowater) rather than being replenished by recent rainfall. Hydrochemical variations observed in samples collected during the wet season are generally attributed to the mixing of surface water and groundwater at fractures around the mine pit.

Hydrogeochemical environment is of critical importance for the environment-friendly operation of underground oil storage caverns. The construction of underground oil storage caverns usually has an impact on the hydro-environment. The characterization and analysis of the hydrogeochemical environment can provide information on the relation between construction and hydro-environment. The quality of water samples was detected and analyzed to determine the chemical type in an underground oil storage cavern in China. The water samples are classi ed using principal component analysis and cluster analysis. The source and proportion of seepage water into the storage caverns are determined with end member mixing calculation. The results show that the chemical type of groundwater is mainly HCO 3 + Cl − Na type, and the two dominant factors affecting the evolution of hydrogeochemical content are rock dissolution and groundwater seepage. All water samples can be catalogued as seepage water, water curtain water, X River water and background water. The water curtain water can fully penetrate into the ground to provide containment for the storage caverns, and the water curtain system has a good performance and can basically cover the project area. Most of the seepage water into the storage caverns comes from water curtain water and X River water, while the proportion of background water is relatively low. The construction of underground oil storage caverns affects the groundwater ow regime by changing the directions of groundwater ow around the caverns. This study showcases the use of hydrogeochemical analysis in depicting the interplay between surface water and groundwater for underground rock engineering.

“…Although many practical technical problems have been solved in a large number of cases in recent years, there are still a large number of outstanding technical and theoretical problems to be solved. Some researchers have carried out the research on the main geological problems faced by the water conveyance tunnel and the tunnel size setting, and summarized the situations such as rock burst, deformation of surrounding rock, water inrush, fault zone, toxic gas and high ground temperature that are often encountered in tunnel construction [4][5][6] . At the same time, the tunnel's diameter, length, and depth must also be thoughtfully planned while taking into account the route's complicated and shifting geological circumstances 7 .…”

The construction practice of water conveyance tunnels often encounters various complex geotechnical engineering conditions, which bring huge challenges to the design and construction of water conveyance tunnels. Based on the theory of rock elastic–plastic mechanics and finite element analysis technology, this article carried out investigations of engineering geological features, geological formations and hydrological conditions establishes a calculation model for the 3# water conveyance tunnel of the Fenhe River Diversion Project, and analyzes the variation law of surrounding rock stress and displacement during TBM excavation of the tunnel. The results indicate that the dominant direction of the rock mass principal stress measured by the hydraulic fracturing method is NE84°, and the maximum horizontal principal stress, minimum horizontal principal stress, and vertical stress decrease sequentially, analyzing the characteristics of shield TBM construction technology, it is applied to the construction of water transfer tunnels. The numerical simulation of TBM construction using FLAC3D software shows that as the excavation surface advances, the subsidence value of the tunnel roof first slowly increases, then rapidly increases, and then tends to stabilize. The horizontal displacement of the surrounding rock is increasing. The maximum principal stress of the surrounding rock gradually increases. The final surrounding rock stress is 35 MPa. The TBM shield machine with mud water balance driven by indirectly controlled frequency conversion motor is selected for TBM construction of the tunnel. The study offers statistical information to support tunneling technology for water conveyance in the geotechnical engineering practice.
