Abstract The exploration of the origin of hot spring is the basis of its development and utilization. There are many low-medium temperature hot springs in Nanjing and its surrounding karst landform areas, such as the Tangshan, Tangquan, Lunshan, and Xiangquan hot springs. This article discusses the origin characters of the Lunshan hot spring with geological condition analysis, hydrogeochemical data, and isotope data. The results show that the hot water is SO4–Ca type in Lunshan area, and the cation content of SO4 is high, which are related to the deep hydrogeological conditions of the circulation in the limestone. Carbonate and anhydrite dissolutions occur in the groundwater circulation process, and they also dominate the water–rock interaction processes in the geothermal reservoir of Lunshan. The hot water rising channels are deeply affected by the NW and SN faults. Schematic diagrams of the conceptual model of the geothermal water circulation in Lunshan are plotted. The origin of Tangshan, Tangquan, and Xiangquan hot springs are similar to the Lunshan hot spring. In general, the geothermal water in karst landforms around Nanjing mainly runs through the carbonate rock area and is exposed near the core of the anticlinal structure of karst strata, forming SO4–Ca/SO4–Ca–Mg type hot spring with the water temperature less than 60°C. The characters of the hot springs around Nanjing are similar, which are helpful for the further research, development, and management of the geothermal water resources in this region.

Deep Boreholes

In deep geothermal boreholes, an effect of temperature (so-called thermal lift) is observed, which results in the volumetric expansion of the fluid extracted. This process results in increased wellhead pressure values being recorded; in the absence of an appropriate correction, hydraulic properties of the reservoir layer cannot be properly determined. As an example of this effect, the Chochołów PIG-1 (CH PIG-1) geothermal borehole situated in Podhale Basin in Poland was used. Hydrodynamic tests including two pumping phases were carried out in the well in order to establish the basic hydraulic properties related to the determination of its operational resources (maximum water extraction value–capacity) and permissible groundwater level. Particular attention was paid to the thermal lift effect in the borehole. The conductivity, which depends on the pumping level, could be two to three times higher with temperature correction than results without any correction. The goal was to analyse the variability of the observed physiochemical properties of the exploited geothermal waters and to determine the correlation between the properties analysed and the temperature of the geothermal water. For the relationship between temperature and the observed pressure at the wellhead, the value of the correlation coefficient was negative (a negative linear relationship was determined), which means that as the temperature increases, the wellhead pressure decreases. The hydrodynamic tests carried out in the CH PIG-1 borehole and the analysis of variability of selected ions and parameters in exploited water were necessary to assess the possibility of increasing the efficiency (Q) of the CH PIG-1 borehole and to determine the water quality and its natural variability. Such information is crucial for the functioning of the recreational complex based on the use of geothermal water. A study of the phenomena affecting the exploitation of hot water from deep boreholes enables their effective exploitation and the use of resources in accordance with the expectations of investors.

Objectives. The aim of the study is to develop a method of operating geothermal energy systems in the mode without scaling when disposing of flammable gases with geothermal water in wells with a low gas factor.Method. The studies were conducted on the basis of analyzing the content of associated flammable gases in the underground thermal mineral waters of the North Caucasus and Ciscaucasian deposits and assessing the possibility of their utilization and use for heating and hot water supply. In this case, the laws of dissolution and desorption of methane and carbon dioxide from groundwater solutions with the content of scale-forming components, in particular, calcium carbonate, are used.Result. On the basis of the conducted research, it was found that the operation of g eothermal systems in the power industry should be carried out after preliminary withdrawal of the maximum possible amount of associated flammable gases from a water solution, while maintaining the content of carbon dioxide in water at a level above the equilibrium value. The scheme of the effective operation of thermal distribution stations with the prevention of carbonate deposits in them is given by using the products of associated gas combustion in the waste water when it is pumped back into the aquifer.Conclusion. As a result of the research conducted, a method of operating geothermal energy systems in a non-salt-scale mode has been developed for utilization of combustible gases associated with geothermal water. It has been established that in order to accelerate the dissolution of carbon dioxide in water to stabilize it before entering heat-exchange equipment, it is advisable to increase the partial pressure of carbon dioxide to values exceeding by an order of magnitude the equilibrium at a given temperature. At the same time, before pumping waste water back into the aquifer, excess carbon dioxide is removed from the water.

The development of the Toguraci Underground Mine was begun in 2011 with the ore production started in 2012. The amount of water continued to increase in the Underground Mine at the beginning of 2014 which became problem that effected the activities of mining. The increase of hot water Toguraci underground mining effected to the safety for workers who are exposed to hot water, ventilation problems and equipment that are submerged in hot water. Tuguraci mine has two dewatering systems, namely dewatering systems on the surface and dewatering systems in underground mines. The handling of surface water comes from pumping underground to surface where water discharge is around 400 L / s with the temperatures ranging from 70°C while water treatment in underground mines includes decreasing water heading levels and pumping water from underground mines to the surface. The increase water entering heading development and stoping can be overcome by changing the surface dewatering system by using water cooling, while underground mining is done by changing the pipeline from the polypipe to the steel pipe and to reduce water entering the mining front is doned by drill holes for installing submersible pumps and replacing Oddesse pump to the Schlumberger pump which is more resistant to high temperature hot water, as long as mining operations take place 48 borehole drilling has been done with 11 borehole flowrate below 5 l / s and 37 borehole with flow rate above 5 l / s, and a water drop of around 77 meters

Geothermal resources are abundantly available, low-cost, renewable, and clean. Therefore, the exploitation and utilization of geothermal resources would exert a great influence on society and economy. Fuzhou geothermal, which is on behalf of the medium and low temperature magmatite rock fissure type geothermal, is often with surface thermal manifestations and distributes zonally along the tectonic fissures. Aiming to investigate the origin of the Fuzhou geothermal field, this paper takes Fuzhou Guihu geothermal field as the research object, analyzing its geothermal background of regional tectonic characteristics. Special analyses of the geothermal water chemical and isotopic characteristics (including the formation and origin mode of ground water constants and trace elements, D/18O isotopes) revealed that the underground hot water of Guihu was originated from precipitation and formed by the heating effect of the deep geothermal circulation. Based on isotopic fractionation, the calculated precipitation infiltration recharge elevation for the Guihu geothermal water is 536.3m. In the light of the surrounding topography, it is reasonably inferred that the Jialiang Mountain is the recharge source of the Guihu geothermal water.
