Potential Evaluation And Development Benefit Analysis Of Shallow Geothermal Resources In Main Economic Zones Of Datong

Under the ground of 0-200 meters within the depth of rock soil layer,or in the depth range of the ground or underground water exists in the average temperature in the thermal energy of 25 DEG C,the shallow geothermal development and utilization of the heat energy is the property to be discussed in this paper.The current academic circles energy due to the repeated use of green energy sources,mainly used to replace coal and other solid fuels for heating and daily mediation as the main material,so it can reduce emissions of carbon dioxide and other pollutants produced by burning in the conventional energy and material saving.Through the reasonable development and use of shallow geothermal energy At the national level,the safe use of ordinary energy and the related environmental problems arising therefrom can be guaranteed sufficiently,and the active implementation of the restructuring of the energy use structure in the country can be ensured.The establishment of harmonious ecological and social living environment has great practical value.Research in this thesis is mainly around the economic zone of Datong in the storage situation of shallow and low temperature energy were collected in the study.The geological hydrology data scope of main economic zone in the city,and after the test of physical and thermodynamic properties of soil strata which contains collection of relevant area.The shallow geothermal contained in the study area can be partitioned and evaluate the suitability of development level,and comprehensive assessment of regional economy in the geothermal energy economy environment benefit can produce development.After the temperature of heat storage unit volume algorithm related calculation can be drawn,the study of shallow geothermal energy content in the range of single temperature 2.39*1014 kJ main economic zone for Datong is,is 665*108 kwh.The equivalent of 8 million 180 thousand tons of coal combustion and combustion generated by the ordinary and the energy it is said that this area has the repeated use of shallow geothermal energy content is considerable.And through the study to evaluate the potential is based on the large geothermal reserves can be generated in the development and use of all aspects of its economic benefit,environmental benefit is great Big.
