Abstract:Xiling gold deposit is located in the deep part of Sanshandao gold deposit. It is the deepest explored deposit in China at present. Accompanying with the deepening of exploration and development of the deposit, existing evaluation results are no longer able to meet the requirements of deep ore body exploration and development. According to the results of three lateral resistivity, density and acoustic logging, combining with drilling engineering geological logging and rock physical and mechanical property sample testing, deep engineering geological conditions of deposits have been studied. According to the spontaneous potential, three lateral resistivity and caliper logging results, combining with engineering geological logging, hydrogeological conditions of the deposit have been studied. By using well temperature and natural gamma ray logging technology, combining with deep well laboratory data, the environmental geological conditions, such as heat damage, radioactive damage, Rock burst, rock burst and other underground disasters that may be caused by deposit mining have been studied. Variation rules of mining technical conditions in the deep part of the deposit have been summarized. It will provide reliable technical parameters and guidance for deep well mining and thermal protection engineering.
