From August 10 to August 16, the first neutron measurement uranium logging system independently developed by Donghua University of Technology was tested in the Mongolia-Xinjiang Tianshan Uranium Co., Ltd., Mongolia and Mongolia. Compared with the gamma log, it is found that the detection limit of the system can reach more than two ten thousandths, and the measurement effect is better.
In uranium geological prospecting and in-situ leaching of uranium, the direct measurement of formation uranium content technology has always restricted the development of uranium mining in our country. Especially in the process of underground leaching of uranium, the balance of uranium and radium is severely damaged, and the conventional gamma ray logging can not be used to objectively evaluate the residual uranium content in the mining area. Russia, the United States and other countries use neutron logging technology to better solve this contradiction. China has tried to introduce this technology, but due to technical barriers and other constraints, this technology in our uranium exploration and uranium mining applications has not been able to get it.
Donghua University neutron measurement uranium logging system using multi-detector technology to eliminate the water layer, well tube, cement ring, etc. on the measurement results. In-situ logging at the Montgulg deposit provides further optimization and refinement of the system. It is expected that in the near future, China's internationally-developed neutron logging uranium technology, which is independently developed by China, will be applied in the field of uranium exploration and exploitation, which will bring revolutionary features to the uranium exploration and mining in China breakthrough.
