In October this year, Jinchuan Group Co., Ltd. No. 2 Mining Area investigated the Luziyuan lead-zinc mine of Yunnan Zhenkang County Hongjun Mining Development Co., Ltd., Taoping lead-zinc mine of Baoshan Feilong Nonferrous Metals Co., Ltd., Maoping tungsten and molybdenum mine of Jiangxi Yaosheng Tungsten Industry Co., Ltd., and lead-zinc mine of Hunan Baoshan Nonferrous Metals Mining Co., Ltd. After investigating the paste filling system of Luziyuan lead-zinc mine of Hongjun Mining Development Co., Ltd. in Zhenkang County, Yunnan Province, Feishan Feilong Nonferrous Metals Co., Ltd., Taoping lead-zinc mine, Jiangxi Yaosheng Tungsten Industry Co., Ltd. Maoping tungsten and molybdenum mine, and Hunan Baoshan Nonferrous Metals Mining Co., Ltd. lead-zinc ore ore paste filling system, it is believed that the "nanny" after-sales technical service of Feny Co., Ltd. is very in place. For example, in the early stage of the operation of the Luziyuan lead-zinc mine filling system of Yunnan Zhenkang Hongjun Mining Development Co., Ltd., Feny Co., Ltd. composed of a special research team composed of deputy general manager, deputy chief engineer and laboratory director, carried out nearly a month of on-site tests and tackling key problems around the underflow concentration, filling strength and pumping capacity of the thickener, and completely solved the problem, and the filling station ran without failure for more than 4 months, running for more than 16 hours a day, and the total amount of filling reached 280,000 cubic meters, exceeding all the parameters of the original design plan. At present, the filling technology and complete sets of equipment and green mine operation services have been applied in more than 200 metal mines, chemical mines and coal mining enterprises under different geological conditions at home and abroad under China Gold Group, China Minmetals Group, China Nonferrous Metals Group and other companies, all of which are one-time successes, completely solving the problem of "green, environmental protection, safety and efficiency" for users, and winning unanimous praise from mine users.

As the reporter's understanding of Feny shares becomes deeper and deeper, the more he feels that this scientific and technological innovation enterprise is not simple. With the persistent pursuit of scientific and technological innovation, starting from the research and development of a single core equipment, the whole industrial chain of paste filling has been opened, such a lasting and systematic innovation, such advanced core equipment, such a high-end scientific and technological platform and a top scientific and technological talent team, let the reporter be amazed, especially as a private enterprise, it is very rare. Soon after the reporter's interview, there was exciting good news from Feny Co., Ltd.: based on the company's professional technology and services in the field of paste filling, Jinchuan Group Co., Ltd. signed the "Paste Filling Cooperation Framework Agreement" with it after full investigation, and will carry out the application demonstration of green mining technology for paste filling and operation in Jinchuan Group. The project will not only solve a series of problems such as tailings storage (discharge), land occupation and pollution in the second mining area of Jinchuan Group, but also make greater progress in the mining area of "one waste and two treatments", and explore the sustainable development path of green mining in the mine, and through the environmental protection treatment method of paste filling, it will also save most of the environmental protection tax, with outstanding ecological and environmental benefits and good economic benefits. 

The reporter believes that Jinchuan Group will be like Hunan Gold Baoshan Mining, with the help of the advanced technology of Feny Co., Ltd. paste filling, to embark on a road of innovation and development of green mining and ecological civilization construction. And this is only the prelude to the construction of ecological civilization in mines. In May 2018, General Secretary Xi Jinping emphasized at the National Conference on Ecological and Environmental Protection that it is necessary to speed up the delineation and strict observance of the three red lines of ecological protection, environmental quality and resource utilization. We must not do it again, and we will never allow it to do it again, and we will never allow it to be done again, and we will never be allowed to do it again. 

From the words of the general secretary, we strongly feel that the Party Central Committee attaches great importance to and urgently requires the construction of ecological civilization. With the continuous and in-depth promotion of the construction of "Beautiful China" and "Ecological Civilization", the rigid demand of mining enterprises for ecological environmental protection will become stronger and stronger, and paste filling, as an advanced environmental protection practical technology recognized by industry experts and academicians and experts and has been verified in practice, will play a key role in the environmental protection treatment of mine tailings and tailings ponds, coal gangue and other solid wastes, and make important contributions to the construction of mine ecological civilization in China.

 What makes the reporter happy and proud is that the advanced key technology of paste filling is completely mastered by our national enterprises. We look forward to more application cases of mine paste filling technology in Shenzhou.
