After the countdown 3, 2, and 1 instructions are issued, the high-pressure spray water cannon truck starts and starts spraying at the blasting point. After the blasting sound, the dust was quickly suppressed in a short period of time, and no stones were seen flying out of the scene. On October 26, at the dust-free blasting demonstration site of the China Communications Construction Company Space Administration Mine, journalists from many Latin American countries were deeply shocked by the scene and picked up their mobile phones to record and take pictures.

The last stop on the Tianjin line of the "Reading China" activity is Jizhou District, known as the "Back Garden of Beijing and Tianjin". Journalists from 13 Latin American countries visited the Jizhou Mine Ecological Restoration Project of CCCC Aerospace Bureau to gain an in-depth understanding of China’s innovative achievements in ecological restoration and sustainable development.

"Dust is a world-class mine ecological restoration problem. We used domestic advanced dust reduction equipment and facilities during the blasting process and used dust-free blasting technology to overcome this problem." Blasting from the Jizhou Mine Ecological Restoration Project Department of China Communications Construction Company Aerospace Bureau Expert Tang Xianxi introduced.

Tianjin Jizhou District is located at the intersection of the North China Plain and the Yanshan Mountains, with a total area of about 1,590 square kilometers, half of which are mountainous areas and plains, and is very rich in mineral resources. In the 1980s and 1990s, due to disorderly mining, many large and small wounds were left on the local mountains. At present, Jizhou has implemented comprehensive environmental protection and restoration of mountains, water, and human settlements. Among them, the environmental restoration projects of Bieshan Mining Area and Xiwubaihu Mining Area will effectively eliminate hidden dangers of geological disasters and secondary damage to the environment.

After visiting the dust-free blasting demonstration, the foreign media reporters came to the Jizhou Ecological Restoration Exhibition Hall to gain a comprehensive and three-dimensional understanding of the planning, implementation, and construction results of the mine restoration project as well as the black technology behind the mine restoration. It is understood that the Jizhou Mine Ecological Restoration Project of CCCC Aerospace Bureau covers an area of approximately 637 hectares. The construction content includes geological disaster management, ecological environment restoration, remaining stone processing services, and the introduction of ecological industries. For the first time, "high-pressure spray water cannon" will be used "Car-free blasting" technology was introduced into the ecological restoration project of abandoned mines.

Later, foreign media reporters walked into the green and environmentally friendly aggregate processing intelligent monitoring center. Chen Lei, executive deputy manager of the Jizhou Mine Ecological Restoration Project Department of China Communications Construction Company Aerospace Bureau, said, "The entire production process of aggregates is fully unmanned, and people will only intervene when a failure occurs. The smart large screen in the control center will display All technical parameters indicate whether production is normal."

During the discussion and exchange session, Cao Xingkai, project manager of the Jizhou Mine Ecological Restoration Project Department of CCCC Aerospace Bureau, introduced in detail the "Chinese model" of abandoned mine restoration and shared relevant cases and experiences.

Several reporters, including César Eduardo Romero Calle of Peru’s La Repubblica and Leticia Martinez of Argentina’s public radio station, asked about the application of mine restoration technology in their country and said, “In There are many companies mining in Peru, Bolivia, Chile and other countries. Can mine restoration technology be added to the mining process and restored at the same time?" In this regard, Cao Xingkai said: "Currently, Chinese companies attach great importance to the ecological protection of mining areas. In the 'green mine' 'Under the concept, the local ecological environment will not be damaged during mining. We very much hope to reach cooperation with Latin American countries."

Journalists from many countries are full of expectations for the future cooperation between their countries and China in mining projects. “Mine protection is a very important project.” Jason Jaén Uréña, a reporter from Costa Rica Today, said, “Costa Rica attaches great importance to environmental protection, and I believe there will be cooperation between the two countries. Some collaboration.”

Liliana Padilla Guerrero, a reporter for Mexico's Millennium newspaper, said: "I think this project is very interesting because mining plays a very important role in the development of Mexico. In the process of mining development, , has also produced a series of pollution problems. The mine restoration projects I saw here and the industries developed based on mine restoration can not only promote the development and progress of Mexico's mining industry, but also promote the development of Mexico's economy."

The "Read China" Hebei-Tianjin line event is guided by the Cyberspace Administration of China and co-sponsored by the China Public Diplomacy Association and Global Network. The event will last until October 28. After the Tianjin trip, foreign media reporters will visit Tangshan in depth and experience check-in points such as Tangshan Food Culture Museum, Tangshan Industrial Museum and Tangshan Nanhu Kailuan Tourist Area to experience Tangshan’s profound cultural heritage, folk customs and technology. modernization development process.
