In recent years, with the country paying more and more attention to environmental protection and the implementation of the "dual carbon" goal, vigorously promoting the construction of green mines is the only way for mineral enterprises to transform and upgrade and achieve sustainable development.
Since a large amount of dust, waste gas, wastewater and other pollutants will be generated during the development and utilization of mineral resources. If it is improperly treated, it will cause serious pollution to the atmosphere, soil and water resources, and will be ordered to suspend production and rectify according to law. Therefore, it is an inevitable choice to enclose the mining open-pit yards and processing and production.

new intelligent gas membrane environmentally friendly enclosed has the advantages of low cost, fast construction, and high space utilization. The application technology of is currently very mature. As the industry leader, Zhongcheng Space has been widely recognized by relevant industries in environmental protection and closure. This article explains the environmentally friendly and closed application of gas membranes in the process of mining development and utilization.
1. Environmentally friendly and intelligent, meet emission requirements
Pollution control is a key task in the process of mineral resources development and utilization. In recent years, various places have issued corresponding regulations, but many enterprises in many places have been criticized, summoned, warned, and even listed for supervision by the central environmental protection inspection team and relevant environmental protection departments for irregular pollution control.

In terms of environmental protection and sealing of open-air yards, air membrane has obvious advantages. The inside of the air film is slightly positive, which has very good air tightness and effectively prevents dust from spilling out. In terms of intelligent applications, the gas membrane is also equipped with an intelligent monitoring system. Using 5G Internet of Things technology, achieves 24-hour unattended , client views the internal environment of the gas membrane online in real time quality data . Through the internal sensor monitoring system and intelligent fresh air ventilation system, realizes controllable and adjustable indoor air quality, At the same time, a purification filtering and dust reduction device is set up at the gas membrane ventilation port to process indoor dust and harmful gases and discharge them to meet the emission standards , avoids the leakage of dust and waste gases to cause secondary pollution to the environment.
Therefore, the gas film can not only meet the environmentally friendly emission needs in the production and processing process, but also combine the intelligent system with other production links, but also promote the production and processing process to be safer, smarter and more comfortable.
2. The foundation has wide applicability and strong plasticity in appearance
In the development and utilization of minerals, some construction sites are temporary sites, and some sites need to be built near mines... When building sites, foundations with different strengths, slopes and shapes are often encountered. Using traditional structures requires a lot of manpower and material resources to process foundation , which is also difficult to build, so the related costs will also increase; and gas films have incomparable advantages in these aspects.
Due to its light weight, its structural stress is mainly uplifting force and horizontal force. The foundation bearing capacity is mainly the weight of the surrounding foundation wall. The foundation retaining wall has a simple structure and a light weight. Therefore, has low requirements for foundation bearing capacity and is suitable for foundation construction with various geological conditions. At the same time, the gas film has extremely strong plasticity in shape. can customize gas film products in different specifications according to site needs; it greatly meets the construction requirements of different sites in the development and utilization of mineral resources.

3. The cost is 50% lower, the construction cycle is fast, and it can be reused. In environmentally friendly closed construction, the construction cycle, investment amount, and whether it can be reused are all priority factors for enterprises, especially for projects that need to be temporarily closed. These factors have higher priority.
gas film is a new type of space enclosure that uses special membrane materials as the shell, and uses the air pressure difference inside and outside the gas film to support the main body. There are no beams and columns inside the gas film, which can quickly achieve full enclosure, large space and large span. The membrane material uses a special coating and its service life exceeds 25 years. Due to the special structure, the overall cost of gas film is about 30%-50% lower than that of traditional structures; 80% of the engineering volume of can be completed in the processing workshop, and gas film installation can generally be completed in about 1 month. In addition, the superstructure of the air film can realize secondary disassembly and assembly, and reuse . Therefore, in terms of cost, construction cycle and reuse, gas film is the first choice for environmental protection and closure.

4. Energy saving and safety, strong wind and snow resistance
Security is the foundation of enterprise development. Compared with traditional buildings, air membrane has a higher safety factor. In terms of installation, the air film is installed flat, and there is no risk of high-altitude operation. In terms of wind and snow resistance, the air film belongs to a flexible curved surface, and the membrane material itself has good tensile resistance and tear resistance. A steel mesh cable system is added outside the air film to restrict the ductility of the membrane material and make the stress of the membrane material more balanced, effectively improving the safety factor of the gas film structure and the ability of the gas film to resist typhoons and blizzards. At present, the relevant gas membrane projects in have experienced the test of "fireworks" at level 14 typhoon .
gas film material has good light transmission. basically does not need to turn on the light when the light is good during the day. The characteristics of the film material can be used to achieve secondary diffuse reflection at night, greatly saving lighting electricity. Therefore, in later operation, the operating cost of is also relatively low.
gas membrane, as a new solution in the closed application of environmental protection in the mining field, can not only improve the digitalization and intelligence level in the mining development and utilization process, improve the operating environment and operating efficiency of the operating area, but also help accelerate the ecological restoration of mines, meet the relevant requirements of environmental protection inspection, help mineral enterprises transform, and accelerate the construction of green mines.
