Digital Mine Solutions: Digital mines are the product of today's mining science, information science, artificial intelligence, computer technology and 3S technology development. They will profoundly change traditional mining production activities and people’s lifestyles.
China is highly dependent on foreign resources for automation control, evaluation, management, and mining-specific software, which seriously affects the level, efficiency, and credibility of resource evaluation, reserve supervision, and production automation, and reduces the efficiency of mine design and planning. With reliability, it restricts the progress of mine informatization. Therefore, according to the characteristics of China's mineral resources and the actual demand of mining companies for digital mine construction, Dandong Eastern Measurement & Control Technology Co., Ltd. has developed independent knowledge through independent R&D combined with the joint research of production, teaching and research, and seamless interface with third-party software. A series of digital mining key technologies and software for property rights have laid a good foundation for establishing a mining automation industry system with Chinese characteristics. 
Objectives and characteristics:
The digital mine is an important component of the national strategic resource security system and is an important data foundation for evaluating the ecological environment of mine resources. The construction of digital mines is an important cornerstone for the sustainable development of resources and a fundamental way to resolve the risk of high-risk industries.
The construction of digital mines covers a lot of content, and it has just started in China and has broad prospects for development. It is very important for both countries and enterprises. Digital mines were listed as national “863 plans†at the end of 2008. Digital mines use computers and their networks as a means to realize digital storage, transmission, representation, and deep processing of all space and useful attribute data of mines. They are used in various production processes, management, and decision making to achieve optimal production planning and efficient management. The purpose of scientific decision-making.
Digital mines are characterized by the digitization of basic information, the virtualization of production processes, the integration of management and control, and the integration of decision-making processes.

Product classification
1. Pu pneumatic pipe
2. Pu (polyether) pneumatic pipe
3. Pu (polyurethane) bobbin
4. Pu (polyether) bobbin
difference:
Polyurethane pneumatic pipe is over air type. If it is used for over water, its service life will be affected,
Polyether pneumatic pipe can pass air or water, with more stable physical properties and longer normal service life. It is an ideal material for pneumatic pipe.
The bobbin is wrapped with a layer of fiber in the middle of the common pneumatic pipe. Therefore, the bobbin is more solid, pressure resistant and non explosive than the common pneumatic pipe.
Product selection
What should be considered when choosing the type of plastics for blow molding pneumatic pipe?
The following aspects should be considered in the selection of pneumatic pipe materials.
Whether the wall thickness of the welded blank of the pneumatic pipe can be kept uniform, whether a higher blowing pressure is needed, whether the blowing is uniform, whether the surface of the pneumatic pipe is bright, whether the demoulding is easy, and whether the strength can meet the requirements, etc.
Performance comparison of plastics for blow molding pneumatic pipe. The pneumatic tube formed by blow molding is in thermoelastic state, and its density is smaller than that after cooling and shaping, resulting in shrinkage. For the general size of pneumatic pipe is not strict, forming shrinkage has little effect. But for the pneumatic pipes of specified size, such as some hoses used in precision machines, large shrinkage has a considerable impact. The larger the blowing volume is, the more significant the effect is.
The advantages of extruding and blowing plastic forming pneumatic pipe are less investment in production equipment, simple equipment structure, easy mold manufacturing, high forming of pneumatic pipe during production, uniform temperature control, and various specifications of pneumatic pipe can be formed. The disadvantage is that the wall thickness uniformity of pneumatic pipe is poor.
The advantages of injection blow molding pneumatic pipe are that the plastic pneumatic pipe has good product quality, accurate dimensions, no seams, uniform wall thickness, multi-mode molding production, high degree of automation, which is very suitable for large-scale high-efficiency production of small specifications. The disadvantage is that the investment of equipment and molding die is large, and the operation and production need skilled workers.

Tips for pneumatic pipe
Polyurethane pneumatic hose is suitable for compressed air, ordinary industrial water and non corrosive oil. In order to maintain a long service life, it must be used under rated working pressure and ambient temperature. As the temperature rises, the working pressure should be reduced accordingly. If it exceeds the limit, the hose may break. If the fluid temperature is too high or the fluid is corrosive, the hose may break. If the working environment temperature is too high or there is chemical gas in the working space, the hose may crack. If the hose is stored in a wet place or the storage period is too long, the hose may hydrolyze or age, which may lead to fracture
