Emptying during maintenance of lining plate of ore pass drawing
In the forum session of this summit, the guests on the scene had an in-depth discussion on the theme of "trends and trends of media", and made wonderful interpretations according to their own enterprise characteristics and instry experience. Ms. Ma Jinghua, former vice president of public relations of BMW Huachen, brand director of Volkswagen and now vice president of International Department of Dalian Tiansi museum ecation group, said:
I very much agree that any business must have a strategic goal. Its vision, mission and goal should be clear. 5g and blockchain are technologies, and this primary and secondary must be clear. Especially in the future, brand communication is very important. The basic principles of brand building, the relationship between elements and consumers, how to maintain the value of the brand, how to measure the value of the brand, and the basic business rules will not change. I hope you can work hard to understand these rules, learn these things and keep them in your mind, At this time, you won't lose your direction when the big waves come, and you won't be dazed by the colorful technology
specifically, 5g is characterized by low delay and high transmission speed, which puts forward high requirements for the quality of media personnel and public relations personnel. Then there are changes in the channels and methods of content distribution. The Internet of everything, media of everything, smart city and smart home brought by 5g, including everyone, have become media. In this case, how do you influence the public and spread your information? We should consider it from a higher level, because of its low delay, high speed, coupled with the rise of short video, the sense of customer experience is high, and the requirements are also high. As a public relations and media, how to adapt
as a media company or media personnel, we should have a clear strategy. What should my company do when the two technologies are interwoven. In my opinion, 5g or blockchain is actually the best tool to improve influence. We seize this opportunity, conform to this trend and take advantage of it to strengthen ourselves. It's an opportunity. It's an era of influence. It's very rare
I learned a little bit about blockchain because one of my classmates wrote the first book on blockchain technology popularization in China. As Mr. Fu said, the core of blockchain is the protection of the originator, the protection of the originator and the works, which gives the originator a platform and standard to measure their self-worth and procts. This provides a great protection for the creation of media and the creation of content by media practitioners. In the future, as long as everything we write is good and unique, there will be more than n people to buy and praise it. In fact, it has become very popular in the United States
blockchain is also helpful for distribution channels. Any rough and disorderly things you make will have traces, and the good things you write will be confirmed, widely quoted, and create higher value. You have the right to be yourself. Therefore, media companies must make blockchain strategy as soon as possible, seize the opportunity

on the basis of making full use of the existing proction and living facilities and natural conditions of the mine, a safe, environmental protection and resource utilization mine should be built with less investment. We should make full and reasonable use of the mine's geological reserves, adopt suitable mining methods, and recover as many geological resources as possible. In order to improve the economic benefits of the mine, we should make full use of the existing facilities and equipment of the mine and increase the investment as little as possible. Select and use the mature technology in our country, and the mining and processing equipment with high degree of mechanization and energy saving which are suitable for the mining and processing conditions of the deposit have been adopted and mastered by the mine. On the premise of meeting the normal proction of the mine, auxiliary facilities should be simplified or entrusted to social forces to rece investment< Second, the main scheme design of the mine construction
the development system adopts the footwall shaft development scheme, = 5500mm. The shaft is used to lift up and down the ore, waste rock, personnel and materials. The single-layer double cage is used to lift. The wellhead elevation is + 59M and the bottom elevation is - 315m. In the footwall of the ore vein, there are seven stage transportation roadways (0 m, - 50 m, - 100 m, - 150 m, - 200 m, - 250 m and - 300 m), which are arranged outside the moving zone of the ore body, because they are used as the return air roadways in the previous stage, and are lifted in multiple middle sections
the thickness of the ore body is generally 5-30m, with an average of 16.8m, and the dip angle is about 60 °, It belongs to steeply inclined medium thick ore body. The ore body is mainly composed of copper bearing pyrite. The proctor's coefficient f is 6-8. It belongs to relatively solid ore body, but it mostly contains fracture structure and fracture zone, so the stability of ore body is not very good. The hanging wall rock is unstable, and the footwall rock is relatively stable. The ore body contains sulfur, and has certain caking and oxidizing properties. Therefore, the filling mining method can only be used, but if it is well controlled, the sublevel caving method is also technically feasible. According to the design task, it is a small and medium-sized mine. Combined with the geological data, it adopts the drift mining method of reinforced concrete false roof sublevel caving method. The stage height is 50m, the length of ore block is 50m, and the width is the width of ore body. The ore blocks are arranged along the strike, and each ore block is provided with a pedestrian lifting raise and a pass mine. After the ore caving, it is transported by an electric scraper and poured into the pass through the connecting road, After that, the ore passes through the ore pass to the ore bin, and the vibrating drawing machine is used for ore drawing.
