Publish: 2021-05-23 02:26:16
1. Take exit D or exit e, go straight to the crossroads and cross the road to the hall where there are a few ~!
2.
There are six exits in the exhibition center station:
A1 exit: To Greater China International Trade Plaza and other places
Exit A2: access to Jintian Road, Greater China International Trade Plaza, etc
Exit B: it leads to Zhongxin 4th Road, Fuhua 1st Road, etc
Exit C: it leads to central 4th Road, convention and Exhibition Center, International Chamber of Commerce Center, information hub building, etc
Exit D: to Fuhua Third Road, Exhibition Center (North Gate), Century Center home Plaza, etc
Exit e: access to Jintian Road, Century Center home Plaza, etc
3. Walk 470 meters from exit d to
4. The main entrance of the exhibition center is hall 1, and the right front end is hall 8. All the way, there's a map of an exhibition.
5. The nearest exit is exit C, but it's only the nearest. The straight-line distance is more than 600 meters. It takes about one kilometer to walk. The normal speed is about 15 minutes. The south bus station of the Convention and Exhibition Center is on Binhe Road. It seems that there is no other convenient subway transfer mode. Registration map
6. 1 (1) in the same coal seam in the same mining area, it is not allowed to arrange three or more mining faces and more than five driving faces to work at the same time
(2) organize proction in strict accordance with the standard of fixed number of personnel
(3) long wall mining should be adopted in coal mines where conditions permit, and room pillar or short wall mining method can be adopted in coal mines with continuous miner. When mining triangle coal, resial coal pillar or re mining, there must be operation proceres and safety technical measures approved according to regulations
(4) the working face of coal or gas outburst mine, high gas mine and low gas mine in high gas area shall not adopt the forward mining method, and the working face must maintain at least two smooth safety exits, one to the return air lane and the other to the inlet air lane. When the triangle coal and resial coal pillar cannot maintain two safety exits, the operation proceres and safety technical measures approved according to the regulations must be in place

GJ -- total amount of driving coal in the first three years, 104t
GC -- the total amount of coal extraction in the first three years, 104t< According to the average proction capacity of the mining face and the amount of coal excavated in the previous three years, the average annual mining proction capacity of the mine in the previous three years (unit: 104t / a) a:
the average annual mining proction capacity of the mine in the previous three years can be used as the approved proction capacity of the mining face.

The regulations on gas concentration of return air flow in heading face in coal mine safety regulations are as follows:
① when the gas concentration in return air roadway in mining area and return air roadway in mining face exceeds 1.0% or the carbon dioxide concentration exceeds 1.5%, the work must be stopped, the personnel must be withdrawn, and measures must be taken to deal with it
(2) blasting is strictly prohibited when the gas concentration reaches 1.0% in the air flow of the mining face and other operation sites, or within 20m near the installation site of the motor or its switch. In the mining face and other roadways, when the concentration of gas accumulated in the space larger than 0.5m3 reaches 2%, the work must be stopped within 20m nearby, the personnel must be withdrawn, and the power supply must be cut off for treatmentfor the electrical equipment whose power supply is cut off e to the gas concentration exceeding the regulation, it can only be powered on and started when the gas concentration is below 1.0%. When the gas concentration exceeds 1%, when the carbon dioxide concentration exceeds 1.5%, the power must be cut off
extended data:
by 2009, the mechanization degree of state-owned key coal mines is 85.5%, the fully mechanized mining degree is 75.79%, and the fully mechanized mining degree is 25.87% [13]. For rock roadway driving equipment, there are mainly drilling, support, loading, transportation and auxiliary equipment
(1) the development of rock drilling equipment mainly experienced hand-held rock drill → air leg pneumatic rock drill → hydraulic (pneumatic) rock drill jumbo and hydraulic rock drill (2) the supporting equipment mainly includes bolt drilling equipment and shotcreting equipment. The development of anchor drilling equipment mainly experienced electric anchor drilling machine → climbing rod anchor drilling machine → drilling car anchor drilling machine → outrigger pneumatic anchor drilling machine → airborne hydraulic anchor drilling machine (3) the main shotcreting equipments are wet shotcreting machine and wet shotcreting machine (4) the development of waste raking machinery has experienced the following stages: manual rock loading → bucket rock loading machine → side mp bucket rock loading machine → bucket rock loading machine (5) the development of transportation machinery has mainly experienced the following stages: hand cart → 4-5 t electric locomotive and tramcar → belt (transfer) conveyor → bin train and shuttle tramcar (temporary gangue bin). The development of rock roadway driving equipment provides more convenience for the proction of efficient mechanized driving and its operation line8. Local conditions and customs
although Australia is often portrayed as a country dominated by rural areas, in fact, it is still dominated by urban culture and metropolitan lifestyle, including delicious food from all over the world
Australians like to drink beer. In their spare time, especially on weekends, many people like to go to bars with friends for drinking and talking, listening to music, or having a barbecue in the park. Australia's cities give people a sense of openness, with many open parks and green spaces dotted between them. Most of the parks in Australia are free of charge. They don't even have walls. There are paths in and out of the park in all directions. Convenient transportation can also effortlessly bring people into the national parks in the suburbs of the city
lifestyle
freedom is the best generalization of Australians. Australia has a strong atmosphere of freedom and freedom. People call each other by their first names (only by their first names, not their surnames) every day. This is true between employers and employees, teachers and students. In the center of Sydney and Melbourne, white-collar workers or white-collar beauties in stiff suits and their friends and colleagues can often be seen at noon, sitting on the front steps of buildings to eat simple lunch, such as sandwiches or hot dogs, while white-collar workers sit on the street to eat Bento, which is also a modern metropolis, The same scene is unimaginable in places like Tokyo or Hong Kong.
