Mining excavator

1. 1b is one billion, which translates to one billion. So his total is one billion yuan

2. No, it's not tonnage, it's not technology. Excavators are multi-purpose, there's no strict distinction, but different devices are installed when the work is different, such as crushing in stone mine, bucket with good wear resistance in iron mine, and so on. Of course, for open-pit mines, large excavators are selected, as you said, more than 60 tons, in order to save cost and improve efficiency.

3. The mine must use machinery. Without machinery, can it be moved by manpower
as for which excavator or loader is used more, go and investigate the mine by yourself! Excavator is mainly digging, loader is mainly loading.

4. Bucket wheel excavator for open pit coal mine. As for brand, it depends on personal preference
bucket wheel excavator is an important equipment to complete the mining work in the continuous mining process of mining, transportation and drainage. It is used in large-scale projects with large mining volume and long service life, especially suitable for open-pit mine, large-scale earthwork and other applications
wheel excavator has the advantages of large proction capacity, high efficiency, suitable for mining in complex coal seam, large transportation slope, simple operation, convenient maintenance and easy to realize modern management, which is widely used in foreign instrial developed countries
the fuselage is generally composed of bucket wheel excavator, which is composed of bucket wheel machine, transfer machine and connecting bridge.

5. Use Carter and Kato. These machines are powerful! Komatsu can do it! If you have enough money, go to Guangdong and Hong Kong to buy the original imported from Japan! Capital is tight, buy domestic joint venture machine, installment!

6. 1. The poor terrain environment of the mine
the site must be observed before the operation. The mine is located in the high altitude area, with many ramps and sharp bends, so the requirements for the operator are relatively high. In addition, the roads of small private mines are relatively narrow, and there are no stone lined roads. They are all dirt roads, so they can't walk in the rainy season. The picture above is the scene of the open-pit mine project. Special attention should be paid to safety when driving excavators here
2. There are many hidden dangers of excavators responsible for stripping operation
for excavators responsible for stripping operation in mines, they often work on the top of the mountain, which has a high risk index. The mining team and the slag transportation team should try not to be in the same line, otherwise it will be troublesome to roll down the stone. In addition, the excavator responsible for stripping ring mining should not be too many, otherwise the hidden danger is too big
3. Rock excavation in the mine does great harm to the bucket
excavator working in the mine is different from other places, such as digging hard rock in the mine, which does great harm to the bucket. The operators should operate the bucket correctly, adjust the position of the excavator according to the direction of the rock crack, so that the bucket can shovel in smoothly. The force should not be too strong when digging, and the tooth root is easy to break
4. Always obey the command of the safety officer
the safety officer in the mine is also essential. Mining and stripping need at least two safety officers to cooperate, and need to be equipped with whistles and walkie talkies, because the excavator driver can't observe the situation of the rear slope and the surrounding at any time, and the safety officer needs to observe at the highest point. If no one commands, it is dangerous for the rock to fall, This is also one of the hidden dangers of mine safety
5. At the same time of mining, slope repair should be carried out along the way.
open pit mining has the characteristics of heavy workload and many potential safety hazards. Excavator in mining at the same time, but also by the way to repair the slope, because some slope you first repair is not good, to the back to repair it is very difficult. The purpose of repairing the slope is to rece the occurrence of rolling stones and landslides, which requires higher requirements for the manipulator
6. Don't listen to the sound when loading the truck.
when the excavator is working on the slope, you need to pay more attention all the time. Don't turn on the sound in the car or listen to the music. Under the vibration of the excavator in large mines, the loose mud and stones above may be shaken down. If you play it too loud, you can't hear the commander's command or other problems
7. Pay attention to the falling stones after blasting operation
blasting operation is often carried out in mines. Special attention should be paid to safety after blasting, and all-round inspection should be carried out in advance to see if there are loose stones that are about to fall or empty joints caused by blasting. The operator should pay attention to safety, and excavate and mp before entering the working area.

7. The difference between the mining version and the ordinary version of the excavator is that the thickness and strength of the steel plate of the big frame are the same. The hydraulic pump and engine of the excavator with the same configuration are the same, but the tuning power is slightly different. The mining version is more resistant to operation, and the ordinary version is suitable for excavation and infrastructure construction. A typical mine excavator is Carter

8. All open-pit excavator drivers are mobile, two-way choice, in order to work, need to work in the coal mine acquaintances recommended, and then contact the boss, the general is such a procere. The salary is about 6000-7000
as for open recruitment, only a small number of those who are in urgent need of a large number of excavator drivers in a short period of time will do that, generally around 5000, depending on your skills. The conditions there are tough, with two years of work experience and a salary of 5000 yuan.

10. There are excavators for sale on Yehai Avenue in Xiuying District of Haikou. You can also go to Nanhai Avenue, but Haikou mine doesn't really have one
