Picture of excavator digging mine

1. 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.

2. 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.

3. 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

Terex rh400 excavator is the largest excavator in the world. There are six excavators in the world. The first one was manufactured in 1997, and the improved sixth one was launched in 2002. Among them, the fifth one is electric driven. The diesel engine version uses two Cummins qsk60-c diesel engines (16 cylinders, turbocharged) with a tank capacity of 16000 L. five of the six excavators are in the United States One is used in a Canadian mine, with a total weight of 1008 tons, a maximum power of 4398 horsepower and a bucket capacity of 43.58 cubic meters

extended data:

excavator, also known as excavation machinery, also known as excavator, is a kind of earth moving machinery that uses bucket to excavate materials higher or lower than the bearing surface, and load them into transport vehicles or unload them to the stockyard

the materials excavated by excavators are mainly soil, coal, silt and soil and rock after pre loosening. From the development of construction machinery in recent years, the development of excavator is relatively fast, excavator has become one of the most important construction machinery in engineering construction. The three most important parameters of excavator are operating weight (mass), engine power and bucket capacity

7. Brother, there are still people asking this question. There are lots of pictures on the Internet. Or go to some excavator platforms to find many

for example, China excavator network is very good, and I sometimes go to understand it. ha-ha!
