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. According to the notice of the State Administration of Taxation on printing and distributing the notes of business tax items (Trial draft), Document No. 149 [1993] of the State Administration of Taxation stipulates:
I. transportation instry
(V) loading and unloading
loading and unloading refers to the use of loading and unloading tools or human and animal power to transport goods between means of transport. The business of loading and unloading and handling between loading and unloading sites or between means of transport and loading and unloading sites
therefore, the provision of ore excavation and loading services belongs to "transportation - loading and unloading". The applicable business tax rate is 3%, and "uniform invoice for loading and unloading" or "transportation invoice" should be used

4. The first choice is to buy second-hand excavators with fast cost recovery, low pressure and low depreciation cost. Of course, it also makes money
buy second-hand excavators to Kunshan hengdig Construction Machinery Co., Ltd. as the first choice, I hope it can help you!

7. How many cars a day? How much more
8. Excavators are usually used in open-pit coal mines. If they are used underground, there is no difference between them and the ground. If you want to work, you can find an open-pit coal mine. The underground coal mine requires a lot of excavators to operate underground.
9. By the way, excavators,
excavators are mainly used for engineering construction. Such as: roads, bridges, buildings, breeding ponds, underground engineering, emergency excavation and so on. The main characteristics of excavators are great strength and high efficiency. They can complete projects that cannot be completed by manpower and improve work efficiency. Excavators are needed for general engineering teams, construction instry, emergency departments, and even private (excavation, road, reclamation)
digging machinery is a kind of earth moving machinery which excavates materials higher or lower than the bearing surface with bucket and loads them into transport vehicles or discharges them to the stockyard. The excavated materials are mainly soil, coal, silt, rock and ore after pre loosening
in general engineering, about 60% of earthwork volume, 80% of stripping volume and excavation volume of open pit mine are completed by excavation machinery. Mining machinery is divided into single bucket excavator and multi bucket excavator. The operation of single bucket excavator is periodic, and the operation of multi bucket excavator is continuous.
