High difficulty technology of excavator - mine operation
At the time of the new excavator's top 10 difficult technology, the theme of today's mine is mine operation. The drivers who have opened the excavators in the mine know that the mine is the high risk area of the engineering machinery accident, where the danger index of excavating the machine is quite high, and how dangerous is the danger in the mine? What are the hidden dangers?
1. abominable terrain environment
It is necessary to observe the site before the operation, the mine is located in the high altitude area, the slope is more curved and the machine hand is more demanding. In addition, the private small mine road is relatively narrow, and there is no stone road, it is the soil road, the rainy season can not walk. The above picture is the open pit engineering scene, open the excavator here. Special attention needs to be paid to safety.
2. is responsible for the hidden danger of the stripping operation
For a excavator responsible for stripping in a mine, it is often working on the top of the mountain. The risk index is quite high. The mining team and the residue reverse team try to keep it out of the line, otherwise it will be troublesome. Besides, the excavators are not too much in charge of the mining, and the hidden danger is too large.
3. mine dug is harmful to dug
Excavators work in mines different from other places, such as digging hard rocks in mines. This is a great harm to dug. Machine hands should operate the bucket correctly, adjust the position of the excavator according to the direction of the rock, so that the bucket can be shoveled smoothly, the force can not be too strong when digging, and the tooth root is easily broken.
4. at the time of the security officer's command
Mine safety personnel are also essential. Mining and stripping require a minimum of two safety officers, and need to be equipped with whistles and interphones, because the excavator driver can not watch the rear side slope and the surroundings at any time. The safety personnel need to be observed at the highest point, for example, if no one commands a stone to fall, it is dangerous. One of the hidden dangers of mine safety.
5. mining also needs to repair the slope at the same time
The open pit work has a lot of work and a lot of safety problems. At the same time, the excavator has to repair the slope along with the mining, because some of the slopes are not good for the first time. It is difficult to repair the slope in the back. The purpose of repairing the slope is to reduce the situation of rolling stones and landslides, which is higher for the machine hand.
Do not listen to the sound of the 6. loading operation
The excavation of the excavator on the side of the slope needs to pay more attention to it all the time. Remember not to open the sound of the car or to listen to the song. Under the vibration of a large excavator excavator, the loose mud and stone above can be shattered. The sound is too loud, the commanders' command or other problems can not be heard when they can not hear them.
7. the rolling stones should be paid attention to after the blasting operation
Blasting operations are often carried out in mines. After blasting, special attention should be paid to safety. A full inspection should be carried out ahead of time. There is no loosening of the stone that will fall, or the virtual seam caused by blasting. The machine should pay attention to safety, and ensure that the machine is excavate and then unloaded into the working area after safety.
Summary: because of the special environment and work requirements on the mine, the dangerous degree of the excavator work is greatly increased, and the hidden danger is far more than 7 points mentioned above, and there are many places to be paid attention to.
