What Are The Precautions For The Safe Operation Of The Shotcrete Machine

We must know that the proper operation of the mine shotcrete machine is the top priority, so we must prevent electric shock. Be sure to check carefully before use to ensure that the explosion-proof equipment of the machine is intact and the load cable is intact. At the same time, the explosion-proof switch and spray switch should be powered off to prevent misoperation.

The second is the need to pay attention to transportation. It generally includes four aspects: the interval between the machine and the track, and the interval between the two workers. This distance is mainly to prevent accidental bumps, accidental bumps and accidental injuries between two people. It is also necessary to know in advance whether it is manual or active. This is very important and requires special attention during mechanical operation. And whether the material is placed on the car or on the ground also needs attention.

Next, it is worth paying attention to whether the water supply and gas supply of the shotcrete machine, whether the joints are reliable, whether the fixing is firm, whether the shotcrete pipe is intact, whether the explosion-proof preparation is sufficient, and whether the sprayed concrete pipe is qualified, also need to be paid attention to. This aspect primarily includes inspection of diameter, material and wall thickness. If it fails, it needs to be replaced immediately.

Then there's shotcrete. There are also a number of noteworthy aspects in this regard. It is important to make sure that the cement blaster is solid and has enough support to complete the blasting job. The distance between the shotcrete surface and the slurry pipe also needs to be paid attention to to prevent the rebound from hurting people.
