Mine equipment operation safety risk points and prevention and control

(3) Prevention and control of security risks. Mine safety personnel or production management personnel shall strengthen the inspection of the driving behavior of drivers and supervise the work of drivers strictly in accordance with the relevant management system of automobile road transport. The violators will be dealt with severely.

The driver should develop the habit of daily maintenance and inspection of the vehicle before operation every day, timely discovery of the safety hazards of the vehicle, timely elimination, and strictly prohibit the vehicle from operating with illness.

Overspeed and overloading of vehicles are strictly prohibited in the mine operation area. This kind of driving behavior is prone to safety accidents on the bad roads in the mine working area. Heavy rain, snow and bad weather should stop the transport. Even if you want to transport, you should add some anti-slip and anti-trap safety facilities to the car to ensure the safety of the car in bad weather.

Stone mine production enterprises should not arrange night work as far as possible, because the night light is not enough, the road condition in the mine operation area is complex, which is easy to lead to safety accidents. It is necessary to strengthen the inspection and maintenance of motor vehicles to ensure that the front and rear lights of motor vehicles are normal and the brakes are sensitive and reliable.

(7) Safety risks and prevention and control of mine waste splitting operation

There are artificial wedge splitting, mechanical splitting and air bag splitting in the process of mining. At present, the most commonly used splitting method is mechanical splitting.

Artificial wedge splitting is the oldest and most backward stone mining process, which is gradually dying out and being replaced by new stone splitting technologies. Although the artificial mold splitting technology is simple and backward, it is still in use because of its low mining cost and low technical requirements.

The splitting machine of stone in stone mining is also called crusher, splitting machine, and mountain machine, hydraulic splitting machine, stone splitting machine. The big split or hydraulic rock splitter is directly mounted on the excavator and uses the excavator hydraulic pressure as power. The principle is that after the output pressure of the excavator is increased by the supercharger, the driving cylinder generates a huge driving force, and then the splitting force of the strong force is generated after the mechanical amplification, so that the stone is split according to the predetermined surface.

In stone mining, air bag splitting adopts gas pressure as the driving force, and the air bag is inserted into the gap of the waste material to separate the waste material. This mining process is a new mining process, the operation is simple, the operator is safer, and it is worth vigorously promoting in the stone mining process.

Mine waste materials should be equipped with complete labor protection articles when splitting. Summer operation should also be prepared to prevent heat stroke cooling drugs, to prevent people from heat stroke.

When drilling with an air hammer, pay attention to the stone debris and gravel collapse to the eyes and some parts of the body, causing harm to the human body. When standing on the cut block or rock mass, the surface of the rock mass should be checked first to judge the stability of the cut block or rock mass before working on it. The unstable, cracked and severely weathered blocks or rock mass should be safeguarded before operation. During the splitting operation, pay attention to the surrounding area, especially the slope and mountain above the working area, and always pay attention to whether there is a stone fall above the working area and lead to a safety accident.

If the excavator is used to crack the stone and rock mass, the operator must be the person who holds the working certificate, and the unlicensed person is strictly prohibited to operate; Before the excavator operation, the road surface in the working area should be sorted out, the obstacles affecting the excavator operation should be removed, and the road surface in the excavator operation area should be reinforced. The stability of the excavator should be ensured during the operation to prevent the splitting operation from being affected by the instability of the excavator. When the excavator splits, non-operators are prohibited to enter the working area; When the split block or rock mass is separated from the main body, pay attention to the dumping direction to prevent injury when the split material is dumped.

When the artificial wedge splits, the firm situation between the hammer and the handle should be checked frequently to prevent the hammer head from flying out and the hammer handle from breaking; Often check the integrity of the wedge to prevent the wedge from breaking and flying out of injury; Replace the wedge when it is not sharp.
