How to avoid the risk of open-pit mining, 24 prevention and control points to ensure production safety

(2) Vehicle sinking accident

Because the stone open-pit mine road is not strictly built in accordance with the mine road design specifications, the road is not compacting, in case of bad weather, the road softens and sinks, when the vehicle is driving on the softened road, there will be a sinking phenomenon, resulting in vehicle driving map difficult, and even accidents.

(3) Vehicle skid

The slope of the mine road is steep, the road slope is large, and the road is slippery, and the skid of the mine vehicle is common. If it is serious, it will even cause the vehicle to tip over and cause a major safety accident. Figure 4 is a granite mine, and the mining surface forms an obvious steep slope compared with the highway, which is easy for the vehicle to slip.

(4) Vehicle breakdown on the road

Vehicle failure, vehicle overload leads to trapped in the road accident. Although the vehicle breaking down on the road does not lead to serious safety accidents, it will seriously affect the normal progress of production and cannot be underestimated.

(5) Road collapse

Due to the large investment in the construction of roads in open-pit stone mines, some mine owners will not invest a lot of money in the road construction that does not produce a return on the principle of saving on the province, resulting in mine roads not strictly in accordance with the requirements of the design Code for open-pit mine road construction, resulting in road landslides seriously affecting mine production.

3. Prevention and control of road safety risk points in open-pit mines

(1) Risk prevention and control of vehicle rollover accidents

The prevention and control of vehicle accident risk in stone open-pit mines should pay attention to the following aspects: road construction should be carried out in strict accordance with the "Code for Road Design in open-pit Mines", and the construction quality of road construction should be well paid to reduce the accident risk of vehicle rollover caused by poor road construction quality.

Mine road conditions should be checked regularly, timely detection of road safety hazards, strengthen the management of vehicle drivers, and prohibit unlicensed driving. Strengthen the management of vehicle personnel, strictly prohibit illegal driving, and improve the sense of responsibility of drivers. Vehicles and quarrying operations are strictly prohibited in bad weather.

Risk warning signs should be set up in sections with large cliffs and drops to remind vehicle drivers to drive safely, and firm safety protection facilities should be set up to prevent the further deterioration of safety accidents when vehicles roll over.

(2) Risk prevention and control of vehicle sinking accidents

Vehicle sinking accidents are mostly caused by soft road surface and roadbed collapse. The key to control this kind of accident risk is to strengthen the control of road pavement construction quality. The road construction should be carried out in strict accordance with the "Code for Road Design of Open Pit Mines" to improve the construction quality of mine roads. Regular inspection of mine road conditions, timely detection of road safety hazards.

Strictly control vehicle overloading and speeding. Overload is a common phenomenon in stone mines. Mining enterprises in order to produce more ore, truck drivers in order to DORA goods to make money, regardless of safety risks. In order to curb the risk of vehicle sinking, subjective management in this respect should be strengthened, and the behavior of overloading and speeding should be severely cracked down on.

(3) Prevention and control of vehicle skid risk

The prevention and control of vehicle skid risk should be strengthened from the following points:

Road construction is carried out in strict accordance with the "Code for Road Design in Open Pit Mines", and the construction quality of road construction is paid attention to, especially the quality of road pavement. Mine road conditions should be inspected regularly, and mine roads should be regularly maintained, repaired and compacted. Eliminate the safety hazard of road slip. Vehicles and mining operations are strictly prohibited in inclement weather such as snow, ice and heavy rain. Anti-skid measures should be taken when work is necessary

(4) Risk prevention and control of vehicle breakdown

The risk of vehicle throwing wrong on the road is mostly due to vehicle failure. The focus of risk control is to strengthen vehicle inspection and strengthen daily maintenance and repair.

Strengthen the maintenance and inspection of roads, and clean up stones that are easy to puncture tires. It is strictly prohibited to overload and control the load of the vehicle.

(5) Prevention and control of road collapse risk

The risk of road collapse is mostly caused by major problems in road quality, strengthen the quality of road construction, daily inspection of roads, timely discovery of road safety hazards, and timely repair.

Road subgrade and road slope are the key places of road collapse risk management. Mine management personnel should establish technical data file management for roadbed and slope with wall risk, and have technical measures and emergency plans to prevent road collapse.
