Mine equipment operation safety risk points and prevention and control

The safety risks of mining equipment operation are more and more complex, and the safety accidents caused by the involved aspects are more, and the accident one and occurs lightly will hurt the legs and feet, and the heavy will die, therefore, the safety risk point of mining equipment operation is the top priority of the safety management of stone open-pit mines.

(1) Safety risks and prevention and control of mine locust crane operation

① Safety risks and prevention and control of rod crane installation. Rod crane is used to lift stone overweight equipment, which is similar to gantry crane, belongs to special equipment. Therefore, the installation of this equipment must be completed by professionals from the equipment manufacturer. The installation of non-professional personnel will cause safety accidents, and the installation of locust rod crane may have serious security risks. Therefore, stone production enterprises to buy rod crane to choose qualified enterprise products, installation check whether the installation personnel have qualifications. Only from these two aspects can we reduce the safety risks brought by the cotton pole crane.

Mast installation should be made in advance of the installation plan, and through the rod manufacturers, stone mining enterprises audit and implementation. When the mast crane is installed, the geological and topographic analysis of the installation position must be carried out carefully. Choose a hard surface; The terrain selection of wind is relatively small, to avoid the occurrence of rain floods, landslides, rod crane installation should be cleaned up affecting the installation and debugging of obstacles. Non-equipment installation personnel are strictly prohibited. The stone mining enterprise where the olive rod crane is installed should have special personnel to coordinate the installation of water, electricity, gas and other installation things.

② Safety risk prevention and control during mast crane operation. Stone mining enterprises should formulate strict "safety regulations for crane operation", operators carefully according to the "mast crane operation safety regulations" operation, to prevent safety accidents, crane operators should be professionally trained and hold a job license personnel, strictly prohibited unlicensed personnel on the post, rod crane overweight lifting, speeding operation, illegal operation is the biggest safety hazard when mast crane operation. The safety personnel of stone mining enterprises must strengthen strict law enforcement in this respect, and the violators will be prosecuted and severely punished.

(3) Risk prevention and control during maintenance of mast crane. When entering the mast operation area, the pusher and repair personnel should comply with the requirements of the mast crane Operation Safety Regulations and wear labor protection articles. In addition to the maintenance of daily operators, stone mining enterprises must designate special equipment maintenance personnel to repair and maintain the mast crane on a monthly basis. Maintenance personnel shall formulate maintenance plans and carry out maintenance after approval by relevant technical departments. Mast crane maintenance operations must be operated by two maintenance personnel at the same time, and two people must cooperate closely: maintenance personnel must be equipped with safety belts if they need to climb high: operation is strictly prohibited in strong wind, heavy rain and severe frost weather.

(2) Mining drilling machine operation safety risk points and prevention and control

Mining drilling machine is a very common production equipment in stone mining, including gas leg, drill and so on. The operation of these drilling RIGS should be carried out by skilled staff, otherwise it will easily lead to safety risks.

① Risk of injury caused by rock fall in the working area. Many places in the stone mining area are close to the slope, the mountain, these places often appear rock fall, stone rolling phenomenon, if the operation is not found in time, may cause injury to the staff in the operation area, accidents.

② Risk of injury caused by drill pipe fracture. Due to the poor quality of drill pipe in the process of mining and drilling, drill pipe fracture will occur in the wild honey operation of rig operators. If the workers do not avoid in time, the fracture of the drill pipe can cause injury to people.

(3) Occupational disease risk, the dust generated in the drilling process, if the operator does not take dust prevention measures, a long time may get pneumoconiosis, which is a great harm to people's occupational disease; Drillers should wear earplugs during operation to prevent damage to their ears caused by drilling sound.

④ Risk of injury when drill and rock just fall off. In the process of drilling and de-drilling, the cuttings brought out by the drill bit and drilling hole fall and injure people.

(3) Mine disk saw operation safety risk points and prevention and control

The circular saw is widely used in stone mining and is an important equipment for stone mining, especially for granite mining. If the lack of awareness of safety risk prevention during the operation of the mine disk saw, it is easy to lead to safety production accidents, Figure 5 is the disk saw for granite, Figure 5 is the disk saw for granite.
