Safety technical measures for coal mine shipment materials

1. When a large piece is on the train, it must be supervised by a manager or above, and the mechanical loading method should be used as much as possible. When the machine is loaded, all personnel must stand in a safe and reliable place to avoid accidents and cannot use machinery. Consider the manual lifting of the loading.

2. Personnel must carry enough personnel to get on the train. The average carrying capacity must not exceed 30Kg/person. The operator's movements are coordinated and coordinated by the special person, so that they can be the same, falling, and falling.

3. When loading the vehicle, in order to make the center of gravity of the machine and the center of gravity of the flatbed coincide, it is necessary to put a wooden board or road wood of not less than 40mm thick on the flatbed to prevent the sliding of the machine, but it must not be overloaded, super wide or super high.

4, conducted by experienced personnel loading and bundled work, objects and flower column flatbed fixed connection screws Φ18.5mm wire rope and tied with the M20, and not less than 4, then 8, 4 share lead wire , before and after the two bundles of loading and loading, you must tighten the strength to ensure that the wire is evenly stressed.

5. When binding, the exposed mating surface of each machine part, the protruding corners and the precision parts of the shaft head should be packaged and protected to prevent collision damage or accident during transportation.

6. When binding the deformable parts, measures must be taken to prevent them from deforming. The sliding parts on the equipment should be fixed to prevent sliding.

7. The inspection by the squad leader can be submitted to the transport team for decentralization.

(2) Lifting safety technical measures:

1. When lifting large pieces, it must be directed by a special person (squad leader or foreman), and the designated person should check the mechanical rigging and tool tools. It is strictly forbidden to use.

2. When lifting equipment with chain (chain hoist), the lifting capacity of lifting tools such as chain, hook and rope head must be more than 2 times the weight of the lifting object.

3. For lifting large parts, it is necessary to use steel wire rope or bundle large parts with Φ18×64mm scraper chain. It is strictly forbidden to bundle the reverse chain directly on the large piece. The diameter of the steel wire rope buckle should not be less than Φ12.5mm.

4. During the lifting process, within 2 meters around the hanging object, except for the lifting operator, other people are strictly prohibited from working or staying. The lifting personnel should stand at the opposite position from the falling of the heavy object, at least 0.5m below the edge of the heavy object.

5. It is strictly forbidden to lift by overload (that is, the vertical lifting force of each anchor is 2.5T)

6. When lifting, you should first try to hang 100-200mm, and then lift it after checking without problems.

7. When pulling the small chain, the hands should be evenly applied, not too fast and too fast; when lifting heavy objects need to be suspended, the small chain must be tied to the big chain.

8. It is strictly forbidden to push and pull the hanging objects by hand or foot during lifting.

9. When lifting, a special person should be set to observe the roof of the roadway, check the safety of the lifting parts and the connecting parts, and immediately stop lifting when the problem is found, and then continue the operation after handling.

10. Lifting and lifting in the lifting, stable and stable operation, it is strictly forbidden to yank hard.

11. The lifting personnel must follow the instructions of the commanding personnel and operate them properly.

12. When heavy objects are lifted, work should not be stopped in the middle; when the equipment is in place or stopped in the middle, it should be placed firmly; for equipment with high center of gravity, the equipment should be removed after anti-shake or dumping measures.

(3) Safety technical measures for lifting materials

When transporting materials, in addition to complying with the relevant provisions of item (1), the following provisions must also be observed:

1. When manually transporting large pieces, first check the support conditions of the walking route. If there are hidden dangers, they must be removed in time before they can be transported.

2. Check all obstacles on the walking route and remove them before lifting.

3. The squad leader and the cadre of the class must personally check the binding condition of the materials to be transported. It must be firm and reliable, and confirm that there are no hidden dangers and no danger.

4, the transport personnel must work together, focus on energy, must be shoulder, the same, with the same, is strictly prohibited to throw.

5, such as a single person carrying heavy objects, the squad leader, the cadre of the class must assign a special person, indeed a single person can not be completed, must be completed by many people, so as to avoid accidents.

6. Before transporting large parts underground, it is necessary to carry out a comprehensive inspection of the track, winch brake device, wire rope, hook head, signal system and safety facilities. Before using the winch or pulley to haul large parts, the load on the winch and the load on the wire rope are required. The capacity and the rated load of the pulley are checked to ensure correct operation.

7. When carrying large shipments, the squad leader and the cadre of the class must be directed by the person on site.

8. When loading and unloading and lifting the rails, it is necessary to match the personnel (at least 10 people) and have the command of the person in charge of the site. When lifting the rails, it must be coordinated before and after the lifting, and should be thrown together to prevent injury.

9, when decentralized rail, firmly tied with a rope, and a # 8 iron wire connecting bolt hole of the first channel together, to prevent slippage during transport inclined,
