1. It is necessary to carefully check the roof of the transportation line, the situation of the coal gang, and find hidden dangers in time. The shed beam used must be drilled with a column or mast to clean up the floating coal and debris in the roadway.
2, the working surface of the work surface should be put the coal to help the column, back good, such as the top plate is not good to maintain small materials, the bracket must be good.
3, slip on the clean, so that it is unimpeded.
4, check the use of equipment in good condition, especially the sound and light signals should be sensitive, complete and reliable. Operators must be certified to work and concentrate.
5. Set up the person in charge of sending and receiving electricity.
Second, the transportation of components
The transportation of components is strictly carried out in accordance with the "Safety Technical Measures for the Transportation of Work Faces and Return Airways".
Third, lifting
The lifting objects are strictly implemented in accordance with the "Safety Technical Measures for Object Lifting".
Fourth, dismantling, overhaul and installation
1. It is strictly forbidden to carry out electricity operation for equipment such as repairing or replacing the motor, and carefully implement the system of power-off and power-off.
2. Dismantle and install in order. It is strictly forbidden to extend any part of the body into the butt joint of the part.
3. When replacing, all personnel must obey the command, and the person in charge is responsible for safety.
4. If there are any parts that cannot be removed, it is strictly forbidden to use the gun.
Fifth, deal with work slippery, broken chain accidents.
1. Before handling the slippery way and breaking the chain, the switch control handle must be hit to zero position, so that the starter is in a power outage state, and the power-off card of “someone works, no power transmission†is hung to ensure that others cannot be mistakenly sent. Electricity.
2. Carefully check whether the roof and coal wall of the sling are safe and reliable. It is necessary to select the roof to be stable, and there is no place to help the dangerous place to hang the slipper. If the top plate is broken, it is strictly forbidden to carry out the downswing.
3. When the shovel is lifted to the required height, it must be supported by a special person with a road or a column cap to ensure that it is firm and reliable. The road used must not exceed two floors. The cap "well" type support pad shall not exceed 3 layers at most, and the spacing of the support pads shall not exceed 3 meters. After the support, it shall be slowly slid. This work is carried out under the supervision of a dedicated person, from lifting, supporting, to sliding. It is strictly forbidden to extend any part of the body under the slip when laying the material. 4. After the slipper confirms that the support pad is in good condition, the large chain at the drop can be pulled out with the tool, the scraper is removed, the horseshoe screw is put on, and the big chain is put on the road. When dragging the chain or removing the scraper, it is strictly forbidden to extend any part of the body into the bottom of the chute.
5. Before opening the shovel, clean up the debris on the top and bottom of the chute, and do not mix the chain. Personnel should be sent to a safe place before they can send electricity. Use the signal to contact the jog, then open the big chain to the upper slot and scrape the scraper.
Sixth, after the completion of the test
Before the test, a thorough inspection is required. Check the oil level on the gear unit and clean it. After confirming the error, you can send the power to test the vehicle. After no problem, remove the wood from the support slip, and then carry out the load test, and the rear can be closed.
7. The following provisions shall be imposed for the power transmission:
1. The person in charge of power transmission will power off and lock the switch, and will be sent to the special person for care (stopping the operator).
2. The person in charge of the power transmission can only start work after arriving at the work place.
3. The operator who stops the power transmission only obeys the power-off work instruction of the person in charge of the power transmission.
4. The person in charge of power transmission and delivery must send a power-off work order to the power-sending operator in writing, and it is strictly forbidden to call and stop sending power.
5. Other strict implementation of the Mine Regulations on Underground Power Transmission and Management.
