Second, the measures Note: In accordance with Article 462 edition 2016 "coal mine safety regulations": "do need to tilt the roadway in the mechanical lift of the air intake (not including the conveyor, down) when the laying of power cables, should have reliable protection The measures are approved by the chief engineer of the mine. "This safety measure is specially formulated to ensure the safety of the person and the cable when laying the power cable in the inclined shaft of the mine. Third, time: 2016 Fourth, location: underground wind inclined shaft V. Construction organization: 1. Construction leader: ***** 2. Security leader: ***** 3. Technical leader: ***** 4. Construction workers: ***** Sixth, construction methods and safety measures: 1. When laying the power cable in the inclined shaft of the mechanically reinforced inclined shaft, the responsible person of the organic electric professional technical department must be responsible for the on-site command to ensure the smooth construction. 2. Before laying the cable, the person in charge of the construction should check the condition of the roadway in advance to ensure that the roadway support is good. When the quality of the roadway support is not good, it should be reported to the dispatching room and arranged for the personnel to handle before laying. 3. Before laying the cable, the cable should be transported to the inclined shaft of the mechanical lift by the mine car, and then laid by the shoulders of the personnel. 4. During the process of laying the cable, all the participants should wear helmets and gloves, dress neatly, concentrate, listen to the command, follow the same steps, before and after the call, before and after. 5. In order to prevent cable slippage and cable discount and wear, the distance between the shoulder blades of the personnel shall not exceed 10m. All personnel are prohibited from flickering and slowing during the walking process. It is strictly forbidden to carry the cable to the ground. 6. The professional responsible for laying the cable should pay attention to the condition of laying the cable personnel at all times, promptly remind the laying personnel of the walking speed and replace the position of the shoulder, and eliminate the phenomenon of leaving the middle. 7. In the corner of the roadway, you must set up a special person to command, all personnel should slow down and stand on the outside of the cable to prevent being crushed by the cable. 8. When laying cables in the inclined shafts of the mechanically reinforced inlets, it is strictly forbidden to drive pedestrians. All personnel should pull the distance and apply even force. During the laying process, it is strictly forbidden for personnel to lower the cable from the shoulder to prevent the cable from slipping on the slope. 9. All involved in the laying of the staff must follow the unified arrangement of the responsible person. When laying the cable, all personnel must shoulder and shoulder at the same time. 10. During the whole construction process, relevant responsible persons should coordinate and direct the command. The safety person in charge is responsible for the safety work, and carefully checks each construction process to ensure construction safety. 11. The person in charge of construction shall organize all construction personnel to study and discuss the construction measures, and everyone may sign up to participate in the construction. Seven, cable hanging standards and requirements: 1. Cables should be provided with no joints in the inclined shafts. When joints are required, they must be connected with the four wires that meet the requirements, and the four-way suspension is firm. The cables have appropriate remainders and must not be stressed. 2. The protective device of the feeder switch short circuit, overload and leak detection of the line in the inclined shaft of the mechanically reinforced inclined shaft (excluding the conveyor and the downhill) should be complete, accurate and sensitive. 3, to ensure the quality of the cable laying, cable applications dedicated cable hooks, clamps or other clamping means for laying the cable clamping device should be able to withstand the weight, and can not damage the cable, prohibited the use of iron wire, nylon rope hanging cable . 4. The roadway support of the inclined shaft of the power cable must be in good condition and regularly checked and maintained. The distance between the suspension points of the cable should not exceed 1 m in the inclined shaft. The suspended cable should have proper sag and can be affected. Free fall when force. 5. The power cables laid in the inclined shafts of the mechanically reinforced inlets shall be designated to carry out regular inspection and maintenance of their joints, insulation resistance, local temperature rise and suspension of cables. 6. When there are handrails for auxiliary personnel walking in the inclined shaft, the cable should be hung above the handrail to prevent the cable from being pulled when the person walks. 7. The suspension height of the cable shall not be less than 1.5m, and the cable shall be protected from impact when the broken rope sports car or the mine car is dropped. 8. The cable must not be hung on the air duct or water pipe, and must not be exposed to water. It is strictly forbidden to hang any objects on the cable. When the cable is laid on the same side of the roadway as the air duct and water pipe, it must be laid above the pipe and kept at a distance of more than 0.3m. 9. In order to prevent the cable from slipping, the cable laid in the inclined shaft should be fixed at a suitable position with a butterfly clip every 50m. 10. The power cables laid in the inclined shafts of the air inlets shall be designated to clean the coal dust on the wells and cables regularly.
Lamination of various choices: plain gold, plain white, transparent,
