          Safety technical measures for power monitoring communication optical cable

          發布時間:2022-06-06 09:10:14人氣:

          Before the construction of mining optical cables, the construction personnel shall wear raincoats, safety belts and walkie talkies. After placing the optical cable in the central substation, the construction personnel put it back into the wellhead. During the operation, the construction leader on the cage contacts the wellhead construction leader with the interphone. Each time he arrives at the wellhead cable card, he shall contact the wellhead to stop, and then fix the optical cable on the cable card until the optical cable is fixed on the pipeline.




          The safety technical measures for power monitoring communication optical cables are laid in the auxiliary shaft and underground main roadway.




          According to the requirements of the mine, the monitoring device is installed for the high-voltage switch of the underground substation, and the special optical cable is re laid twice. In order to ensure the construction quality and safety of optical cable laying, the safety technical measures are formulated.




          1、 Construction time: scheduling meeting plan.




          2、 Construction organization and location.




          General principal: safety principal:




          Construction principal: technical principal:




          It takes two times to lay the optical cable in the shaft. The first time, the optical cable is laid in the shaft and simply fixed. The second time, it is permanently fixed with a cable clamp.

          It takes two times to lay the optical cable in the shaft. The first time, the optical cable is laid in the shaft and simply fixed. The second time, it is permanently fixed with a cable clamp.




          3、 Construction method.




          Due to the light weight of cables and optical cables, it is decided to adopt the manual method to lay them in the auxiliary shaft and roadway. The specific methods are as follows:




          1. put the prepared optical cable on the rope support, on the west side of the auxiliary wellhead, and put the required optical cable into the wall hole on the west side of the wellhead.




          2. before construction, construction personnel shall wear raincoats, safety belts and walkie talkies.




          3. stop the small tank at the wellhead (the winch room depth display shows -10m). The construction personnel shall select and stand on the top of the small tank, fasten the safety belt and fasten it at a reliable place. The construction personnel shall use optical cables and interphones to contact the wellhead construction personnel. The wellhead construction personnel shall contact the auxiliary shaft elevator driver. The running speed of the small tank is 0.3m/s. During the operation, two construction personnel are responsible for setting out, and one construction personnel is responsible for using walkie talkie to contact parking and sending.

          4. during lowering, the construction personnel shall pay off properly according to the lowering speed, and simply stabilize the optical cable every 20m to ensure that the cage operation and optical cable lowering are not affected. After being lowered to the auxiliary shaft bottom pipeline, the construction personnel will place the optical cable in the central substation through the pipeline, leaving enough margin.




          5. after placing the optical cable in the central substation, the construction personnel shall put it back into the wellhead. During lowering, the running speed of the cage is 0.3m/s. During the operation, the construction leader on the cage contacts the wellhead construction leader with the interphone. Each time he arrives at the wellhead cable card, he shall contact the wellhead to stop, and then fix the optical cable on the cable card until the optical cable is fixed on the pipeline.




          6. after the cable in the shaft is laid, the optical cable shall be arranged along the pipeline, connected with the central substation along the substation cable trench, and connected with the high-voltage switch.




          7. after the central substation is completed, optical cables shall be laid from the central substation to the main lane. See the attached drawings for the specific construction sequence.




          3、 Safety technical measures.




          1. before construction, the construction director shall organize all construction personnel to carefully study the construction scheme, understand the construction methods and safety precautions, and establish a solid safety awareness.




          2. the construction personnel shall keep the idea of safety first, do a good job in safety work, obey the command, and prohibit three violations.




          3. before construction, the person in charge of the site shall clarify the responsibilities of all construction personnel and achieve full-time and unified command.




          4. fireworks are strictly prohibited within 20 meters around the auxiliary wellhead, and operators are strictly prohibited at the auxiliary wellhead.




          Smoking in the room, using mobile phones.




          5. operators must wear underground work clothes, safety helmets and other labor protection articles, tighten their cuffs, concentrate and operate carefully.




          6. construction personnel and other climbing operators above the cage must wear safety belts. Check carefully before use, and use only after there is no problem. The safety belt must be fastened in a firm and reliable position. When solving the safety belt, secondary confirmation shall be carried out to prevent wrong solution.




          7. during operation, the spanner and other tools used shall be tied with rope and put on the wrist to prevent falling into the shaft.




          8. Before construction, check the local signals and interphones, solve or replace the problems in time, and carry out construction after confirmation.




          Mine optical cable




          The signals sent by construction personnel during construction shall be correct and clear. The hoist driver shall strictly implement the one person operation and one monitoring system, hear the signal clearly and operate cautiously.




          The paying off personnel shall pay off properly according to the lowering speed, and it is strictly prohibited that the optical cable sag is too large without sag.

          施工人員在施工過程中發送的信號應正確、清晰。提升機司機要嚴格執行一人操作、一監護制度,聽清信號,謹慎操作。

          下放線人員應根據下降速度適當放線,嚴禁光纜垂度過大,無垂度。

          11.施工前,應制定罐籠上的施工負責人和井口的施工負責人,施工負責人應攜帶對講機,確保只有施工負責人發出的指示才能駕駛。提升時,確保提升機運行速度控制在0.3m/s。

          12.井口施工負責人接到施工命令后,向副井絞車室發送信號。絞車運行緩慢。罐籠進入井筒后,罐籠上的施工負責人與井口施工負責人聯系,井口負責人直接向絞車室發送信號,井口不再發送信號。

          11. before construction, the construction leader on the cage and the construction leader at the wellhead shall be established. The construction leader shall carry a walkie talkie to ensure that only the instructions issued by the construction leader can be driven. During lifting, ensure that the operating speed of the hoist is controlled at 0.3m/s.




          12. after receiving the construction order, the head of wellhead construction shall send a signal to the auxiliary shaft winch room. The winch operates slowly. After the cage enters the shaft, the person in charge of construction on the cage contacts with the person in charge of wellhead construction. The person in charge of wellhead directly sends a signal to the winch room, and the signal will not be sent to the wellhead.

          13. during the construction of East Rail main roadway and upper warehouse inclined roadway, it is strictly prohibited to lift the endless rope winch.




          When transporting with belt, the construction personnel shall fasten the safety belt at a reliable place and arrange the construction personnel to monitor.




          14. when laying optical cables, the optical cables shall be protected to prevent the skin of optical cables from cracking during construction.
