(2) When the cable is caused by a fault, the power of the faulty cable should be cut off immediately, and the firefighting should be extinguished without any chance. When the fire spreads too quickly and cannot be extinguished immediately, the personnel of the nearby mining (digging) area and the team should be immediately notified to evacuate the dangerous area quickly, and report to the mine leader to further take fire-fighting measures or fire according to the mine disaster plan. (3) When the ground test method is used to test the failure of the downhole armored cable, the wind flow in the inlet tunnel may be less than 1%. For the underground mining (digging) working face, the gas concentration used must be in the ordinary type of portable electrical measuring instrument to determine the cable fault, the gas inspector must check the gas content of the site, only the gas concentration is below 1%. be usable. (4) When the downhole rubber cable fails, it should be analyzed and judged according to the fault phenomenon to determine the fault type and fault point. When troubleshooting, the faulty cable must be completely separated from other cables for testing and processing. (5) When the switch connecting the cable trips, the maintenance electrician shall be responsible for finding out the cause, and the gas inspector shall check the gas concentration of the section where the faulty cable is located, and the detection shall be carried out when the concentration is below 1%. For mines with coal (rock) and gas outburst and faulty cables in the gas injection area, it is strictly forbidden to use the test power transmission method to judge the fault and find the cable fault point.

Technical treatment when coal mine underground cable fails
(1) After the cable fault occurs, firstly, according to the phenomenon and state of the fault, the fault type is correctly judged, and the mine dispatching and electromechanical authorities are reported in time, and the relevant personnel are quickly processed.
