First, the red line of safety management
1, the mine failed to implement the party and government decision-making and deployment, and the site management was not in place, which caused great security risks.
2, procedures and measures do not conform to the relevant provisions, out of touch with the scene, causing a big accident.
3, leading cadres at all levels with (with) the class did not strictly implement the provisions of "before work, after work, in class, in place, in place", resulting in a major accident.
4. Do not change the support parameters to reduce the support strength; Cut the anchor cable in violation of regulations; Arbitrarily increase the cycle progress of tunneling faces; When the surrounding rock (coal) of geological structure roadway changes, support measures are not taken in time.
5, do not implement the mine shall be ordered to suspend production for rectification, to continue production operations.
6, unplanned, no measures through the roadway.
7, not according to the provisions of the water prevention and control measures to implement the "doubt must be explored, first explore before digging" or "first dig must be explored, first explore before digging".
8. The infrared locking, life detector, cable emergency stop, belt conveyor and monkey car cable emergency stop at the coal mining face did not work, and relevant measures were not taken to arrange for continued operation.
9, transportation roadway closed management, mine inspection found three times a year related safety measures are not implemented.
10, the safety facilities in the transportation lane are not complete and intact, and the rectification is not timely, so it continues to run.
1 1. Dismantling the installation project without organization acceptance.
12, due to subjective factors, the main fan stopped for more than 30 minutes.
13, the future on-site command of cadres at all levels of gas extraction, and there is a "gust of wind" or no power outage in the gas extraction flow area; At the same time, more than two working faces in the same mining area discharge gas.
14, arrange unlicensed personnel to work.
15. During the inspection by the superior organization, more than 3 people were found to be on duty without a license at a time.
Second, the red line of safe operation
1, the gas concentration at the mixed airflow caused by gas discharge reaches or exceeds1.5%; Open the fence at will or close it to enter a dead end; Failing to organize evacuation or refusing to evacuate in time after the wind stops in the mining face; The mining face with gas overrun fails to stop operation immediately or fails to take effective control measures to resume production; Opening two dampers at the same time will cause short circuit of air flow.
2. Failing to take outburst prevention measures as required or failing to implement them in place; Gas inspectors and outburst prevention personnel practise fraud, falsely report detection data or gas inspectors miss detection and leave their posts without permission when conducting gas inspection and outburst prevention index detection.
