Mining anti outburst air door/coal mine pneumatic anti gas outburst air door

Mining anti outburst air door is a safety protection facility set up when the protruding coal seam is exposed in the mine roadway and mining operations are carried out in the protruding coal seam; When disasters such as gas outbursts occur, it can quickly shut down, isolate the disaster area, prevent the spread of harmful gases, and avoid the expansion of the disaster range.

Mining anti outburst air door is another name for the automatic air door for preventing gas outburst in coal mines. A set of coal mine anti outburst air doors generally includes 4 channels, namely 2 forward air doors and 2 reverse air doors. The remote intelligent anti outburst air door control system is associated with multiple sensors. Once the gas exceeds the standard, the safety door will automatically close and sound an alarm.

At least 2 sturdy and reliable mining anti outburst air doors must be installed on the air inlet side of the coal mining excavation face in the coal seam protruding roadway, coal roadway, and semi coal rock roadway. The distance between the air doors should not be less than 4m, and the distance from the return airway of the working face should not be less than 10m. The closest distance to the working face should generally not be less than 70m.

The automatic air door for preventing gas outburst in coal mines is managed by hanging tags, unified numbering, and setting up management boards; Clearly define the responsible unit and person for each shift inspection, and have tile inspectors conduct inspections every shift; After the completion of the construction of the mine pneumatic anti surge air door, the communication and defense department shall organize acceptance and set up a ledger for management.
