A kind of coal-gas recovering conveyance conduit method of controlling security, comprises the following steps：
Step one：Venting of dust explosion valve events, coal-gas recovering conveyance conduit venting of dust explosion, release energy；
Step 2：Position detecting switch on explosion venting valve detects explosion venting valve valve position detection signal, and feeds back to PLC controls
System；
Step 3：PLC control system control nitrogen gas control valve is opened, and quickly the inflated with nitrogen into gas pipeline, is blocked
Danger enters gas chamber, while glasses valve is cut off in quick closedown；
Step 4：PLC control system detect cut-out glasses valve completely close after, close nitrogen gas control valve, stop nitrogen charging；
Step 5：System recovers normal rear open and cuts off glasses valve.
The invention has the advantages that：Solve the safety that coal-gas recovering conveyance conduit is present during coal-gas recovering
Problem, the risk that oxygen explodes may be mixed into for gas pipeline presence during coal-gas recovering, in its pipe
Explosion venting valve is installed on road, while signal detection switch is equipped with, after occurring venting of dust explosion, quick nitrogen charging and fast shut-off into pipeline
Valve, blocks danger to enter gas chamber, prevention accident further expands.
