When it is found that there is coal spontaneous combustion on the surface of the coal pile, the method of spraying cooling or digging ditch watering can be adopted.
If the temperature of the coal pile is found to be high, a bulldozer can be used to push away a layer for heat dissipation.
The pressure tube is inserted into the spontaneous combustion part of coal pile to cool the coal pile, which can effectively control the spontaneous combustion of coal pile.
For small piles of coal, the outermost layer of the spontaneous combustion part can be pushed away to expose the spontaneous combustion part for cooling.
For the coal pile with high temperature, the forklift can be used to reverse the pile to reduce the temperature of the coal pile and delay the spontaneous combustion of coal.
The coal in the source area will be dug out, spread out, exposed to the air to cool the heat, or the coal in the source area will be rolled.
When coal mines are used for cooling, measures must be taken to prevent the spread of open flames.
There is a certain amount of slag around, rescue workers also need to take protective measures.
