And a mine can be dug underground in the mining process, and the mine is also an operation surface for mining operation. During the mining process, a large amount of dust is generated, which causes great harm to the bodies of mining personnel and also causes safety hazards inside the mine. Since the dust amount reaches a certain concentration, which would cause the risk of explosion.
At present, the mine can be ventilated to discharge dust in the mine, but if the mine is far away from the ground, the mine is deep, a large amount of dust cannot be discharged in time, and the safety of mining operation is influenced. And the mining area adopts sprayed water for dust fall, and dust can be fallen through water drops. However, water spraying cannot be conducted in an unregulated mode, so that excessive water spraying is caused, the water quantity in a mine is increased, and further hidden danger is brought. Therefore, the dust situation in the mine needs to be known in real time, the water spraying is controlled to perform dust fall when the dust falls, and the water spraying is controlled to stop after a certain amount.
