Mineral dust refers to fine particles of ore or rock produced during the mining process. The dust of the mine is very dangerous to the human body (the dust with a diameter of 5μm or less is the most harmful to the human body), especially when the mine dust floating in the mine air contains free silica (SiO 2 ) exceeds a certain value, the body of the miner it will cause a great threat to health, the Ministry of metallurgical industry "dust trial ventilation provisions" provides that: "If the content of SiO 2 dust free in more than 10%, dust concentration should not exceed 2mg / m 3; if the 10% or less, no more than 10mg/m 3 , if it exceeds this standard, it is very harmful to the human body." In the underground mining process, a large amount of dust is generated during rock drilling, blasting and mining, so measures must be taken. China's dust-proof measures in the long-term struggle with the mining dust summed up the "wind, water, secret, protection, leather, management, teaching, inspection" eight-word measures. which is: Wind-ventilation dust removal; water-wet operation; dense-closed dust source; protection-personal protection; Leather - technological innovation; management - scientific management; teaching - publicity and education; inspection - regular inspection. The above eight-character measures are effective methods. Many mines have long adhered to this measure and achieved good results.
