Applied Technology with Application of Power Ultrasound for Preventing Gas Disaster in Coal Mines

Abstract:

The mechanism of power ultrasound for preventing gas disaster in coal mines and its application prospect are introduced in this paper. The research results show that, the main mechanisms of power ultrasound on coal are the additional stress shock wave and jet on the crack tips. The permeability of infusion holes around the coal increases, expanding the radius of water infusion moist. The moisture content of the coal body increases and good effect of power ultrasound for preventing gas disaster in coal mines can be obtained. The technology of power ultrasound on gas disaster in coal mines has a good application prospect.
