Abstract:
In order to do dust prevention work better, we adopt rapid tunneling system that takes driving and anchor machine, crusher, astride type reversed loader, belt conveyor as the main equipment, and integrates the wet dust removal fan that can be directly connected to the original driving and anchor machine. On the basis of the ventilation system parameters calculation, a mixed dust collection dust removal system for rapid heading face is formed through the selection of ventilation equipment. The system not only greatly reduces the concentration of coal dust in rapid heading face, even dust-laying rate of total dust concentration reaches to 29.97%, but also increases mechanization efficiency and reduces labor intensity.
