| Abstract: | Based on the theory of hydraulic
mechanics and air-jet technology, the principle and method of isolating the respiring dust at the
driver's position with technology of the air curtain has analyzed and researched in the
comprehensive mechanized working face. The air curtain established a immateriality and
transparent barrier between the driver of the machine and the coal wall, and stopped the dust
diffusing to the driver's position during the process of coal-cutting. The application effects were
good in producing site, and the average efficiency of isolating dust was 82.34%. Therefore, the
air curtain technology described to the paper has a better application value in the
comprehensive mechanized coal working face and a wide foreground to popularize in the
mining industry. 2figs., 2tabs, 5refs. |
