| Abstract: | Based on the detailed analysis of the current dust-proof situation of the fast-tunneling woking face and the problems existing in the application of the long pressure and short extraction ventilation and dust removal system in the fast-tunneling woking face, the migration and distribution law of the dust in the fast-tunneling woking face was obtained on the basis of the combination of field investigation, field measurement and numerical simulation. According to its law and the existing problems of dust control, the dust removal method of front pressure and rear pumping was innovatively put forward, and the system diagram was designed, which provides a new idea for dust control in fasttunneling woking face. |
