摘　　要：通过详细分析当前快掘工作面的防尘现状及长压短抽通风除尘系统应用于快掘工作面存在的问题,在现场调研、现场实测、数值模拟相结合的基础上,得出了快掘工作面粉尘的运移分布规律。根据其规律及当前防尘存在的问题,创新提出了前压后抽除尘方法,并设计了系统图,为快掘工作面粉尘治理提供了新思路。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.
