Due to the common limitations of low water pressure, limited drainage, and small working space on the excavation face, dust prevention is difficult, especially in downhill tunnels. Using water alone as a dust removal medium affects construction.

[0003] However, when using foam dust suppression in existing coal mines, quick-dissolving liquid dust suppressant or foaming agent is often added to the foam generator through a pulse adding device or a venturi tube adding device, and then the foam is covered on the head of the fully mechanized excavation working face through the pipeline to reduce dust drift. Since the addition ratio of quick-dissolving liquid dust suppressant or foaming agent is about 0.5%, the adding device is relatively large in size and heavy in weight.
