초록

Rock dust is applied to a mine wall for mine fire suppression in combination with a chemical foam, by generating the foam from air and a foamable liquid in a mixing chamber, and delivering the foam through one flexible conduit and a suspension of rock dust in water through another flexible conduit to a combiner, and causing the combined foam, rock dust and water to pass through a flexible hose to a delivery nozzle from which it is applied to a mine wall.

청구항

1. A method of applying rock dust to a mine wall comprising: pumping a mixture of rock dust and water by means of a pump, from said pump through a first conduit, to a combiner;mixing a foamable liquid and air to produce a flowable foam, and delivering the flowable foam through a second conduit to said combiner;combining said mixture of rock dust and water with said flowable foam in said combiner, to produce a mixture of foam, water and rock dust;causing said mixture of foam, water and rock dust to flow from said combiner to a nozzle connected to said com...
