摘要:
Rock dust is applied to a coal mine wall for mine fire suppression in combination with a chemical foam containing a saturated fatty acid, preferably stearic acid, which imparts hydrophobic properties to the rock dust particles, avoiding agglomeration. The rock dust and foam containing a saturated fatty acid are combined by causing the rock dust and foam to flow through separate conduits to a combiner from which the resulting mixture is caused to flow through a nozzle for application to the mine wall.
摘要(中):
结合含有饱和脂肪酸(优选硬脂酸)的化学泡沫,将粉尘施加到矿井壁上以进行矿山灭火,其赋予岩石灰尘颗粒疏水性,避免团聚。 含有饱和脂肪酸的岩屑和泡沫通过使岩石粉尘和泡沫通过分开的管道流到组合器而组合,使得所得混合物从其中流过喷嘴以施加到矿井壁。
