Research On Dust Suppression Of A Copper Mine Underground

With long-term mining and new orebodies proved to be in the deep the dust concentration of each mine underground operation site increased sharply which is a serious threat to safety and health of workers in workspace. In this paper a high pressure spray technology was put forward for dedusting on a mine underground middle crushing station and achieved the desired dedusting effect.

Sources Of Underground Co Crushing And Ambient

Nov 01 2015 The crushing of generated CO is inversely proportional to moisture content in coal. CO production via ambient temperature oxidation is influenced by temperature particle size and ventilation rate etc. Coal with rich aliphatic hydrocarbons and O-containing groups are more susceptible to oxidation at room temperature.
