Abstract
A method is discussed for control of anthracite comminution during coal haulage in underground mines. Coal hauled by belt conveyors was sprayed with MFF-M urea formaldehyde resin and oxalic acid used as a hardener. Design of the UAP experimental spraying system successfully tested in some coal mines in the Donbass is shown in a scheme. Effects of anthracite spraying on toxicity of fire gases were analyzed. Gas emission was analyzed at 300 C and at 1000 C. Content of the following compounds in fire gases was determined: hydrocyanic acid, ammonia, nitrogen oxides, formaldehyde, methanol. Evaluations showed that toxicity increase was within the permissible limits with the exception of hydrocyanic acid. In the case of underground fires in areas of haulage lines with resin spraying systems, members of rescue teams should use special equipment protecting the respiratory system from hydrocyanic acid. 2 references.
