Systems Analysis of an Inherently Explosion-Proof Coal Mining Operation.

摘要

The inherently explosion-proof mine (EPM) concept is based upon the non-flammability of certain combustible-oxidant-inert gas mixtures and the effect of partial pressure of gases on physiological reactions. In a properly controlled underground environment,gas explosions are impossible,men can do work,and relatively high concentrations of methane would be permitted. A systems analysis was performed to examine the physiological,engineering,and economic feasibility of such a concept,and methods and equipment are recommended for maintaining an EPM atmosphere in a bituminous coal mine producing a nominal two million tons of clean coal per year.
