In the paper / communication, the problem of electrostatic loading of textile fibers in the air pipes is being treated in an innovative way, occasioning explosive hazards. The thematic aspect approached is essentially required in mining security solutions in the underground exploitation of energy coal and coke in the Jiu Valley mines, where methane (CH4) and coal dust are found to form the grizzly atmosphere. It is specified that methane and coal dust in a concentration of 9.8% have the maximum devastating potential of explosion, with all the medical / deadly consequences among people. Observations show that synthetic fibers used in partial air tubes have low electrical conductivity and load significantly, electrostatically. The proposed variant of the authors is to resort to the choice of different textile fibers placed on the stack / range of electrostatic stresses. |
