The Experimental Research on the New Compound Inhibitor for the Coal Heap

Abstract:

In this paper, aimed at the characteristic of the coal heap spontaneous combustion, the coal heap inhibitor component was initially determined through the requirements analysis of the inhibitor’s properties, the orthogonal experiment of film–forming property and heating were conducted, and the experiment of inhibition rate and permeability test about the optimal formula were carried on. The results showed that the inhibition rate of this inhibitor could reach 88%. This showed that a new measure was provided to hold back the coal heap spontaneous combustion, the inhibitor also had a function of restraining coal dust raising as a result of the inhibitor’s film-coverage property.
