Stanovení vlivu příměsi malého množství hořlavého plynu na výbuchové parametry uhelných prachů

Abstract

This thesis focus on the matters of explosion parametres of coal dusts and the effect of addition of combustible gas, methane. At first, the thesis aims to clarify the ways to influence explosion parametres and the issue of hybrid mixtures. In the second part, the thesis presents laboratory tests of influence of addition of various amount of methane to the mixture of coal dust with air and its effect on maximal pressure and maximal rate of pressure rise. In the end, the results are presented and compared to other author’s works.
