水绿矾对阳泉5矿无烟煤自燃特性的影响

Effects of Water Copperas on Spontaneous Combustion Characteristic of Anthracite from No.5 Coal Mine in Yangquan Mining Area

在讨论水绿矾物理、化学性质的基础上 ,利用差示扫描量热 ( DSC)技术 ,对阳泉 5矿煤样及其所含水绿矾在实验室进行了实验 .结果表明 ,煤中所含的水绿矾暴露于空气中时将会产生大量热量 ,对煤自燃产生促进作用 ,且含量越高 ,影响越大 .

Based on the discussion of the physical and chemical characteristics of water copperas, anthracite and water copperas samples from No.5 Coal Mine in Yang\|quan mining area were tested in laboratory using the technique of differential scanning calorimetry. The results show that water copperas in a coal seam will produce a large amount of heat when it is exposed in air and has a function of speeding anthracite spontaneous combustion, and the effect will increase when the amount of water copperas in a coal seam increases.
