降雨量对自燃矸石山爆炸的影响分析

Effect of Rainfall on the Explosion of Coal Gangue Heap

为了分析降雨对煤矸石山爆炸的影响,探讨了煤矸石山与雨水作用的物理爆炸机理.应用热力学原理研究了煤矸石山与雨水作用的化学爆炸机理.分析了不同情形下的爆炸可能性和爆炸类型,并进行爆炸模拟实验来研究雨水对矸石山爆炸的影响.结果表明:下小雨时,矸石山发生的爆炸主要属于化学爆炸;下大雨时,矸石山在温度小于1 200 K下主要是化学爆炸,在温度大于1 200 K下主要属于物理爆炸.降雨量对矸石山的爆炸影响很大,做好降雨季节的矸石山防爆工作是十分必要的.

For analyzing the effect of rainfall on coal gangue heap explosion, the physical explosion mechanism action between coal gangue heap and water was studied. Based on the thermodynamics principle, the chemical explosion mechanism of coal gangue heap was studied. The explosion possibility and types under different conditions were researched, and a simulation explosion experiment was carried out to study the effect of rainfall on coal gangue heap. The results show that it is main chemical explosion when sprinkling. It is main chemical explosion when the temperature is under 1 200 K and main physical explosion when the temperature is over 1 200 K with heavy rain. Rainfall has a great effect on the explosion of coal gangue heap and it is necessary to prevent explosion during rainy season.
