摘要
煤矿矸石山喷爆,是煤矿生产中常见的一种灾害。笔者通过灾害个案调查,从通风、降雨、挖掘三个角度探讨了喷爆的形成机制,较为系统地分析了喷爆的影响因素。矸石山中硫化物、油页岩、残存煤等可燃物的成分、含量及聚集状态,矸石的力学性质、破碎程度、堆积形式等是矸石山喷爆的内部原因;通风、降雨、气温、挖掘等燃烧条件的改善,是矸石山喷爆的外部原因。通过本文的分析与研究,旨在加深对矸石山喷爆的认识。为其灾害的预防与治理奠定基础。
Spray explosion of gangue hill is a common calamity in coal mine. This paper studies the forming process and analyses the effect factors about the spray-explosion system atically from ventilation, raining and excavation. The internal reason is composition of combustible substance, accumulation shape and the properities of the gangue. The exterior reason is about the change of the content, ventilation, air temperature and excavation. After the analysis and study , this paper intends to get a deeper understanding of gangue hill抯 explosion. It establishes the foundation for preventing and governing the calamity.
