摘要
通过系统分析煤矸石堆自燃的主要影响因素,并结合现场调查,揭示出东胜矿区矸石堆自燃的控制因素:水分含量、残煤含量及其氧化性能、碳质沉积岩与外来可燃物,以及矸石堆的堆积方式和堆积的位置。在此基础上,将矸石堆自燃分为高硫助燃、水分催化、残煤氧化和外来可燃物导燃4种类型。这一研究成果,对加深东胜矿区煤矸石堆自燃的研究和治理的认识,甚至对其他煤矿区矸石堆自燃的认识和治理,有一定的参考或借鉴意义。
The paper aims to reveal the control factors of gangue dump spontaneous combustion in Dongsheng mining area through the systematic analysis of gangue dump spontaneous combustion and field investigation. The main control factors are moisture content, residual coal content, its oxidation properties and the mode and place of stack of the coal gangue,carbonaceous sedimentary rock and exotic combustibles. At the base of this, the paper divided the gangue dump spontaneous combustion into four types. There are high-sulfur combustion, moisture catalytic, oxidation of residual coal and exotic combustibles leads to burn. The results of the research have certain reference significance for the research and govern of gangue dump spontaneous combustion in Dongsheng mining area and other place.
