煤矸石山自燃机理及灭火技术研究

Spontaneous combustion mechanism of gangue dump and fire extinguishing techniques

日益增加的煤矸石在堆置过程中极易发生自燃,对周围环境和居民造成危害。为了预防和控制煤矸石山的自燃,对煤矸石山的自燃机理、自燃因子进行了分析论述,并对几种常用的灭火技术进行比较,同时对今后预防和控制煤矸石山自燃的研究和应用工作重点提出了见解。认为在今后的工作中,除应继续对煤矸石山的自燃机理和自燃因子展开深入研究外,还应开发在技术、经济、可行性方面更为实用的新技术,尝试通过植被混合种植以改变煤矸石山表面的小气候,防止煤矸石山复燃,进而达到煤矸石山治理的目的。

To prevent and control the spontaneous combustion of gangue dump, analyse its mechanism and spontaneous combustion factors. Compared some fire extinguishing techniques which are frequently used. Through analysis find that, despite the above techniques, some more practical advanced techniques should be investigated from the aspects of economy and feasibility. The climate of gangue dump could improve by mixedly planting vegetation. All there measures serve to prevent spontaneous combustion of gangue dump.
