矿坑煤层自燃机理及防治措施研究

Prevention and management on spontaneous combustion of coal seam in mine

通过对平庄煤业(集团)公司西露天煤矿的地质灾害调查,分析了煤层自燃的化学热力学机理和影响因素。通过对煤中硫的赋存状态及含量、煤岩成分及变质程度、含煤地层构造的发育程度等的分析,阐述了煤层自燃的内部因素;通过对通风、降雨、气温、挖掘等的分析,论述了煤层自燃的外部影响条件。

Writer analyzed systemically the mechanism and the influence factors of the spontaneous combustion in the coal seam by the research in the western open cut coal mine of Pingzhuang Coal Group Company. He explained the interior cauesons of the coal seams spontaneous combustion by analyzing the existent conditions and contents of the sulfur in the coal, the metamorphose grade and components of the coal, the developing grade of the structure of the stratum containing coal and so on.And he also explained the exterior influence factors of the coal seams spontaneous combustion by analyzing the ventilation, the rain fall, the air temperature and the digging.
