新疆准南煤田阜康市煤圈沟井田火烧区特征及煤层自燃因素探析

Probe into Fukang City Meiquangou Minefield Burning Area Features and Coal Spontaneous Combustion Factors in Southern Junggar Coalfield,Xinjiang

新疆阜康市煤圈沟井田火烧区点多面广,多沿煤层露头呈带状展布,地貌特征明显。煤层自燃是一个复杂的物理、化学和环境作业过程。通过分析煤层赋存、地质构造、已废小窑和煤质特征,指出煤层自燃是多种内在因素和外在条件综合作用的结果,为煤层自燃发火的预防和综合治理提供一定依据,以便提高煤炭资源的合理开发和利用。

The burning area in the Fukang City Meiquangou minefield,Xinjiang has multiple ignition points in broad area; mostly along coal outcrops and presents zonal distribution with clear topographic features. The coal spontaneous combustion is a complicated physical,chemical and environmental working process. Through coal hosting,geological structure,abandoned small coalmine and coal quality features analyses have pointed out that the coal spontaneous combustion is an integrated result of multiple internal factors and external conditions. The result has provided certain basis for coal spontaneous combustion prevention and comprehensive treatment,so as to improve coal resources reasonable exploitation and utilization.
