摘要
通过对影响近距离煤层自燃因素的分析,应用层次分析法的基本原理建立近距离煤层群联合开采煤自燃的评价层次模型,获得了工作面推进速度是影响该矿煤自燃的首要因素,其次是煤层间距、煤层倾角、层间压差和地质构造等,为矿井主动地选择煤自燃防治措施提供依据。
Through analysis of factors affecting spontaneous combustion in close distance coal seam, the evaluation hierarchy model of coal spontaneous combustion in near distance seams is established by applying the basic principle of analytic hierarchy process (AHP). The speed of working face is the primary factor affecting the coal spontaneous combustion, followed by coal seam spacing,dip angle of coal seam the interlayer pressure difference and geological structure etc, which provides choice for mine coal spontaneous combustion prevention measures.
