【摘要】 分析了内蒙古乌达矿区煤层自然发火的内在原因和外在条件,从内在原因控制角度将乌达矿区8个主要发火煤层划分为高硫助燃型、厚层氧化型和过渡型等3种类型;根据外因条件不同将乌达矿区16个火区划分出大矿采空区起火、小煤窑起火和煤层露头起火3种类型;根据内外因条件不同分别划分的3种类型进行两两组合,将煤层自燃划分出9种成因类型,并将实验区16个火区进行了综合成因分类。更多还原

【Abstract】 The paper analyzes spontaneous combustion internal factors and external conditions. Eight coal seam spontaneous combustion in Wuda coalfield, Inner Mongolia, were divided into 3 types from the viewpoint of internal factor control, viz. high-sulfur combustion-supporting type, thick-layer apt to oxidation type and transition type. According to different external conditions, 16 fire blocks are divided into 3 types: mine vacant space fire, small coal-pit fire and seam outcrop fire. On the based of 3 types from internal reasons and external conditions respectively 9 types of coal seam spontaneous combustion are identified and 16 fire blocks are carried out comprehensive cause classification.更多还原
