| 摘 要： | 内蒙古准格尔旗准格尔召镇富含优质煤炭资源，但区内煤层普遍存在自燃现象，致使生态环境明显恶化。以遥感为主要技术手段，结合物探验证、实地调查，查明区内明火点337个，燃烧区面积3．78km^2，潜在危险区达27．38km^2,并对主采煤层露天开采的合理性进行了初步分析，认为3^#煤层适合进行露天开采，既能最大限度开采资源．又能根治煤火；3^#、4^#煤层间距小，大部分4^#煤层可与3^#煤层联合开采。

| Abstract: | There is abundant high quality coal resources around Jungar Ju, Jungar Banner, Inner Mongolia, but because of prevalent spontaneous combustion in the area brings on ecological environment obviously deteriorated. To take remote sensing as main technical means combined with geophysical prospecting validating and field investigation, find out 337 naked fire points, combustion area 3.78km^2 and potential area of danger 27.38km^2. Preliminary analyzed main mineable coal seams surface mining justification, considered that the No.3 coal is appropriate for surface mining, thus can mine coal resource up to the hilt and cure once for spontaneous combustion; and small interval between No.3 coal and No.4 coal, therefore most No.4 coal can be combined mining with No.3 coal. |
