新疆阜康矿区五宫煤矿含煤地层为八道湾组,可采煤层23层(组),资源储量丰富。该区煤层具有层数多,厚度大,燃点低等特点,在当地炎热干燥的气候条件下极易发生自燃。通过对井田地质勘探资料和煤层煤质资料的分析,了解了自燃对煤层的影响,查清了井田及其附近火烧区的分布,分析了燃烧变质作用带来的煤质指标的变化情况,最终确定井田内煤层自燃的影响范围为35 m。

Badaowan formation is rich of coal resources.It is the coal-bearing strata of WuGong coal mine in FuKang mining area in XinJiang and contains 23 mining coal seams.The coal seams are easy self-ignition under the hot and dry Climate,because coal seams in this area is thick and have low-ignition point.On the basis of geological prospecting data and coal quality material,We determined the location of burning area,recognized the main inlfuence mode to the coal seam,and the change situation of coal quality index inlfuenced by burining medication.At last, the inlfuence scope of the coal spontaneous combustion in this coalifeld is determined as 35 m.
