| 摘 要： | 内蒙古自治区桌子山煤田赋存着较为稀缺的煤种一焦煤，煤田内存在的火区不仪烧掉了宝贵的焦性煤炭资源，给煤矿生产带来严重的事故隐患，对当地生态环境也造成极大的破坏。经查明区内有26处子火区，分布面积约760万m^2，通过煤田地质特征、煤质特征、地表指示特征、同位素氡气的浓度相对分布特征、物性特征分析了区内煤层发火原因，根据桌子山煤田火区特点，建议采用浅剥、深灌与覆盖相结合的灭火方法，并对火区进行动态监测。

| Abstract: | A rather scarce coal rank-coking coal has hosted in the Zhuozishan coalfield, Inner Mongolia. The burning area has not only burnt away coal resources, but also brought along serious hidden troubles to mine production and huge destruction to local ecological environment. After investigation, there are 26 burning subareas, with total area about 7.6 million m2. Through analyses of burning area geological, coal quality, surface indication, isotope radon concentration and physical characteristics, have worked out causation of coal seam fire ignition in the area. Based on coalfield burning area peculiarity, fire extinguishing method of combined shallow part stripping, deep part grouting and covering has advised, meanwhile, dynamic monitoring on burning area carried out. |
