现代勘查技术在蒙东地区煤炭火区中的应用

内蒙古自治区东部五盟市地区即蒙东地区,其褐煤资源丰富,煤炭自燃等级达Ⅰ~Ⅱ级,自燃倾向性为容易自燃—自燃。该地区煤炭资源的燃烧造成严重的人类健康、环境污染和经济损失问题。收集了蒙东地区26处煤(矿)田火区勘查报告、物探总结等资料,结合蒙东地区环境、地质和煤质特点,以现代勘查技术在该区域的实际应用为基础,总结了蒙东地区煤炭火区的遥感影响和地球物理技术特征,综合利用勘探提供的信息圈定火烧区范围、建立燃烧模型,各区均成功地完成了深部钻探验证工作,为灾害区的治理提供了准确的依据。蒙东地区煤炭火区勘查的经验,能够为今后的煤炭火区勘查工作提供指导。

Application of Modern Prospecting Technology in Finding Coalfield Fires in Eastern Inner Mongolia

The eastern Inner Mongolia consists of five cities.The lignite resources are rich in the Eastern.The levels of coal spontaneous combustion reach I-II，belonging to the easy spontaneous combustion or spontaneous combustion.Coalfield fires in this area greatly affect the health of humans and results in the pollution of the environment and economic loss.After collecting the reports of the exploration and the papers of geophysics in the different 26 coal fires in Eastern Inner Mongolia，combining with the environment，geology and coals characteristics in this area，and also based on modern prospecting technology，the characteristics in remote sensing and geophysics in the Eastern are summarized.With the use of the exploration data，the boundary lines of coalfield fires are delineated and the model of coalfield fires is set up.Deep drills in each zone provide an accurate basis for the treatment of disaster zone.The experience of fire prospecting in the Eastern supplies a guide for the exploration of other coalfield fires in future.
