| 中文摘要: |
| 废弃煤层自燃在我国废弃煤矿中广泛分布,大量数据证明通过单一方法勘查不能准确查明自燃区燃烧状况。在山西宁武煤田废弃矿山治理过程中,为了准确查明自燃区燃烧状况,本次工作综合应用了热红外遥感、高精度磁测、地面活性炭氡气测量和钻探验证的方法,通过对多种物探勘查方法取得的成果进行对比分析,综合确定了火区的边界和层位。经钻孔验证,综合物探解译的边界和深度是可靠的。此次勘查证明,采用热红外遥感、高精度磁测和地面活性炭氡气测量相结合的方法,能够准确的圈定自燃煤层边界和深度,为废弃矿山自燃区的治理提供了科学依据。 |
| 英文摘要: |
| Spontaneous combustion of abandoned coal seam is widely distributed in abandoned coal mines in China. A large number of data prove that the combustion status of spontaneous combustion area cannot be accurately identified by a single method of exploration. In the treatment process of abandoned mine in Ningwu coalfield, the methods of thermal infrared remote sensing, high-precision magnetic survey, surface active carbon radon measurement and drilling verification were applied. Through the comparative analysis of the results obtained by a variety of geophysical exploration methods, the boundary and the depth of the spontaneous combustion area were comprehensively determined. It was verified by drilling that the boundary and the depth integrated geophysical interpretation were reliable. Through this exploration, it was proved that the combination of thermal infrared remote sensing, high-precision magnetic measurement and surface active carbon radon gas measurement could accurately determine the boundary and depth of the spontaneous combustion area, which provided a scientific basis for the treatment of the spontaneous combustion area of abandoned mines. |
