| 摘 要： | 煤层在燃烧过程中,其围岩受到高温烘烤,致使煤层上、下部围岩裂隙发育,失去了形成层状地震反射的条件,同时在磁性、导电性等方面物理性质也发生显著变化,为地震勘探及磁法勘探的实施提供了理论依据。该文通过实例介绍了利用三维地震勘探和磁法勘探相结合准确圈定各主采煤层火烧区边界的方法及经验。

| Abstract: | During the combustion process of coal strata, under the effect of high temperature, surrounding rocks in the upper and lower part of coal strata developed and lost the conditions for layered seismic reflection. At the same time, there are noticeable changes regarding physical properties, such as magnetism and electric conductivity. It will provide theory basis for seismic surveying and magnetic surveying. In this paper, through practical examples, methods and experiences for precisely delineating boundaries of burning areas in each main coal strata combining seismic surveying and magnetic surveying together have been introduced. |
