| 摘 要： | 小回线源瞬变电磁法具有受地形、地物影响小及施工效率高的优点,在地形条件复杂地区可以灵活开展探测工作,根据视电阻率拟断面图横向对比并结合已知水文地质资料可以对煤矿采空区富水情况进行定性评价。在内蒙古某矿采空区探测中,采用16匝4m×4m小回线源瞬变电磁法,有效探测深度达到136m,成功圈定该矿积水采空区,为安全生产工作提供了可靠的水文地质资料。

| Abstract: | Small loop TEM has the advantages of not being affected by the terrain and ground features and having high efficiency in engineering construction. Under the complex terrain condition, the exploration work could be flexibly carried out. In this paper, based on the comparison of apparent resistivity sectional transverse and combined with the known hydrogeological data, the water condition in coal goal could be evaluated qualitatively. In the detection of Inner Mongolia ＇s coal goal, the 4m × 4m and 16 turns small loop transient electromagnetic method is adopted to effectively detect 136m in depth, and successfully delineate the water goal, which has provided reliable hydrogeological information for coal mine safety production. |
