摘要

摘要:
为准确探明新疆哈密某历史小煤窑采空区分布，采用微动和瞬变电磁组合的勘探方法开展采空区探测研究，应用综合物性资料划分地层，利用微动勘探确定采空区位置，瞬变电磁勘探判别采空区赋水性，两种方法相互补充、相互印证，有效减少单一物探方法成果的多解性，为小煤窑采空区探测中物探手段的选取和应用提供参考。

Abstract:
To accurately explore distribution of a historical small coal mine goaf in Hami, Xinjiang, integrated application of microtremor and transient electromagnetic is used for goaf exploration researching. This work use different physical properties data into lithology, use microtremor exploration to determine the goaf position and use transient electromagnetic exploration identify goaf water. Two methods can complement each other, verify each other, and effectively reduce the wrong results of single geophysical method. Which also provides a reference for the selection and application of geophysical exploration means in small mine goaf exploration.
