高速铁路煤窑采空区综合物探技术探讨

Discussion on Comprehensive Geophysical Exploration Technology in Coal Mined-out Area along High-speed Railway

综合考虑勘探阶段、探测深度和探测精度等因素，探讨了物探方法的选择及其组合，分析了各种方法的特点，归纳了各种方法资料对煤窑采空区所反映的异常特征，并予实例图片说明。目前，通过物探虽可划分煤窑采空区，却存在混判问题，尚应采取其他手段，互为印证。

Considering exploration phases, investigation depth and precision and other factors, this paper discusses the selections and combinations of geophysical exploration methods, analyzes the characteristics of each method and summarizes abnormal characteristics of coal mined-out area reflected by each method together with picture illustration. At present, although geophysical exploration can identify coal mine-out area, it may result in misjudgment, so other measures shall be taken for mutual confirmation.
