综合物探方法在采空塌陷区地质灾害勘查中的应用

运用工程物探勘查技术，方便、快捷地获得采空塌陷区的空间信息，了解采空塌陷区的范围及地层变形破坏部位，以及采空区地层稳定性及塌陷发展趋势，为后期地质灾害治理工程提供重要基础资料信息。采用综合物探手段能相互印证，相互补充，可明显地提高物探资料的准确度。本文采用高密度电阻率法、浅层地震方法，对凤台县采空塌陷区进行勘查。勘查的实例表明，与传统勘探技术相比，工程物探勘查技术在采空塌陷区地质灾害勘查中具有较高的分辨能力，同时也具有较高的勘探效率和较低的勘探成本。每种方法均能够较好地反映出工作区的实际地质情况，为实际工作的开展提供依据。

The Application of Integrated Geophysical Methods to Investigating Geological Hazards in Mined-out Collapse Areas

It is convenient and fast to obtain space information from goal areas by using en- gineering geophysical technique, get to know the the mined--out collapse areas and the damaged parts of ground deformation, and also the formation stability of goal areas and the tread of the collapse, which provide very important information for the latter geological hazard management project. Based on the integrated geophysical method, the accuracy of collecting geophysical data can be obviously improved. In this paper, the high density resis- tivity method and shallow seismic method are used to investigate Fengtai mined--out col- lapse area. The result shows that compared with the traditional prospecting, the engineer- ing geophysical prospecting techniques provide higher resolution and efficiency and lower cost. So each method can reflect the actual geological conditions , which provides the basis for the actual work.
