The application of shallow seismic exploration technology in the mined-out area investigation under the road
Mined-out area is a major geological risk in the infrastructure construction such as road, railway, dam and so on. We must detect it promptly and carry out comprehensive governance. Because the mined-out areas are quite different from their surrounding rock in material property such as density, velocity, seismic exploration technology for mined areas detection is the important mean of geological disasters survey. From the engineering application, this paper briefly introduces the working principles of seismic exploration techniques, geophysical characteristics of mined areas and the field measurement techniques with some practical examples of mined-out area under road, the corresponding processing and comprehensive analysis are made about the correlative information which is collected by above seismic prospecting measurement, then the development and space distribution of mined-out area are found out, finally it is validated by drilling and scientific warranty could be provided for investigation, design and construction of the section of this road. The result shows that this method has lots of advantages in geological disaster investigation with great detection depth, high resolution and efficiency. It can meet the requirements of high-resolution geological exploration.
