Multiwave Seismic Possibilities and Applications

The indispensable condition of mining safety in the development of water soluble mineral deposits is maintaining waterproofness of the rocks overlying productive deposits. Safety of urban territory above the mines is also urgent. In this article, it is proposed to make use of all seismic information received by three wave types (reflections, refractions and surface waves) and to combine these methods into multi-level complex which can be registered within the scope of single spread. The result of the full-scaled wave field study is plotting aggregate seismological section which takes account of reflection, refraction and surface waves data. This technology makes it possible to solve different types of problems: engineering geological, mining technical, defectoscopic. It is given 3 examples, that shows facilities of proposed method in different mine area: studying shallow layers in salt CDP seismic, interchamber pillar, cunstruction foundation. In CDP method Rayleigh waves are considered as noise, however, they carry useful information concerning near-surface part of the massif. Therefore, they could be used to provide additional data of an object. This can increase the descriptive comprehension of the CDP method.
