Seismic CDP Profiling in Wells
Authors I. Sanfirov, A. Babkin and T. BaybakovaSummaryWell seismic observations procedure with using CDP acquisition system was proposed. Shot and receiver lines are in different special wells, well sparker is using. Main target in wave field is reflections moving in horizontal direction. It is assumed that these reflections connect with local vertical inhomogeneities. Vertical direction fracture zones are in water protective pillar of potash deposit for example. Results of such kind observations for one of the earth surface fast subsiding area on flooded salt mine territory are presented.

The Test Results of the Seismic Monitoring Systems State of Stability of the Rock Mass in the Process of Construction of Road Tunnels in China
Authors V.B. Pisetski, R. Huang, Y.V. Patrushev, A. E. Zudilin, I.V. Schneider, M.P. Shirobokov and V.Y. BalakinSummaryThe report discusses the results of the test systems seismic monitoring of rock mass in the process of penetration road tunnel in China. Test system MIKON-GEO (LLC Ingorteh, RF), TRT 6000 (Procedia Engineering, USA, China), TST 303 (Amberg Measuring Technique, Switzerland). According to the results made all the systems tests forecasts to detect karst cavities and therefore the water saturation of the array at a distance of 200 m ahead of the tunnel face. After the tests, carried out excavation of the tunnel and made conclusions on the reliability of forecasts, the advantages and disadvantages of test systems and data processing methods.

Concept, System Solutions and the Results of Geotechnical Monitoring and Forecasting of Hazardous Geodynamic Phenomena in the Processes of Underground Mining
Authors V.B. Pisetski, S.V. Kornilkov, A.D. Sashurin, E.S. Lapin, S.E. Lapin and V.Y. BalakinSummaryThe problem of the establishment of effective monitoring systems and forecasting of dangerous dynamic phenomena in the rock mass in the process of underground construction. A promising approach to building security systems of mining is associated with seismic and air and gas resources assessment of the structure and parameters of the stress-strain state of the rock mass.

Highway State Examination Based on Combined Application of Capacitive Coupled Electrical Resistivity Tomography and Ground-Penetrating Radar
Authors D.A. Lalomov and V.V. GlazunovSummaryКомплекс геофизических методов в составе георадиолокации и бесконтактной электротомографии рассмотрен в рамках решения задачи по обследованию автодорог. Выбор данного комплекса обосновывается результатами опытно-методических работ, выполненных на участке новой автодороги с асфальтовым покрытием. Показана эффективность выполнения георадиолокационого зондирования для перехода от временного георадиолокационного разреза к глубинному в условиях отсутствия априорной информации о разрезе. Результаты опытно-методических работ показывают, что комплекс электроразведочных методов, включающий электротомографию и георадиолокацию, помимо информации о строении автодороги, позволяет получать ценную количественную информацию о ее состоянии на основе расчета электрофизических параметров добротности и УЭС.
