Procedure and evidence of seismic research into physical properties of cohesive soils

The article puts forward a procedure to determine structure and physical properties of nearsurface cohesive soil based on seismic surveying. The backbone of the approach is the use of distribution of P- and S-waves obtained from combination of the seismic refraction technique modification and the multichannel surface wave analysis. The recovery of the physical properties uses correlation dependences. The authors give an example of field data processing. The field research covered a section of a motor road where groundwater level is determined and zones subjected to washout and deformation are detected.

Procedure of joint calculation of temperature and ventilation mode in uninterrupted mining in permafrost zone

The authors have developed a procedure for forecasting air flow, air and rock temperatures as well as thawing halo in all roadways of a mine, taking into account stage-wise introduction of new mine workings into the mine ventilation network, or backfilling of the mined-out stopes.     

Low-frequency resonances of seismic luminescence of rocks in a low-energy vibration-seismic field

Results are presented for an investigation of the effect of monochromatic low-frequency vibrations generated by surface sources on the seismic emission of oil-producing strata under in-situ conditions. The resonance nature of seismic luminescence of rocks is detected. The connection of the observed resonance pattern with the block-hierarchical structure of the medium is demonstrated.

Study of the formation and relaxation processes of seismic luminescence for rocks in a low-energy vibration-seismic field

Results are considered for a study under in-situ conditions of the formation and relaxation processes of seismic luminescence of rocks which arises in an oil-producing stratum during its nonlinear interaction with a low-energy vibration-seismic field. The data obtained are of practical importance for optimizing the regime and duration of action on oil deposits. Institute of Mining, Siberian Branch, Russian Academy of Sciences, Novosibirsk.

Influence of the block-hierarchical structure of rocks on the peculiarities of seismic wave propagation

The analysis is performed for the parameters of long pendulum-type waves in a one-dimensional periodic system with an arbitrary hierarchical structure. A case study is carried out into the wave propagation peculiarities in an impact-excited system of equal rigid blocks with parting layers differing in rigidity. The pendulum wave velocity in the automodel block-hierarchical system is determined. __________ Translated from Fiziko-Tekhnicheskie Problemy Razrabotki Poleznykh Iskopaemykh, No. 6, pp. 20–27, November–December, 2007.
