PROCESS AND GEAR FOR INSTALLATION OF ELECTRONIC EQUIPMENT UNDER SOFT SURFACE LAYER OF GROUND Russian patent published in 2001 - IPC

Abstract RU 2171480 C2

FIELD: prospecting for fields of mineral resources and supervision of their exploitation. SUBSTANCE: geophone is permanently set in borehole, first series of seismic waves is generated and first series of seismic data is recorded. On passage of sufficiently long time interval during which state of field changes from moment of generation of first series of seismic waves second series of seismic waves is generated and second series of seismic data is recorded. Boreholes are drilled for installation of devices under surface of ground, device is sunk into borehole and is permanently anchored in it. Device for reception of seismic data includes element of geophone operating in X direction, element of geophone operating in Y direction, element of geophone operating in Z direction and case to house these elements which is permanently anchored in borehole. Complex of facilities to collect seismic information incorporates signal source, signal receiver permanently anchored in borehole, control unit which sends and receives information for mentioned above signal source and signal receiver and from them and facilities to transmit data from mentioned control unit and signal receiver and source and back. Complex of facilities for installation of equipment under surface of ground includes drilling equipment, aid to sink device into borehole and aid to anchor device in borehole permanently. EFFECT: increased accuracy and authenticity. 6 cl, 15 dwg
