Abstract: | Geophysical techniques are normally employed to explore the subsurface and determine the anomalies but they are always much
larger in dimension. However, a very precise measurement was needed to pin point a misaligned horizontal tunnel made at 47
m depth to intercept an old bore well and rescue a four year child fallen accidently on 9th November at Jagatpura village in Jaipur, India. Due to the greater depth and presence of iron casing, electric power, etc.,
no equipment could work to determine the orientation of the tunnel that has lost its direction. The dimension of the site
and many other constrains didn’t allow conventional geophysical methods to be used. An innovative method was then designed
and successfully applied, which determined 1.92 m deviation of the tunnel end point to the east from the old bore well. The
digging was redirected accordingly and the bore well was intercepted. This paper describes the theoretical background, forward
simulations and the field experiment of the newly designed geophysical method. |
