Abstract
Abstract This invention relates to a land seismic exploration method and apparatus employing a plurality of elongated tubes each having a flexible wall for containing a volume of liquid explosive therein. Each tube is adapted to be detachably connected to either a detonating device for exploding the liquid explosive therein thereby creating a seismic explosion, or to a pressure transducer for monitoring the pressure changes in the liquid explosive caused by the detected seismic pressure waves.

Claim 1
Independent Claim
68 words
A method of land seismic exploration comprising: a. burying at the exploration site at least two hollow members, each being filled with a liquid explosive; b. attaching to one member a pressure transducer; c. attaching to the other member a detonating device; d. igniting the detonating device to detonate said liquid explosive thereby creating a seismic explosion; and e. detecting the reflected seismic signals with the pressure transducer.
Claim 2
Independent Claim
68 words
A method of land seismic exploration comprising: a. burying at the exploration site at least two hollow members, each being filled with a liquid explosive; b. attaching to one member a pressure transducer; c. attaching to the other member a detonating device; d. igniting the detonating device to detonate said liquid explosive thereby creating a seismic explosion; and e. detecting the reflected seismic signals with the pressure transducer.
Claim 3
Independent Claim
86 words
A method of land seismic exploration comprising: a. burying a plurality of elongated tubes, each tube having a flexible wall defining a bore filled with a liquid explosive and having an open end and a closed end; b. plugging the open end of at least one tube with a detonating device; c. plugging the open end of at least another tube with a pressure transducer; d. actuating the detonator; e. detecting seismic signals with said pressure transducer; and f. recording the output of said pressure transducer.
Claim 4
Independent Claim
