GROUND ORIENTING FOCUS BOMB FOR GEOPBYSICAL EXPLORATION

The utility model discloses a ground orienting focus bomb for geophysical exploration. The utility model is a new focus bomb which generates the focus and is suitable to the geological exploration of oilfield, coal, hydrology, etc. The utility model adopts explosion of the cavity effect charge of the bomb and the action principle. When the dynamite explodes, an elastic wave which downward concentrates is generated. The ground orienting focus bomb for geophysical exploration is especially suitable for the areas in where the well construction is extremely difficult, and the ground rocks are continuous and in a large area. The ground orienting focus bomb for geophysical exploration has the advantages of small volume, high power, convenient operation, low cost, high geophysical prospecting quality, etc. Well construction is no need. The ground orienting focus bomb for geophysical exploration has positive meaning to accelerate the speed of geological exploration.
