Plane wave landscape explosive source

The utility model discloses a plane wave ground explosive seismic focus. On the basis of an original ground directional seismic focus explosive post, a charge structure is improved to increase the exploration discrimination ratio and to enhance explosion energy. According to the principle of explosive plane wave generators, main charge is designed in a round cake-shaped charge structure and is provided with a positioning post, and the main charge and primary explosive use a split combining structure. The number of main charge cakes can be increased or reduced freely according to exploration need. The structure has the characteristics that downward plane waves can be generated, and explosive has high energy using ratio and good excitation effect. The utility model uses an all-plastic casing and can not generate flying sheets. The utility model has safe construction and reliable performance and provides a novel excitation mode for the complex ground exploration.
