Zusammenfassung:	PURPOSE:To make it possible to easily carry out crushing pieces of obstructions together with the surrounding earth by drilling vertical explosive charging holes from the ground, and inserting a large number of explosives, detonators and tamping materials into the holes from the ground to ignite to explode. CONSTITUTION:Explosives charging holes 2 are drilled in the centers of underground obstructions in the ground. After that, explosives 3, electric detonators 4 and tamping materials 5 are subsequently charged into the holes 2 from the ground, and after the connection, they are ignited and exploded. According to the constitution, the obstructions are blasted in the ground by only operation from the ground, and crushing pieces can be easily carried out in excavation work to greatly promote execution efficiency.
