A clearance C is provided between the flexible hose 14 of the high-strength coating portion 11 and the explosive 13 to allow the explosive 13 to move in the axial direction.

The mesh hose 15 of the high-strength coating portion 11 functions as a strength member that can withstand the tensile force generated when the explosion line 10 is set on the minefield in which the mine M is buried. Even if the hose 15 is stretched by the tensile force, as shown in FIG. 2, the tensile force S is not directly applied to the explosive 13 by the clearance C provided between the flexible hose 14 and the explosive 13. Has become.

On the other hand, the flexible hose 14 functions as a protection member for protecting the explosive 13 from disturbance such as friction generated between the explosive cable 10 and the ground when the explosive cable 10 is set on a minefield.

The explosive rope 10 connects a plurality of divided ropes 10A to each other, the high-strength covering portions 11 are connected to each other via a high-strength joint 20, and the explosives 13 are connected to a coupler 30A.
Are connected via

A high-strength joint 20 for connecting the mesh hose 15 together with the flexible hose 14 of the split cord 10A of the explosion cord 10 is fixed with the end of the flexible hose 14 inserted and formed at the end of the mesh hose 15. A socket 22 having a plurality of connection holes 22a into which a plurality of bundle portions 15a are inserted and fixed with an adhesive 21 is provided, and a nut member 23 connecting the sockets 22, 22 attached to the split cable 10A to each other. And opposed sockets 22,
