摘要： PROBLEM TO BE SOLVED: To provide a protection cap with easy attachment to a master die, and to provide a protection cap, a master die with the protection cap, and a loading method of explosives sufficiently suppressing damage to a leg line or a fuse tube of a detonator, even when carrying out mechanical loading.
SOLUTION: The master die 13 with the protection cap is composed by covering the bottomed cylindrical protection cap 15 wherein the inner diameters (d
1 , d
2 ) of openings are the same or larger than the outer diameter (D) of the master die 16, and the outer diameter (d
3 ) is the same or less than a charge hole diameter (t) on the detonator 17 side of the master die 16. The master die 13 with the protection cap is designed to protect the leg line or the fuse tube 18 connected to the detonator 17. On the opening 15c side of the protection cap 15, it is desirable that a guide part such as a slit is provided for guiding the leg line or the fuse tube 18 to the outside of the protection cap 15.

摘要： PROBLEM TO BE SOLVED: To provide a flexible long cable-like explosive, a flexible long cable- like explosive capable of eliminating defect in boosting, a cable-like explosive connecting device for connecting the flexible long cable-like explosives, and one cable-like explosive device prepared by connecting the flexible long cable- like explosives with the cable-like explosive connecting device. SOLUTION: This explosive is constituted of a plastic explosive extrusion- molded into a long rope-like body, a protecting member for covering an outside of the plastic explosive over the whole length, and the connection tool provided at least in one side end part of the plastic explosive. The explosive is constituted of the plastic explosive extrusion-molded into the long rope-like body, the protecting member for covering the outside of the plastic explosive over the whole length, and the connection tool having a liner part arranged with a liner for generating jet and provided at least in the one side end part of the plastic explosive.

摘要： PROBLEM TO BE SOLVED: To prevent a blasting powder from scattering out of a blasting hole by inserting a container made of a gas-permeable film in the blasting hole in a state of covering a charging hose and fixing the charging hose and an opening part of the container to each other and then blowing the blasting powder into the container by pressured air of a charging machine when a water-soluble blasting powder is charged in the blasting hole. SOLUTION: At the time of blasting, a container having an air permeability of 100-10,000 L/m /S is inserted in a blasting hole in a state of covering a charging hole such as fuel explosive loader or the like. Then, if a water-soluble blasting powder (blasting powder) in bulk is charged in a container by pressed air, excessive air is discharged out of the container and the blasting powder remains in the container. The container is brought into close contact with an inner wall of the blasting hole by the charged blasting powder so that the container is interposed between the charged blasting powder and the inner wall of the blasting hole so as to block contact of the blasting powder with water and capacity of the blasting powder is maintained without being deteriorated. Further, if a container having a water-soluble polymer attached to the container in advance is used, water in the blasting hole and the polymer undergo hydration reaction so as to be gelatinized so that penetration of water into the container is highly blocked.
