Abstract: Disclosed herein is a rock blasting method using air bladders embedded in explosives. The rock blasting method includes the step of drilling a plurality of loading holes into a rock to predetermined depths in a predetermined arrangement. Thereafter, the loading holes are loaded with a plurality of initial explosives, a plurality of primers and a plurality of explosives in such a way that one or more air bladders are inserted into each of the loading holes and surrounded by the explosives. Thereafter, the loading holes are stemmed with stemming materials in the portions of the loading holes situated over the explosives. The primers are detonated so that the initial explosives and explosives are blown up. Hence, the loading lengths of the explosives are increased in proportion to the lengths of the air bladders so that a projection area formed on the free face of the rock is increased.

Abstract: A cartridge assembly 10 includes a shell 12 containing a propellant charge 19. At a rear, open end, the shell 12 holds a force amplifying initiating device 20, in turn holding a rim fire primer 22 in operative association with the propellant 19. A firing pin body 40 is movably held within the device 40 to expose a rear of the body 40 to a shock wave to initiate the devise 20. A fore end of the body 40 includes a taper formation 48 having a rounded fore point 50 aligned with an inactive surface of the primer 22 centrally within a firing rim. Inadvertent (mechanical) actuation of the firing pin 40 will fail to cause sufficient and sufficiently fast impingement on the primer to initiate the primer. Only a shock wave can cause initiation. The primer 22 is held in a collar 34 allowing it to flare open upon initiation and holding it within the shell 12 after initiation.

Abstract: A muzzleloading bullet is provided with a pin at its back end for affixing a gas check thereto. Preferably, the pin is generally cylindrical in nature, and has a distal end that is larger compared to its proximal end that is attached to the body of the bullet. The pin therefore “expands” from its proximal to its distal end so that the resilient gas check may snap onto the pin for being secured to the bullet. Also, the expending pin installed in a cylindrical central hole provides a small space or gap between the inner edge/surface of the central hole and the outer surface of the installed pin at one area or all the way around the pin near its proximal end. This gap increases the ease with which exploding gases from behind the gas check in the gun barrel enter the central hole of the gas check and exit between the pin and gas check when the gun is fired, which, in turn, deforms the gas check near the central hole and encourages the separation of the gas check from the bullet.
