摘要
The present invention relates to a blasting method using a liner for detonation and, more specifically, to a blasting method using a liner for detonation, capable of efficiently using energy of detonation reaction by concentrating detonation energy of a booster or a primer to bore and blast a blasting hole on an object to be crushed, such as, a rock and concrete and, also, by amplifying the speed of propagation. The blasting method using the liner for detonation also can improve productivity by improving blasting efficiency in construction such as controlled blasting, air decking, blasting a long hole from blasting a tunnel with a small cross section, blasting a large-scale mine with an opening of 150 mm or greater, and underwater blasting, by improving dead pressing or detonation stop due to a channel effect. Moreover, the blasting method using the liner for detonation can reduce pollution such as vibration and noise. To achieve the purpose of the present invention, the blasting method using the liner for detonation includes: a general charge method of simply arranging and filling an explosive and a detonator in a blasted hole; and methods of forming an empty space between the explosives and between the bored hole and the explosive and filling the explosive therein. The liner (150) is attached to the primer (111) for charge, or the loaded explosives adjacent to the liner are installed at intervals for the charge to improve the effect. Or, the liner is attached to the loaded explosive except for the primer. Or, the loaded explosives adjacent to the liner are installed at the interval (160) for the charge.
