PURPOSE: A base rock smashing apparatus capable of solving problems such as vibration and scattering pointed out as demerits in using gunpowder process, and a rock blasting apparatus capable of substantially improving construction performance by solving control difficulties in using power impact rock blasting apparatus are provided. CONSTITUTION: The termite rock blasting apparatus(100) comprises cartridge(120); electrolytic material(160) filled in the cartridge; and detonator(140) mounted inside the electrolytic material to operate the electrolytic material, wherein the electrolytic material is a mixture consisting of metallic powder and metal oxides, wherein the detonator is gunpowder, wherein the detonator is operated by electric method or non-electric method, wherein a plurality of the termite rock blasting apparatuses are connected in series or in a row, and wherein the detonator is detonated by trigger unit(300) including external power supply when the termite rock blasting apparatus(100) is covered with vehicle.

PURPOSE: A cut hole-cutting widening typed blasting method for blasting a charge hole is provided to remove blasting vibration generated in blasting a concentrated charge hole and to improve blasting efficiency. CONSTITUTION: A cut hole cutting widening typed blasting method for blasting a charge hole comprises an empty hole(10) penetrated based on a center shaft of a cut unit in a tunnel; a crack inducing hole(20) penetrated with a specific interval; a slanting hole(30) slanted on symmetric shaft; and a vertical hole(40) penetrated to expand the cut unit. A method for blasting a charge hole of cut hole cutting relaxation type comprises a first stage penetrating plural empty holes with a specific interval in a row; a second stage penetrating the crack inducing hole between the empty holes; a third stage penetrating the slating hole corresponding to the empty hole and the crack inducing hole; and a fourth stage penetrating the vertical hole on outside of the slanting hole to expansion of the cut unit. Thereby, the cut hole cutting relaxation typed blasting method removes blasting vibration generated in blasting the charge hole.

PURPOSE: A base rock cutting method and a charge hole arranging structure are provided to reduce over-break, to prevent the relaxation of peripheral base rock by inducing explosive force toward large holes and to reduce the amount of used charge by directing the explosive force. CONSTITUTION: Large holes(11) are drilled in a base rock(1). Many small charge holes(2) are bored between the large holes. Charge is inserted in the small charge holes and exploded. Some charge holes are not contained the charge to direct the explosive force. Trenches are formed around the ground to prevent the transmission of noise and vibration.

PURPOSE: A bench blasting method is provided to perform an ideal blasting by reducing shock due to the blasting and by restraining the breakage of the rocks by increasing the number of free faces by making the explosion energy react to the crushing of rocks much. CONSTITUTION: A bench blasting is completed by forming a downward hole(6) adjacent to blasting holes divided into preliminary crack holes(13) and blasting holes(14) on the upper free face(1) of bench and forming the bottom of the preliminary crack hole on both sides of the bottom of the blasting hole and forming the direction of bottom of the three kinds of holes to be vertical or to be parallel with an inclined free face(2) while having the distance to be in the range of pulverization or crushing. Herein, the preliminary crack holes are broken when stress wave returns at different time of the returning of the stress wave from two free faces. Thereby many cracks are generated around the blasting holes. The continuous blasting of the blasting holes pushes the peripheral rocks. Therefore, four free faces of a castle type are formed around expansion holes(15).
