Embodiment Construction

[0047] Hereinafter, the technical configuration of the present invention will be described in detail with reference to the accompanying drawings.

[0048] Such as Figure 3 to Figure 4 As shown, the present invention is characterized in that it includes: the steps of drilling holes according to the specified depth and regulation on the rock bed to be intercepted; respectively filling the priming powder 12, the detonator 13 and the explosive into the drilling holes, and at least After one or more filling pipes whose diameter is smaller than that of the drill hole and which have a pipe layer of a specified size inside are inserted into the hole, the outer side of the filling pipe inserted in the hole is wrapped with explosives. In order to ensure that the filling pipe is buried in the The step of loading the filling pipe body and explosives into the charge hole 11 in sequence in the inside of the charge layer 14; the filling step of filling the upper side of the explosive in the...

Abstract

The present invention relates to a rock blasting method using pipes embedded in explosive layers of blast waterhole, namely relates to a method for implementing the rock blasting by which a pipe body does not deform in the water in the ANFO explosive or gel bulk explosive, and by hiding the tubular pipe body recessed in the water in the water in a blasthole, and utilizing the substance in an explosive layer to fill the pipe body. Therefore, the size of the pipe body is increased correspondingly, by prolonging the filling length of the explosive towards an upper free surface, the transmission area of the laccolite at one side of the free surface at blasting is increased, and the total pressure is increased substantially, and accordingly, the whole stone generation amount at the rock blasting is reduced, the explosive use amount also can be reduced, and the damping and sonic boom are reduced.

Description

technical field [0001] The invention relates to a blasting method for a rock disk, in particular to a blasting method for a rock disk by using a filling pipe buried in a charge layer. By burying the filling pipe body with a diameter smaller than that of the borehole in the charge layer, the specific surface area is increased when the rock plate is blasted, so that the explosive force is evenly distributed to the surrounding rock plate in the charge hole, so that not only can Attenuate the blasting vibration and sound amplitude, and extend the filling length of the explosive to the upper side of the blast hole according to the volume of the filling tube buried in the explosive, so as to increase the transmission area of ​​the rock plate on the free side side during the explosion, Or use less explosives. Background technique [0002] According to the prior art, widely used blasting methods for excavating rock plates include: simply dividing explosives and fillers into two par...
