Quick charging device and charging method for blasting hole explosion

Abstract

The invention discloses a quick charging device and a charging method for blasting hole explosion. The quick charging device for the blasting hole explosion comprises a semi-round tube (2), the semi-round tube (2) is made of a T-shaped groove hollow semi-round plastic tube, scales (6) are arranged on the outer surface of the T-shaped groove hollow semi-round plastic tube, an oblique tooth (7) is arranged on the bottom of the interior of the T-shaped groove hollow semi-round plastic tube, a fixing plate (3) is fixedly connected to the bottom of a baffle (1), and the fixing plate (3) of the baffle (1) is mounted in the oblique tooth (7). The quick charging device for the blasting hole explosion solves the technical problems that the traditional medicine bundle is bound to a bamboo strip, a stick or other rod-shaped objects to charge in the prior art, so that the charging speed is slow, the ratio error of the blasting hole clogging length and the charging length or the air column length in the blasting hole and the charging length is too large, the effect of blasting stress wave parameters is influenced, and the energy utilization rate of the medicine bundle is reduced.

Description

technical field [0001] The invention belongs to mine and geotechnical engineering blasting technology, in particular to a rapid charging device and a charging method for blasthole blasting. Background technique [0002] The blasthole charge process is not only an important link in mining and rock blasting operations, but also whether the charge is reasonable and accurate has an important impact on the blasting effect. According to theoretical guidance and on-site construction findings, under certain rock and coil conditions, the use of uncoupled charge or spatially spaced charge can increase the proportion of charge used for breaking or throwing rock energy, and improve the effective utilization of charge energy. ; Improve the uniformity of rock crushing, reduce the large block rate, so that the efficiency of rock loading is improved; reduce the consumption of medicine rolls; can effectively protect the new free surface formed during blasting. However, in the traditional on...

Problems solved by technology

[0003] The technical problem to be solved by the present invention is to provide a rapid charging device and charging method for blasthole blasting, so as to solve the problem of using traditional drug rolls bound on bamboo strips, wooden sticks or other rods for charging in the prior art. , not only the charging speed is slow, but also causes the ratio error between the length of the blast hole blockage and the charge length or the air column length in the blast hole and the charge length to be too large, which affects the effect of blasting stress wave parameters and reduces the energy utilization rate of the charge roll, etc. technical problem
