Abstract

The invention relates to a blast hole charging auxiliary device. The blast hole charging auxiliary device comprises a vertical pipe and an explosive receiving pipe. The explosive receiving pipe is connected to the side wall of the vertical pipe in an inclined mode, an upper opening of the vertical pipe and an upper opening of the explosive receiving pipe are formed in the same horizontal plane, anopen groove which is parallel to the axis is formed in the side wall of the vertical pipe, and the top of the open groove is a cone which gradually outwards expands from bottom to top. When a blast pipe is charged, the explosive receiving pipe is connected with a charging flexible pipe of an explosive truck; a lower opening of the vertical pipe is put into a blast hole; an explosion initiation bomb is put into the blast hole from the upper opening of the vertical pipe, and a detonating pipe is put into the open groove; the explosive truck beings to charge the blast hole, the charging height of an installed spacer is achieved, and the explosive truck suspends explosive conveying operation; the spacer is put into the blast hole from the upper opening of the vertical pipe (1); and charging operation continues, and the required charging quantity of the blast hole is achieved. By the adoption of the blast hole charging auxiliary device, the spacer and the explosion initiation bomb are rapidly placed, the working efficiency of workers is improved, and the charging time is shortened. The manufacturing cost is low, the blast hole charging auxiliary device is convenient to carry, and the actual engineering problems that the charging process is complex, and time and labor are consumed are solved.

Description

technical field [0001] The invention relates to the field of mining, in particular to an auxiliary device for blasthole charging. Background technique [0002] In open-pit mine blasting, in order to reduce the blasting vibration, interval charging is used. During the charging process of the explosive vehicle, when placing the spacer, the charging tube needs to be lifted to stop charging, resulting in long charging time and complicated operation. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide an auxiliary device for blasthole charging, which can quickly place spacers and detonating bombs, improve the work efficiency of workers, and reduce the charging time. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] An auxiliary device for blasthole charging, comprising a standpipe and a charge pipe, the charge pipe is obliquely connected to the side wall of the...
