Embodiment

[0016] In the open-air deep hole blasting and building demolition blasting project, in the blast hole charging stage, if the top of the blast hole is used to detonate, the power switch of the present invention is turned on, and the present invention is inserted horizontally into the bottom of the charge roll at the bottom of the blast hole; The bottom of the hole is detonated, the power switch of the present invention is turned on, and the present invention is inserted horizontally into the top of the charge roll at the top of the blast hole. After the detonation, the enameled wire melts and connects under the action of the detonation wave, and the radio frequency signal generating module instantly transmits a signal to the computer, which proves that the explosive is completely detonated and no residual explosive remains; Response, remaining drug residue, find out the location of residual drug through the positioning module, and process it.

Abstract

The invention relates to a device for monitoring whether charge in a blast hole is completely detonated or not. The device comprises a power switch, a 6F22 type button cell, a positioning module, a radio frequency signal generation module, a plastic shell, an enameled wire and an enameled wire fixing rod. Wherein the positioning device and the 6F22 type button battery form a closed circuit and are electrified all the time to keep positioning. The enameled wire is connected to the radio frequency signal generation module and merged into a positioning device circuit to form a break-through type circuit, and is instantly connected to excite a signal after being detonated. The power switch is arranged on the top of the plastic shell. According to the device, the functions of accurately judging whether unexploded residual explosive is left in the blast hole or not and positioning the position of the residual explosive in the blast hole can be realized in modern blasting engineering.

Description

Technical field: [0001] The invention relates to the field of engineering blasting, in particular to a device for monitoring whether a charge in a blasthole is completely detonated. Background technique: [0002] In modern blasting engineering, whether it is mine blasting or demolition blasting, perforated charge is the main blasting method. Often, multiple volumes of finished powder rolls may be loaded in one blast hole, and a detonator is used to detonate a single powder roll. To form the detonation of explosives in the borehole. However, in actual construction, the state of the charge roll in the blast hole is unknown, and the gap between the charge rolls and the explosion transmission may be caused by rocks in the blast hole or other factors, resulting in the failure of detonation of part of the charge in the blast hole and the formation of residual explosives. stagnation, seriously endangering the safety of construction workers and the surrounding masses. However, the...
