Device for monitoring whether charge in blast hole is completely detonated or not

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...

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 monitoring of residual explosive accumulation is often different from the monitoring of blind artillery. The monitoring of blind artillery is mainly to monitor whether the detonator can successfully detonate the explosive, but the residual explosive that has not been detonated in the blast hole is often not detected.
