Blasting miss-fire monitoring device and method

Abstract

The invention relates to a blasting miss-fire monitoring device and method. The blasting miss-fire monitoring device comprises monitoring probes and a monitoring host. The monitoring probes transmit monitored blast hole blasting information to the monitoring host. The monitoring probes include pressure sensors, first data collecting cards, MCUs, wireless transmitters, frequency transmitters and first power sources. The pressure sensors transmit detected blasting instant pressure signals to the MCUs through the first data collecting cards. The MCUs treat the received pressure signals and transmit the pressure signals into the monitoring host through the wireless transmitters. Frequency band information is preset in the MCUs, and the frequencies in frequency bands are transmitted to the frequency transmitters through the data collecting cards. The frequency transmitters are used for transmitting the frequencies into the monitoring host. The MCUs are powered through the first power sources. According to the blasting miss-fire monitoring device and method, the technical guarantee is provided for safety of blasting operation personnel, meanwhile, the tunneling speed of a roadway can be increased, blasting scientificity is improved, the safety coefficients of blasting operation are greatly improved, and wide practicability is achieved.

Description

technical field [0001] The invention relates to a blasting rejection monitoring device and monitoring method, in particular to a blasting blasting rejection monitoring device and monitoring method in the field of mine blasting, tunnel blasting, building blasting and other blasting operations. Background technique [0002] In coal mine tunneling, especially in coal mines with relatively small annual output, the degree of mechanization is low and the safety technology is insufficient. Drilling and blasting, as an economical and efficient construction method, has been widely used. However, during the tunneling and blasting of coal mines, due to various reasons, the blasting phenomenon (being commonly called as a squib) occurs continuously during the blasting operation, and sometimes causes injury accidents, which not only affects the blasting effect but also the life safety of the blasting operators. Detonation rejection, that is, the phenomenon that all or part of the detonato...
