Ground receiving system for chamber blasting blind gun detecting

The invention discloses a ground receiving system for chamber blasting blind gun detecting. The ground receiving system comprises a magnetic-field sensor, a data acquiring module, a communication module and a processing and displaying terminal, the magnetic-field sensor detects signals generated by an underground signal generating device buried in the ground and acquires electromagnetic-field characteristics of an explosion area, the electromagnetic-field characteristics are acquired by the data acquiring module, and acquired information is transmitted to the processing and displaying terminal directly or via a communication module. The ground receiving system is used for electromagnetic signal detection of chamber blasting on the ground and judging whether a blind gun in the chamber blasting exists or not, and the ground receiving system has the advantages of high safety and convenience in use, safety of rock excavation is improved, and safety accidents caused by the blind gun can be effectively reduced.
