Programmable Logic Device Used for the Priming of the Blasting Cartridge in Explosive Areas

In this paper we describe a device used in the priming of the electrical blasting cartridge which supplies the whole electrical priming energy. This device offers a much better security compare to the present similar devices because it eliminates the human factor errors. Also this device verifies and monitors the blasting line states and has the ability of blocking the blasting in improper functioning conditions. The system has the possibility of blasting line diagnosis with the state displaying. The device was conceived and tested, and satisfies the expectations in varied working conditions like underground with explosive gases or in quarries
