What is a Centralised blasting system?
Centralized blasting systems It allows for two-way communication to take place in real time, with an electronic device initiating each blast by means of an electronic starter. The system compromises a blast controller on surface that monitors and reports all data and activities on a real-time system.
What is electronic blasting system?
Digital Blasting Machine is an electronic device used to verify, arm and fire detonators. It is also available with remote control functionality. Wireless Remote Firing Device (WRFD) allows a blaster to control the blasting procedure from a safe distance without the need for a lengthy copper wire link.
What are initiating systems?
An initiation system provides the initial energy required to detonate an explosive used for rock blasting. Initiation systems require: An initial energy source, • A distribution network to deliver the energy to each blasthole, and • An in-hole component to initiate a detonator-sensitive explosive.
What is a detonator in explosive?
blasting cap, also called Detonator, device that initiates the detonation of a charge of a high explosive by subjecting it to percussion by a shock wave.
How do electronic detonators work?
electric detonator – any device containing an initiating or primary explosive that is used for initiating detonation in another explosives material and uses direct electrical energy from the device’s leads (wires, springs, contacts, etc.) to fire an igniter to initiate the device.
What is full form PETN?
PETN, abbreviation of pentaerythritol tetranitrate, a highly explosive organic compound belonging to the same chemical family as nitroglycerin and nitrocellulose.
Who invented RDX?
Georg Friedrich Henning of Germany
RDX was invented by Georg Friedrich Henning of Germany and patented in 1898. But never used until the 2nd World War while most warring powers first adopted this RDX. In the United States, a secret process developed.
Is RDX a primary explosive?
Secondary explosives, like RDX and HMX, do generate massive amounts of gases (e.g., H2, H2O, N2, NO, CO, CO2 et al.)
