This machine was made for coal mines since 2005 and optimized according to the customer's needs.
This device has a current output time control module that limits the current output time below 4 milliseconds.
In the blasting devices of coal mines, which are also called anti-grizzo, a control unit for current exit time (anti-grizzo) must be installed, so that the current exit time from the outputs should be less than 4 milliseconds.
Due to the fact that at the moment of explosion, the intermediate gases of the coal layers (methane) are mixed with coal powder, which is called grizo, and in case of the smallest spark, it causes a secondary explosion.
If special detonation devices are not used and depending on the type of device, there may be current inside the detonation circuit for up to 5 seconds, the wires of the circuit connect together and provide the necessary spark for the detonation of the gas, and as a result, it leads to The secondary explosion destroys the tunnel fortifications and the tunnel collapses. So far, thousands of miners have lost their lives in the world using unsafe devices.
