Abstract
An electric power supplying apparatus for a rock explosion cartridge is disclosed. The apparatus includes the following elements. A power source generates an electric energy. A plurality of channels consist of capacitors for storing an electric energy from the power source, explosion cartridges for being exploded by the electric energies of the capacitors, and input switches for switching the capacitors. A controller controls the turning-on/off of the input switches of the plurality of the channels, and the plurality of the channels are connected to the controller in parallel. There are further included the following elements. That is, a charging switch switches a connection between the power source and the capacitor. A discharging resistor is connected to the capacitor in parallel, and a discharging switch switches a connection between the capacitor and the discharging resistor, while the controller controls the turning-on/off of the charging and discharging switches.
