PROBLEM TO BE SOLVED: To crush rock without generating a large quantity of dust, noise, gas and vibration by arranging a compsn. consisting of aluminum and a metal oxide generating intantaneous reaction energy by the discharge of electric energy between the electrodes of the lower part of the electrode rod to allow the compsn. to discharge. SOLUTION: In rock crushing work, at first, a composition of a mixture consisting of aluminum and a metal oxide is injected in the gap between the electrodes attached to the lower part of an electrode rod 8 at a predetermined rock crushing point and the charging switch of a control panel 7 is turned ON. The voltage converted to high voltage by a high voltage power supply part 3 is applied to a capacitor bank part 1 to charge the capacitor bank part 1 and, after charging is completed, a rock crushing switch is turned ON and a large current is applied to the electrode rod 8 by a switch part 2 to allow the compsn. 12 composed of the mixture of aluminum and the metal oxide between the lower electrodes 11 to discharge to crush rock. The excessive charge left in the capacitor bank part 1 is consumed as heat through a resistor in a first charge damp part 4. |
